Coronary artery disease (CAD) is a pathological process characterized by atherosclerotic plaque accumulation in the epicardial arteries, whether obstructive or non-obstructive. This process can be modified by lifestyle adjustments, pharmacological therapies, and invasive interventions designed to achieve disease stabilization or regression. The disease can have long, stable periods but can also become unstable at any time, typically due to an acute atherothrombotic event caused by plaque rupture or erosion. However, the disease is chronic, most often progressive, and hence serious, even in clinically apparently silent periods. The dynamic nature of the CAD process results in various clinical presentations, which can be conveniently categorized as either acute coronary syndromes (ACS) or chronic coronary syndromes (CCS). The Guidelines presented here refer to the management of patients with CCS. The natural history of CCS is illustrated in Figure 1.

The ESC Guidelines represent the views of the ESC and were produced after careful consideration of the scientific and medical knowledge and the evidence available at the time of their publication.The ESC is not responsible in the event of any contradiction, discrepancy and/or ambiguity between the ESC Guidelines and any other official recommendations or guidelines issued by the relevant public health authorities, in particular in relation to good use of healthcare or therapeutic strategies.Health professionals are encouraged to take the ESC Guidelines fully into account when exercising their clinical judgment, as well as in the determination and the implementation of preventive, diagnostic or therapeutic medical strategies; however, the ESC Guidelines do not override, in any way whatsoever, the individual responsibility of health professionals to make appropriate and accurate decisions in consideration of each patient's health condition and in consultation with that patient and, where appropriate and/or necessary, the patient's caregiver.Nor do the ESC Guidelines exempt health professionals from taking into full and careful consideration the relevant official updated recommendations or guidelines issued by the competent public health authorities, in order to manage each patient's case in light of the scientifically accepted data pursuant to their respective ethical and professional obligations.It is also the health professional's responsibility to verify the applicable rules and regulations relating to drugs and medical devices at the time of prescription.

In patients who have chronic heart failure with reduced left ventricular ejection fraction, severe secondary mitral-valve regurgitation is associated with a poor prognosis. Whether percutaneous mitral-valve repair improves clinical outcomes in this patient population is unknown.We randomly assigned patients who had severe secondary mitral regurgitation (defined as an effective regurgitant orifice area of >20 mm2 or a regurgitant volume of >30 ml per beat), a left ventricular ejection fraction between 15 and 40%, and symptomatic heart failure, in a 1:1 ratio, to undergo percutaneous mitral-valve repair in addition to receiving medical therapy (intervention group; 152 patients) or to receive medical therapy alone (control group; 152 patients). The primary efficacy outcome was a composite of death from any cause or unplanned hospitalization for heart failure at 12 months.At 12 months, the rate of the primary outcome was 54.6% (83 of 152 patients) in the intervention group and 51.3% (78 of 152 patients) in the control group (odds ratio, 1.16; 95% confidence interval [CI], 0.73 to 1.84; P=0.53). The rate of death from any cause was 24.3% (37 of 152 patients) in the intervention group and 22.4% (34 of 152 patients) in the control group (hazard ratio, 1.11; 95% CI, 0.69 to 1.77). The rate of unplanned hospitalization for heart failure was 48.7% (74 of 152 patients) in the intervention group and 47.4% (72 of 152 patients) in the control group (hazard ratio, 1.13; 95% CI, 0.81 to 1.56).Among patients with severe secondary mitral regurgitation, the rate of death or unplanned hospitalization for heart failure at 1 year did not differ significantly between patients who underwent percutaneous mitral-valve repair in addition to receiving medical therapy and those who received medical therapy alone.

Transcatheter aortic-valve implantation (TAVI) is an emerging intervention for the treatment of high-risk patients with severe aortic stenosis and coexisting illnesses. We report the results of a prospective multicenter study of the French national transcatheter aortic-valve implantation registry, FRANCE 2.All TAVIs performed in France, as listed in the FRANCE 2 registry, were prospectively included in the study. The primary end point was death from any cause.A total of 3195 patients were enrolled between January 2010 and October 2011 at 34 centers. The mean (±SD) age was 82.7±7.2 years; 49% of the patients were women. All patients were highly symptomatic and were at high surgical risk for aortic-valve replacement. Edwards SAPIEN and Medtronic CoreValve devices were implanted in 66.9% and 33.1% of patients, respectively. Approaches were either transarterial (transfemoral, 74.6%; subclavian, 5.8%; and other, 1.8%) or transapical (17.8%). The procedural success rate was 96.9%. Rates of death at 30 days and 1 year were 9.7% and 24.0%, respectively. At 1 year, the incidence of stroke was 4.1%, and the incidence of periprosthetic aortic regurgitation was 64.5%. In a multivariate model, a higher logistic risk score on the European System for Cardiac Operative Risk Evaluation (EuroSCORE), New York Heart Association functional class III or IV symptoms, the use of a transapical TAVI approach, and a higher amount of periprosthetic regurgitation were significantly associated with reduced survival.This prospective registry study reflected real-life TAVI experience in high-risk elderly patients with aortic stenosis, in whom TAVI appeared to be a reasonable option.

This trial sought to assess the influence of omeprazole on clopidogrel efficacy. Clopidogrel has proved its benefit in the treatment of atherothrombotic diseases. In a previous observational study, we found clopidogrel activity on platelets, tested by vasodilator-stimulated phosphoprotein (VASP) phosphorylation, to be diminished in patients receiving proton pump inhibitor (PPI) treatment. In this double-blind placebo-controlled trial, all consecutive patients undergoing coronary artery stent implantation received aspirin (75 mg/day) and clopidogrel (loading dose, followed by 75 mg/day) and were randomized to receive either associated omeprazole (20 mg/day) or placebo for 7 days. Clopidogrel effect was tested on days 1 and 7 in both groups by measuring platelet phosphorylated-VASP expressed as a platelet reactivity index (PRI). Our main end point compared PRI value at the 7-day treatment period in the 2 groups. Data for 124 patients were analyzed. On day 1, mean PRI was 83.2% (standard deviation [SD] 5.6) and 83.9% (SD 4.6), respectively, in the placebo and omeprazole groups (p = NS), and on day 7, 39.8% (SD 15.4) and 51.4% (SD 16.4), respectively (p < 0.0001). Omeprazole significantly decreased clopidogrel inhibitory effect on platelet P2Y12 as assessed by VASP phosphorylation test. Aspirin-clopidogrel antiplatelet dual therapy is widely prescribed worldwide, with PPIs frequently associated to prevent gastrointestinal bleeding. The clinical impact of these results remains uncertain but merits further investigation.

Abstract Aims The 2019 report from the European Society of Cardiology (ESC) Atlas provides a contemporary analysis of cardiovascular disease (CVD) statistics across 56 member countries, with particular emphasis on international inequalities in disease burden and healthcare delivery together with estimates of progress towards meeting 2025 World Health Organization (WHO) non-communicable disease targets. Methods and results In this report, contemporary CVD statistics are presented for member countries of the ESC. The statistics are drawn from the ESC Atlas which is a repository of CVD data from a variety of sources including the WHO, the Institute for Health Metrics and Evaluation, and the World Bank. The Atlas also includes novel ESC sponsored data on human and capital infrastructure and cardiovascular healthcare delivery obtained by annual survey of the national societies of ESC member countries. Across ESC member countries, the prevalence of obesity (body mass index ≥30 kg/m2) and diabetes has increased two- to three-fold during the last 30 years making the WHO 2025 target to halt rises in these risk factors unlikely to be achieved. More encouraging have been variable declines in hypertension, smoking, and alcohol consumption but on current trends only the reduction in smoking from 28% to 21% during the last 20 years appears sufficient for the WHO target to be achieved. The median age-standardized prevalence of major risk factors was higher in middle-income compared with high-income ESC member countries for hypertension {23.8% [interquartile range (IQR) 22.5–23.1%] vs. 15.7% (IQR 14.5–21.1%)}, diabetes [7.7% (IQR 7.1–10.1%) vs. 5.6% (IQR 4.8–7.0%)], and among males smoking [43.8% (IQR 37.4–48.0%) vs. 26.0% (IQR 20.9–31.7%)] although among females smoking was less common in middle-income countries [8.7% (IQR 3.0–10.8) vs. 16.7% (IQR 13.9–19.7%)]. There were associated inequalities in disease burden with disability-adjusted life years per 100 000 people due to CVD over three times as high in middle-income [7160 (IQR 5655–8115)] compared with high-income [2235 (IQR 1896–3602)] countries. Cardiovascular disease mortality was also higher in middle-income countries where it accounted for a greater proportion of potential years of life lost compared with high-income countries in both females (43% vs. 28%) and males (39% vs. 28%). Despite the inequalities in disease burden across ESC member countries, survey data from the National Cardiac Societies of the ESC showed that middle-income member countries remain severely under-resourced compared with high-income countries in terms of cardiological person-power and technological infrastructure. Under-resourcing in middle-income countries is associated with a severe procedural deficit compared with high-income countries in terms of coronary intervention, device implantation and cardiac surgical procedures. Conclusion A seemingly inexorable rise in the prevalence of obesity and diabetes currently provides the greatest challenge to achieving further reductions in CVD burden across ESC member countries. Additional challenges are provided by inequalities in disease burden that now require intensification of policy initiatives in order to reduce population risk and prioritize cardiovascular healthcare delivery, particularly in the middle-income countries of the ESC where need is greatest.

Multisite ventricular pacing has recently been proposed as an additional treatment for patients with severe congestive heart failure. To further assess the potential value of this technique, we compared the acute hemodynamic changes associated with pacing the right ventricular apex (RVA) or outflow tract (RVOT) alone, the left ventricle (LV) alone, or biventricular (BIV) pacing of the RVA and LV together.Acute hemodynamic findings were measured in 27 patients with severe heart failure despite optimal therapy and either first-degree AV block and/or an intraventricular conduction defect. In the 23 patients with a high pulmonary capillary wedge pressure (PCWP) (>15 mm Hg), data were collected after transvenous pacing at different ventricular sites in either the VDD mode (AV delay=100 ms) or the VVI mode in patients with atrial fibrillation (n=6). The mean baseline cardiac index was 1.82 L x min(-1) x m(-2). Mean+/-SD baseline systolic blood pressure (SBP) (118.5+/-15.2 mm Hg), PCWP (26.4+/-6.6 mm Hg), and V-wave amplitude (39.1+/-14.6 mm Hg) were similar before and after either RVA or RVOT pacing. In contrast, LV-based pacing (either LV alone or BIV pacing) resulted in higher SBP (P<.03) and lower PCWP (P<.01) and V-wave amplitude (P<.001) than either baseline or RV pacing measurements. With LV pacing alone, SBP, PCWP, and V waves were 126.5+/-15.1, 20.7+/-5.9, and 25.5+/-8.1 mm Hg, respectively. The results with LV pacing alone were similar to those obtained with BIV pacing.In patients with severe congestive heart failure, both LV pacing alone and BIV pacing resulted in a similar and significant acute improvement in SBP, PCWP, and V-wave amplitude compared with baseline measurements and RV pacing alone. These results provide a strong basis for initiating long-term studies examining the chronic effects of LV-based pacing in patients with medically refractory congestive heart failure.

Experimental and clinical evidence suggests that cyclosporine may attenuate reperfusion injury and reduce myocardial infarct size. We aimed to test whether cyclosporine would improve clinical outcomes and prevent adverse left ventricular remodeling.In a multicenter, double-blind, randomized trial, we assigned 970 patients with an acute anterior ST-segment elevation myocardial infarction (STEMI) who were undergoing percutaneous coronary intervention (PCI) within 12 hours after symptom onset and who had complete occlusion of the culprit coronary artery to receive a bolus injection of cyclosporine (administered intravenously at a dose of 2.5 mg per kilogram of body weight) or matching placebo before coronary recanalization. The primary outcome was a composite of death from any cause, worsening of heart failure during the initial hospitalization, rehospitalization for heart failure, or adverse left ventricular remodeling at 1 year. Adverse left ventricular remodeling was defined as an increase of 15% or more in the left ventricular end-diastolic volume.A total of 395 patients in the cyclosporine group and 396 in the placebo group received the assigned study drug and had data that could be evaluated for the primary outcome at 1 year. The rate of the primary outcome was 59.0% in the cyclosporine group and 58.1% in the control group (odds ratio, 1.04; 95% confidence interval [CI], 0.78 to 1.39; P=0.77). Cyclosporine did not reduce the incidence of the separate clinical components of the primary outcome or other events, including recurrent infarction, unstable angina, and stroke. No significant difference in the safety profile was observed between the two treatment groups.In patients with anterior STEMI who had been referred for primary PCI, intravenous cyclosporine did not result in better clinical outcomes than those with placebo and did not prevent adverse left ventricular remodeling at 1 year.

Transcatheter aortic valve implantation is a therapeutic alternative for high-surgical-risk patients with severe symptomatic aortic stenosis. Two models of prosthesis are currently commercialized in France, which can be implanted either via a transarterial or a transapical approach. The aim of the study was to evaluate in a national French registry the early safety and efficacy of transcatheter aortic valve replacement (AVR) using either the Edwards SAPIEN™ or CoreValve™ in high-surgical-risk patients with severe aortic stenosis.The multicentre national registry was conducted in 16 centres between February 2009 and June 2009, under the authority of the French Societies of Cardiology and Thoracic and Cardio-Vascular Surgery. The primary endpoint was mortality at 1 month. Two hundred and forty-four high-surgical-risk patients (logistic EuroSCORE ≥20%, STS ≥10%, or contra-indication to AVR) were enrolled. Mean age was 82 ± 7 years and 43.9% were female. Edwards SAPIEN and CoreValve were implanted in 68 and 32% of patients, respectively. The approaches used were transarterial (transfemoral: 66%; subclavian: 5%) or transapical in 29%. Device success rate was 98.3% and 30-day mortality was 12.7%. Severe complications included stroke (3.6%), tamponade (2%), acute coronary occlusion (1.2%), and vascular complications (7.3%). Pacemaker was required in 11.8%. At 1 month, 88% of patients were in NYHA class II or less.This prospective registry reflects the real-life experience of transcatheter aortic valve implantation in high-risk elderly patients in France. The early results are satisfactory in terms of feasibility, short-term haemodynamic and functional improvement, and safety. Longer term follow-up will be further assessed.

Atrial fibrillation (AF) confers a substantial risk of mortality and morbidity from stroke and thrombo-embolism, and this common cardiac arrhythmia represents a major healthcare burden in Europe.1 Stroke prevention is central to the management of AF patients, with the 2012 focused update of the European Society of Cardiology (ESC) guidelines2 recommending oral anticoagulation (OAC) using well-controlled adjusted dose vitamin K antagonists (VKAs, e.g. warfarin) or non-VKA oral anticoagulants (NOACs, previously referred to as new or novel OACs3) for patients with AF and ≥1 stroke risk factor(s). Also, these guidelines strongly advocate a clinical practice shift so that the initial decision step now is the identification of ‘truly low risk’ patients, essentially those aged <65 years without any stroke risk factor (both male and female), who do not need any antithrombotic therapy.2 The ESC guidelines also recommend the use of the CHA2DS2-VASc score4 for stroke risk assessment, and define ‘low-risk’ patients as those with a CHA2DS2-VASc score = 0 (males) or score = 1 (females). Subsequent to this initial step of identifying the low-risk patients, effective stroke prevention (which is essentially OAC) can then be offered to AF patients with ≥1 stroke risk factor(s), with treatment decisions made in consultation with patients and incorporating their preferences. In everyday clinical practice, over 80% of all patients with AF have an indication for OAC, and vascular disease co-exists in ∼30% of them.5–7 With an estimated prevalence of AF of 1–2% and ∼20% of these requiring percutaneous cardiovascular interventions over time,8 ∼1–2 million AF patients in Europe who are …

In symptomatic patients with suspected coronary artery disease (CAD), computed tomographic angiography (CTA) improves patient selection for invasive coronary angiography (ICA) compared with functional testing. The impact of measuring fractional flow reserve by CTA (FFRCT) is unknown.At 11 sites, 584 patients with new onset chest pain were prospectively assigned to receive either usual testing (n = 287) or CTA/FFR(CT) (n = 297). Test interpretation and care decisions were made by the clinical care team. The primary endpoint was the percentage of those with planned ICA in whom no significant obstructive CAD (no stenosis ≥50% by core laboratory quantitative analysis or invasive FFR < 0.80) was found at ICA within 90 days. Secondary endpoints including death, myocardial infarction, and unplanned revascularization were independently and blindly adjudicated. Subjects averaged 61 ± 11 years of age, 40% were female, and the mean pre-test probability of obstructive CAD was 49 ± 17%. Among those with intended ICA (FFR(CT)-guided = 193; usual care = 187), no obstructive CAD was found at ICA in 24 (12%) in the CTA/FFR(CT) arm and 137 (73%) in the usual care arm (risk difference 61%, 95% confidence interval 53-69, P< 0.0001), with similar mean cumulative radiation exposure (9.9 vs. 9.4 mSv, P = 0.20). Invasive coronary angiography was cancelled in 61% after receiving CTA/FFR(CT) results. Among those with intended non-invasive testing, the rates of finding no obstructive CAD at ICA were 13% (CTA/FFR(CT)) and 6% (usual care; P = 0.95). Clinical event rates within 90 days were low in usual care and CTA/FFR(CT) arms.Computed tomographic angiography/fractional flow reserve by CTA was a feasible and safe alternative to ICA and was associated with a significantly lower rate of invasive angiography showing no obstructive CAD.

The ESC/EACTS Guidelines represent the views of the ESC and the EACTS and were produced after careful consideration of the scientific and medical knowledge and the evidence available at the time of their publication.The ESC and the EACTS are not responsible in the event of any contradiction, discrepancy and/ or ambiguity between the ESC/EACTS Guidelines and any other official recommendations or guidelines issued by the relevant public health authorities, in particular in relation to good use of healthcare or therapeutic strategies.Health professionals are encouraged to take the ESC/EACTS Guidelines fully into account when exercising their clinical judgment, as well as in the determination and the implementation of preventive, diagnostic or therapeutic medical strategies; however, the ESC/ EACTS Guidelines do not override, in any way whatsoever, the individual responsibility of health professionals to make appropriate and accurate decisions in consideration of each patient's health condition and in consultation with that patient and, where appropriate and/or necessary, the patient's caregiver.Nor do the ESC/ EACTS Guidelines exempt health professionals from taking into full and careful consideration the relevant official updated recommendations or guidelines issued by the competent public health authorities, in order to manage each patient's case in light of the scientifically accepted data pursuant to their respective ethical and professional obligations.It is also the health professional's responsibility to verify the applicable rules and regulations relating to drugs and medical devices at the time of prescription.

Whether the direct factor Xa inhibitor rivaroxaban can prevent thromboembolic events after transcatheter aortic-valve replacement (TAVR) is unclear.We randomly assigned 1644 patients without an established indication for oral anticoagulation after successful TAVR to receive rivaroxaban at a dose of 10 mg daily (with aspirin at a dose of 75 to 100 mg daily for the first 3 months) (rivaroxaban group) or aspirin at a dose of 75 to 100 mg daily (with clopidogrel at a dose of 75 mg daily for the first 3 months) (antiplatelet group). The primary efficacy outcome was the composite of death or thromboembolic events. The primary safety outcome was major, disabling, or life-threatening bleeding. The trial was terminated prematurely by the data and safety monitoring board because of safety concerns.After a median of 17 months, death or a first thromboembolic event (intention-to-treat analysis) had occurred in 105 patients in the rivaroxaban group and in 78 patients in the antiplatelet group (incidence rates, 9.8 and 7.2 per 100 person-years, respectively; hazard ratio with rivaroxaban, 1.35; 95% confidence interval [CI], 1.01 to 1.81; P = 0.04). Major, disabling, or life-threatening bleeding (intention-to-treat analysis) had occurred in 46 and 31 patients, respectively (4.3 and 2.8 per 100 person-years; hazard ratio, 1.50; 95% CI, 0.95 to 2.37; P = 0.08). A total of 64 deaths occurred in the rivaroxaban group and 38 in the antiplatelet group (5.8 and 3.4 per 100 person-years, respectively; hazard ratio, 1.69; 95% CI, 1.13 to 2.53).In patients without an established indication for oral anticoagulation after successful TAVR, a treatment strategy including rivaroxaban at a dose of 10 mg daily was associated with a higher risk of death or thromboembolic complications and a higher risk of bleeding than an antiplatelet-based strategy.

Optimal upfront dual antiplatelet therapy (DAPT) duration after complex percutaneous coronary intervention (PCI) with drug-eluting stents (DES) remains unclear. This study investigated the efficacy and safety of long-term (≥12 months) versus short-term (3 or 6 months) DAPT with aspirin and clopidogrel according to PCI complexity. The authors pooled patient-level data from 6 randomized controlled trials investigating DAPT durations after PCI. Complex PCI was defined as having at least 1 of the following features: 3 vessels treated, ≥3 stents implanted, ≥3 lesions treated, bifurcation with 2 stents implanted, total stent length >60 mm, or chronic total occlusion. The primary efficacy endpoint was major adverse cardiac events (MACE), defined as the composite of cardiac death, myocardial infarction, or stent thrombosis. The primary safety endpoint was major bleeding. Intention-to-treat was the primary analytic approach. Of 9,577 patients included in the pooled dataset for whom procedural variables were available, 1,680 (17.5%) underwent complex PCI. Overall, 85% of patients received new-generation DES. At a median follow-up time of 392 days (interquartile range: 366 to 710 days), patients who underwent complex PCI had a higher risk of MACE (adjusted hazard ratio [HR]: 1.98; 95% confidence interval [CI]: 1.50 to 2.60; p < 0.0001). Compared with short-term DAPT, long-term DAPT yielded significant reductions in MACE in the complex PCI group (adjusted HR: 0.56; 95% CI: 0.35 to 0.89) versus the noncomplex PCI group (adjusted HR: 1.01; 95% CI: 0.75 to 1.35; pinteraction = 0.01). The magnitude of the benefit with long-term DAPT was progressively greater per increase in procedural complexity. Long-term DAPT was associated with increased risk for major bleeding, which was similar between groups (pinteraction = 0.96). Results were consistent by per-treatment landmark analysis. Alongside other established clinical risk factors, procedural complexity is an important parameter to take into account in tailoring upfront duration of DAPT.

The currently recommended duration of dual antiplatelet therapy (DAPT) in drug-eluting stent (DES) recipients is 12 months to reduce the risk of late stent thrombosis, particularly in those with acute coronary syndrome (ACS). This study hypothesized that antiplatelet treatment with DAPT for 6 months may be noninferior to 24-month DAPT in aspirin-sensitive patients. A multicenter, randomized study assigned patients undergoing implantation of everolimus-eluting stents with confirmed nonresistance to aspirin to receive 6- or 24-month DAPT. The primary endpoint was a composite of death, myocardial infarction, urgent target vessel revascularization, stroke, and major bleeding at 12 months post-stenting. A total of 2,031 patients were enrolled in 70 European and Middle Eastern centers. The trial was prematurely terminated due to recruitment problems, leaving 941 patients randomized to 24-month DAPT and 953 to 6-month DAPT. The 2 treatment groups had similar baseline and procedural characteristics. There was no significant difference in the primary endpoint (24-month: 1.5% vs. 6-month: 1.6%; p = 0.85). Noninferiority was demonstrated for 6- versus 24-month DAPT, with an absolute risk difference of 0.11% (95% confidence interval: −1.04% to 1.26%; p for noninferiority = 0.0002). There were no significant differences in stent thrombosis or bleeding complications. In the 792 (44%) high-risk patients with ACS, primary and secondary endpoints did not significantly differ (hazard ratio: 1.7 [95% confidence interval: 0.519 to 6.057; p = 0.361]). Rates of bleeding and thrombotic events were not significantly different according to 6- versus 24-month DAPT after PCI with new-generation DES in good aspirin responders.

Coronary computed tomographic angiography (CTA) plus estimation of fractional flow reserve using CTA (FFRCT) safely and effectively guides initial care over 90 days in patients with stable chest pain. Longer-term outcomes are unknown.The study sought to determine the 1-year clinical, economic, and quality-of-life (QOL) outcomes of using FFRCT instead of usual care.Consecutive patients with stable, new onset chest pain were managed by either usual testing (n = 287) or CTA (n = 297) with selective FFRCT (submitted in 201, analyzed in 177); 581 of 584 (99.5%) completed 1-year follow-up. Endpoints were adjudicated major adverse cardiac events (MACE) (death, myocardial infarction, unplanned revascularization), total medical costs, and QOL.Patients averaged 61 years of age with a mean 49% pre-test probability of coronary artery disease. At 1 year, MACE events were infrequent, with 2 in each arm of the planned invasive group and 1 in the planned noninvasive cohort (usual care strategy). In the planned invasive stratum, mean costs were 33% lower with CTA and selective FFRCT ($8,127 vs. $12,145 usual care; p < 0.0001); in the planned noninvasive stratum, mean costs did not differ when using an FFRCT cost weight of zero ($3,049 FFRCT vs. $2,579; p = 0.82), but were higher when using an FFRCT cost weight equal to CTA. QOL scores improved overall at 1 year (p < 0.001), with similar improvements in both groups, apart from the 5-item EuroQOL scale scores in the noninvasive stratum (mean change of 0.12 for FFRCT vs. 0.07 for usual care; p = 0.02).In patients with stable chest pain and planned invasive coronary angiography, care guided by CTA and selective FFRCT was associated with equivalent clinical outcomes and QOL, and lower costs, compared with usual care over 1-year follow-up.

Transcatheter aortic valve replacement (TAVR) is standard therapy for patients with severe aortic stenosis who are at high surgical risk. However, national data regarding procedural characteristics and clinical outcomes over time are limited.The aim of this study was to assess nationwide performance trends and clinical outcomes of TAVR during a 6-year period.TAVRs performed in 48 centers across France between January 2013 and December 2015 were prospectively included in the FRANCE TAVI (French Transcatheter Aortic Valve Implantation) registry. Findings were further compared with those reported from the FRANCE 2 (French Aortic National CoreValve and Edwards 2) registry, which captured all TAVRs performed from January 2010 to January 2012 across 34 centers.A total of 12,804 patients from FRANCE TAVI and 4,165 patients from FRANCE 2 were included in this analysis. The median age of patients was 84.6 years, and 49.7% were men. FRANCE TAVI participants were older but at lower surgical risk (median logistic European System for Cardiac Operative Risk Evaluation [EuroSCORE]: 15.0% vs. 18.4%; p < 0.001). More than 80% of patients in FRANCE TAVI underwent transfemoral TAVR. Transesophageal echocardiography guidance decreased from 60.7% to 32.3% of cases, whereas more recent procedures were increasingly performed in hybrid operating rooms (15.8% vs. 35.7%). Rates of Valve Academic Research Consortium-defined device success increased from 95.3% in FRANCE 2 to 96.8% in FRANCE TAVI (p < 0.001). In-hospital and 30-day mortality rates were 4.4% and 5.4%, respectively, in FRANCE TAVI compared with 8.2% and 10.1%, respectively, in FRANCE 2 (p < 0.001 for both). Stroke and potentially life-threatening complications, such as annulus rupture or aortic dissection, remained stable over time, whereas rates of cardiac tamponade and pacemaker implantation significantly increased.The FRANCE TAVI registry provided reassuring data regarding trends in TAVR performance in an all-comers population on a national scale. Nonetheless, given that TAVR indications are likely to expand to patients at lower surgical risk, concerns remain regarding potentially life-threatening complications and pacemaker implantation.

Primary percutaneous coronary intervention (PPCI) is the preferred reperfusion therapy in ST-elevation myocardial infarction (STEMI). We conducted this study to evaluate the contemporary status on the use and type of reperfusion therapy in patients admitted with STEMI in the European Society of Cardiology (ESC) member countries. A cross-sectional descriptive study based on aggregated country-level data on the use of reperfusion therapy in patients admitted with STEMI during 2010 or 2011. Thirty-seven ESC countries were able to provide data from existing national or regional registries. In countries where no such registries exist, data were based on best expert estimates. Data were collected on the use of STEMI reperfusion treatment and mortality, the numbers of cardiologists, and the availability of PPCI facilities in each country. Our survey provides a brief data summary of the degree of variation in reperfusion therapy across Europe. The number of PPCI procedures varied between countries, ranging from 23 to 884 per million inhabitants. Primary percutaneous coronary intervention and thrombolysis were the dominant reperfusion strategy in 33 and 4 countries, respectively. The mean population served by a single PPCI centre with a 24-h service 7 days a week ranged from 31 300 inhabitants per centre to 6 533 000 inhabitants per centre. Twenty-seven of the total 37 countries participated in a former survey from 2007, and major increases in PPCI utilization were observed in 13 of these countries. Large variations in reperfusion treatment are still present across Europe. Countries in Eastern and Southern Europe reported that a substantial number of STEMI patients are not receiving any reperfusion therapy. Implementation of the best reperfusion therapy as recommended in the guidelines should be encouraged.

AimsTo evaluate the safety, efficacy, and performance of the TriGuard™ HDH Embolic Deflection Device (TriGuard) compared with no cerebral protection in patients undergoing transcatheter aortic valve implantation (TAVI).

Background— Significant postprocedural aortic regurgitation (AR) is observed in 10% to 20% of cases after transcatheter aortic valve replacement (TAVR). The prognostic value and the predictors of such a complication in balloon-expandable (BE) and self-expandable (SE) TAVR remain unclear. Methods and Results— TAVR was performed in 3195 consecutive patients at 34 hospitals. Postprocedural transthoracic echocardiography was performed in 2769 (92%) patients of the eligible population, and these patients constituted the study group. Median follow-up was 306 days (Q1–Q3=178–490). BE and SE devices were implanted in 67.6% (n=1872) and 32.4% (n=897). Delivery was femoral (75.3%) or nonfemoral (24.7%). A postprocedural AR≥grade 2 was observed in 15.8% and was more frequent in SE (21.5%) than in BE-TAVR (13.0%, P =0.0001). Extensive multivariable analysis confirmed that the use of a SE device was one of the most powerful independent predictors of postprocedural AR≥grade 2. For BE-TAVR, 8 independent predictors of postprocedural AR≥grade 2 were identified including femoral delivery ( P =0.04), larger aortic annulus ( P =0.0004), and smaller prosthesis diameter ( P =0.0001). For SE-TAVR, 2 independent predictors were identified including femoral delivery( P =0.0001). Aortic annulus and prosthesis diameter were not predictors of postprocedural AR for SE-TAVR. A postprocedural AR≥grade 2, but not a postprocedural AR=grade 1, was a strong independent predictor of 1-year mortality for BE (hazard ratio=2.50; P =0.0001) and SE-TAVR (hazard ratio=2.11; P =0.0001). Although postprocedural AR≥grade 2 was well tolerated in patients with AR≥grade 2 at baseline (1-year mortality=7%), it was associated with a very high mortality in other subgroups: renal failure (43%), AR&lt;grade 2 at baseline (31%), low transaortic gradient (35%), or nonfemoral delivery (45%). Conclusions— Postprocedural AR≥grade 2 was observed in 15.8% of successful TAVR and was the strongest independent predictor of 1-year mortality. The use of the SE device was a powerful independent predictor of postprocedural AR≥grade 2.

Decision making for intervention in symptomatic aortic stenosis should balance the risks of surgery and of transcatheter aortic valve implantation (TAVI). We identified the factors associated with early mortality after TAVI and aimed to develop and validate a simple risk score.A population of 3833 consecutive patients was randomly split into two cohorts comprising 2552 and 1281 patients, used respectively to develop and validate a scoring system predicting 30-day or in-hospital mortality.TAVI was performed using the Edwards Sapien prosthesis in 2551 (66.8%) patients and the Medtronic Corevalve in 1270 (33.2%). Approach was transfemoral in 2801 (73.4%) patients, transapical in 678 (17.8%), subclavian in 219 (5.7%) and other in 117 (3.1%). Early mortality was 10.0% (382 patients). A multivariate logistic model identified the following predictive factors of early mortality: age ≥90 years, body mass index <30 Kg/m(2), New York Heart Association class IV, pulmonary hypertension, critical haemodynamic state, ≥2 pulmonary oedemas during the last year, respiratory insufficiency, dialysis and transapical or other (transaortic and transcarotid) approaches. A 21-point predictive score was derived. C-index was 0.67 for the score in the development cohort and 0.59 in the validation cohort. There was a good concordance between predicted and observed 30-day mortality rates in the development and validation cohorts.Early mortality after TAVI is mainly related to age, the severity of symptoms, comorbidities and transapical approach. A simple score can be used to predict early mortality after TAVI. The moderate discrimination is however a limitation for the accurate identification of high-risk patients.

There has been conflicting clinical evidence as to the influence of female sex on outcomes after transcatheter aortic valve replacement. The aim of this study was to evaluate the impact of sex on early and late mortality and safety end points after transcatheter aortic valve replacement using a collaborative meta-analysis of patient-level data. From the MEDLINE, Embase, and the Cochrane Library databases, data were obtained from 5 studies, and a database containing individual patient-level time-to-event data was generated from the registry of each selected study. The primary outcome of interest was all-cause mortality. The safety end point was the combined 30-day safety end points of major vascular complications, bleeding events, and stroke, as defined by the Valve Academic Research Consortium when available. Five studies and their ongoing registry data, comprising 11,310 patients, were included. Women constituted 48.6% of the cohort and had fewer comorbidities than men. Women had a higher rate of major vascular complications (6.3% vs. 3.4%; p < 0.001), major bleeding events (10.5% vs. 8.5%; p = 0.003), and stroke (4.4% vs. 3.6%; p = 0.029) but a lower rate of significant aortic incompetence (grade ≥2; 19.4% vs. 24.5%; p < 0.001). There were no differences in procedural and 30-day mortality between women and men (2.6 % vs. 2.2% [p = 0.24] and 6.5% vs. 6.5% [p = 0.93], respectively), but female sex was independently associated with improved survival at median follow-up of 387 days (interquartile range: 192 to 730 days) from the index procedure (adjusted hazard ratio: 0.79; 95% confidence interval: 0.73 to 0.86; p = 0.001). Although women experience more bleeding events, as well as vascular and stroke complications, female sex is an independent predictor of late survival after transcatheter aortic valve replacement. This should be taken into account during patient selection for this procedure.

Fractional flow reserve estimated using computed tomography (FFRCT) might improve evaluation of patients with chest pain.The authors sought to determine the effect on cost and quality of life (QOL) of using FFRCT instead of usual care to evaluate stable patients with symptoms suspicious for coronary disease.Symptomatic patients without known coronary disease were enrolled into 2 strata based on whether invasive or noninvasive diagnostic testing was planned. In each stratum, consecutive observational cohorts were evaluated with either usual care or FFRCT. The number of diagnostic tests, invasive procedures, hospitalizations, and medications during 90-day follow-up were multiplied by U.S. cost weights and summed to derive total medical costs. Changes in QOL from baseline to 90 days were assessed using the Seattle Angina Questionnaire, the EuroQOL, and a visual analog scale.In the 584 patients, 74% had atypical angina, and the pre-test probability of coronary disease was 49%. In the planned invasive stratum, mean costs were 32% lower among the FFRCT patients than among the usual care patients ($7,343 vs. $10,734 p < 0.0001). In the noninvasive stratum, mean costs were not significantly different between the FFRCT patients and the usual care patients ($2,679 vs. $2,137; p = 0.26). In a sensitivity analysis, when the cost weight of FFRCT was set to 7 times that of computed tomography angiography, the FFRCT group still had lower costs than the usual care group in the invasive testing stratum ($8,619 vs. $ 10,734; p < 0.0001), whereas in the noninvasive testing stratum, when the cost weight of FFRCT was set to one-half that of computed tomography angiography, the FFRCT group had higher costs than the usual care group ($2,766 vs. $2,137; p = 0.02). Each QOL score improved in the overall study population (p < 0.0001). In the noninvasive stratum, QOL scores improved more in FFRCT patients than in usual care patients: Seattle Angina Questionnaire 19.5 versus 11.4, p = 0.003; EuroQOL 0.08 versus 0.03, p = 0.002; and visual analog scale 4.1 versus 2.3, p = 0.82. In the invasive cohort, the improvements in QOL were similar in the FFRCT and usual care patients.An evaluation strategy based on FFRCT was associated with less resource use and lower costs within 90 days than evaluation with invasive coronary angiography. Evaluation with FFRCT was associated with greater improvement in quality of life than evaluation with usual noninvasive testing.

Abstract Aims The MITRA‐FR trial showed that among symptomatic patients with severe secondary mitral regurgitation, percutaneous repair did not reduce the risk of death or hospitalization for heart failure at 12 months compared with guideline‐directed medical treatment alone. We report the 24‐month outcome from this trial. Methods and results At 37 centres, we randomly assigned 304 symptomatic heart failure patients with severe secondary mitral regurgitation (effective regurgitant orifice area &gt;20 mm 2 or regurgitant volume &gt;30 mL), and left ventricular ejection fraction between 15% and 40% to undergo percutaneous valve repair plus medical treatment (intervention group, n = 152) or medical treatment alone (control group, n = 152). The primary efficacy outcome was the composite of all‐cause death and unplanned hospitalization for heart failure at 12 months. At 24 months, all‐cause death and unplanned hospitalization for heart failure occurred in 63.8% of patients (97/152) in the intervention group and 67.1% (102/152) in the control group [hazard ratio (HR) 1.01, 95% confidence interval (CI) 0.77–1.34]. All‐cause mortality occurred in 34.9% of patients (53/152) in the intervention group and 34.2% (52/152) in the control group (HR 1.02, 95% CI 0.70–1.50). Unplanned hospitalization for heart failure occurred in 55.9% of patients (85/152) in the intervention group and 61.8% (94/152) in the control group (HR 0.97, 95% CI 0.72–1.30). Conclusions In patients with severe secondary mitral regurgitation, percutaneous repair added to medical treatment did not significantly reduce the risk of death or hospitalization for heart failure at 2 years compared with medical treatment alone.

Spontaneous coronary artery dissection (SCAD) is an increasingly recognized cause of acute coronary syndromes (ACS) afflicting predominantly younger to middle-aged women. Observational studies have reported a high prevalence of extracoronary vascular anomalies, especially fibromuscular dysplasia (FMD) and a low prevalence of coincidental cases of atherosclerosis. PHACTR1/EDN1 is a genetic risk locus for several vascular diseases, including FMD and coronary artery disease, with the putative causal noncoding variant at the rs9349379 locus acting as a potential enhancer for the endothelin-1 (EDN1) gene.This study sought to test the association between the rs9349379 genotype and SCAD.Results from case control studies from France, United Kingdom, United States, and Australia were analyzed to test the association with SCAD risk, including age at first event, pregnancy-associated SCAD (P-SCAD), and recurrent SCAD.The previously reported risk allele for FMD (rs9349379-A) was associated with a higher risk of SCAD in all studies. In a meta-analysis of 1,055 SCAD patients and 7,190 controls, the odds ratio (OR) was 1.67 (95% confidence interval [CI]: 1.50 to 1.86) per copy of rs9349379-A. In a subset of 491 SCAD patients, the OR estimate was found to be higher for the association with SCAD in patients without FMD (OR: 1.89; 95% CI: 1.53 to 2.33) than in SCAD cases with FMD (OR: 1.60; 95% CI: 1.28 to 1.99). There was no effect of genotype on age at first event, P-SCAD, or recurrence.The first genetic risk factor for SCAD was identified in the largest study conducted to date for this condition. This genetic link may contribute to the clinical overlap between SCAD and FMD.

Few data exist on patients with low-flow, low-gradient aortic stenosis (LFLG-AS) undergoing transcatheter aortic valve replacement (TAVR). Also, very scarce data exist on the usefulness of dobutamine stress echocardiography (DSE) before TAVR in these patients.The authors sought to evaluate clinical outcomes and changes in left ventricular ejection fraction (LVEF) following TAVR in patients with classical LFLG-AS.This multicenter registry included 287 patients with LFLG-AS undergoing TAVR. DSE was performed before TAVR in 234 patients and the presence of contractile reserve was defined as an increase of ≥20% in stroke volume. Transthoracic echocardiography was repeated at hospital discharge and at 1-year follow-up. Clinical follow-up was obtained at 1 and 12 months, and yearly thereafter.The median Society of Thoracic Surgeons score of the study population was 7.7% (interquartile range 5.3% to 12.0%), and the mean LVEF and transvalvular gradient were 30.1 ± 9.7% and 25.4 ± 6.6 mm Hg, respectively. The presence of contractile reserve was observed in 45% of patients at DSE. Mortality rates were 3.8%, 20.1%, and 32.3% at 30 days, 1 year, and 2 years, respectively. On multivariable analysis, chronic obstructive pulmonary disease (p = 0.022) and lower hemoglobin values (p < 0.001) were associated with all-cause mortality. Lower hemoglobin values (p = 0.004) and moderate-to-severe aortic regurgitation post-TAVR (p = 0.018) were predictors of the composite of mortality and rehospitalization due to heart failure. LVEF increased by 8.3% (95% confidence interval: 6% to 11%) at 1-year follow-up, and the lack of prior coronary artery bypass graft (p = 0.004), a lower LVEF at baseline (p < 0.001), and a lower stroke volume index at baseline (p = 0.019) were associated with greater increase in LVEF. The absence of contractile reserve at baseline DSE was not associated with any negative effect on clinical outcomes or LVEF changes at follow-up.TAVR was associated with good periprocedural outcomes in patients with LFLG-AS. However, approximately one-third of LFLG-AS TAVR recipients died at 2-year follow-up, with pulmonary disease, anemia, and residual paravalvular leaks associated with poorer outcomes. LVEF improved following TAVR, but DSE failed to predict clinical outcomes or LVEF changes over time.

A passage under the title "Indications for intervention" should read, "women with low BSA, TGFBR2 mutation, and severe extra-aortic features", instead of "women with low BSA, patients with a TGFBR2 mutation, or patients with severe extra-aortic features that appear to be at particularly high risk".Note 'e' from the legend for the table titled Recommendations on indications for surgery in (A) severe aortic regurgitation and (B) aortic root or tubular ascending aortic aneurysm (irrespective of the severity of aortic regurgitation) should read, "A lower threshold of 40 mm may be considered in women with low BSA" instead of "A lower threshold of 40 mm may be considered in women with low BSA, in patients with a TGFBR2 mutation or in patients with severe extra-aortic features".

Background: No randomized study powered to compare balloon expandable (BE) with self expanding (SE) transcatheter heart valves (THVs) on individual end points after transcatheter aortic valve replacement has been conducted to date. Methods: From January 2013 to December 2015, the FRANCE-TAVI nationwide registry (Registry of Aortic Valve Bioprostheses Established by Catheter) included 12 141 patients undergoing BE-THV (Edwards, n=8038) or SE-THV (Medtronic, n=4103) for treatment of native aortic stenosis. Long term mortality status was available in all patients (median 20 months; interquartile range, 14 to 30). Patients treated with BE-THV (n=3910) were successfully matched 1:1 with 3910 patients treated with SE-THV by using propensity score (25 clinical, anatomical, and procedural variables) and by date of the procedure (within 3 months). The first coprimary outcome was ≥ moderate occurrence of paravalvular regurgitation or in-hospital mortality, or both. The second coprimary outcome was 2-year all-cause mortality. Results: In propensity–matched analyses, the incidence of the first coprimary outcome was higher with SE-THV (19.8%) compared with BE-THV (11.9%; relative risk, 1.68 [95% CI, 1.46–1.91]; P &lt;0.0001). Each component of the outcome was also higher in patients receiving SE-THV: ≥ moderate paravalvular regurgitation (15.5% versus 8.3%; relative risk, 1.90 [95% CI, 1.63–2.22]; P &lt;0.0001) and in hospital mortality (5.6% versus 4.2%; relative risk, 1.34 [95% CI, 1.07–1.66]; P =0.01). During follow up, all cause mortality occurred in 899 patients treated with SE-THV (2-year mortality, 29.8%) and in 801 patients treated with BE-THV (2-year mortality, 26.6%; hazard ratio, 1.17 [95% CI, 1.06–1.29]; P =0.003). Similar results were found using inverse probability of treatment weighting using propensity score analysis. Conclusion: The present study suggests that use of SE-THV was associated with a higher risk of paravalvular regurgitation and higher in-hospital and 2-year mortality compared with use of BE-THV. These data strongly support the need for a randomized trial sufficiently powered to compare the latest generation of SE-THV and BE-THV. Clinical Trial Registration: https://www.clinicaltrials.gov .

The coronavirus disease 2019 (COVID-19) pandemic poses an unprecedented challenge to healthcare worldwide. The infection can be life threatening and require intensive care treatment. The transmission of the disease poses a risk to both patients and healthcare workers. The number of patients requiring hospital admission and intensive care may overwhelm health systems and negatively affect standard care for patients presenting with conditions needing emergency interventions. This position statements aims to assist cardiologists in the invasive management of acute coronary syndrome (ACS) patients in the context of the COVID-19 pandemic. To that end, we assembled a panel of interventional cardiologists and acute cardiac care specialists appointed by the European Association of Percutaneous Cardiovascular Interventions (EAPCI) and from the Acute Cardiovascular Care Association (ACVC) and included the experience from the first and worst affected areas in Europe. Modified diagnostic and treatment algorithms are proposed to adapt evidence-based protocols for this unprecedented challenge. Various clinical scenarios, as well as management algorithms for patients with a diagnosed or suspected COVID-19 infection, presenting with ST- and non-ST-segment elevation ACS are described. In addition, we address the need for re-organization of ACS networks, with redistribution of hub and spoke hospitals, as well as for in-hospital reorganization of emergency rooms and cardiac units, with examples coming from multiple European countries. Furthermore, we provide a guidance to reorganization of catheterization laboratories and, importantly, measures for protection of healthcare providers involved with invasive procedures.

Abstract Transcatheter aortic valve implantation (TAVI) is effective in older patients with symptomatic severe aortic stenosis, while the indication has recently broadened to younger patients at lower risk. Although thromboembolic and bleeding complications after TAVI have decreased over time, such adverse events are still common. The recommendations of the latest 2017 ESC/EACTS Guidelines for the management of valvular heart disease on antithrombotic therapy in patients undergoing TAVI are mostly based on expert opinion. Based on recent studies and randomized controlled trials, this viewpoint document provides updated therapeutic insights in antithrombotic treatment during and after TAVI.

The respective roles of oral anticoagulation or antiplatelet therapy following transcatheter aortic valve implantation (TAVI) remain debated. ATLANTIS is an international, randomized, open-label, superiority trial comparing apixaban to the standard of care.After successful TAVI, 1500 patients were randomized (1:1) to receive apixaban 5 mg (2.5 mg if impaired renal function or concomitant antiplatelet therapy) (n = 749) twice daily, or standard of care (n = 751). Randomization was stratified by the need for chronic anticoagulation therapy. Standard-of-care patients received a vitamin K antagonist (VKA) (Stratum 1) or antiplatelet therapy (Stratum 2) if there was an indication for anticoagulation or not, respectively. The primary endpoint was the composite of death, myocardial infarction, stroke or transient ischaemic attack, systemic embolism, intracardiac or bioprosthesis thrombosis, deep vein thrombosis or pulmonary embolism, and life-threatening, disabling, or major bleeding over 1-year follow-up. The primary safety endpoint was major, disabling, or life-threatening bleeding. The primary outcome occurred in 138 (18.4%) and 151 (20.1%) patients receiving apixaban or standard of care, respectively [hazard ratio (HR) 0.92; 95% confidence interval (CI) 0.73-1.16] and there was no evidence of interaction between treatment and stratum (Pinteraction = 0.57). The primary safety endpoint was similar in both groups (HR 1.02; 95% CI 0.72-1.44). In Stratum 1 (n = 451), an exploratory analysis showed no difference for all endpoints between apixaban and VKA. In Stratum 2 (n = 1049), the primary outcome and primary safety endpoint did not differ, but obstructive valve thrombosis was reduced with apixaban vs. antiplatelet therapy (HR 0.19; 95% CI 0.08-0.46), while a signal of higher non-cardiovascular mortality was observed with apixaban.After TAVI, apixaban was not superior to the standard of care, irrespective of an indication for oral anticoagulation.

An association of aspirin with clopidogrel is the reference treatment for prevention of thrombosis secondary to coronary angioplasty [1Mehta S.R. Yusuf S. Peters R.J. Bertrand M.E. Lewis B.S. Natarajan M.K. Malmberg K. Rupprecht H. Zhao F. Chrolavicius S. Copland I. Fox K.A. Effects of pretreatment with clopidogrel and aspirin followed by long‐term therapy in patients undergoing percutaneous coronary intervention: the PCI‐CURE study.Lancet. 2001; 358: 527-33Abstract Full Text Full Text PDF PubMed Scopus (0) Google Scholar]. Clopidogrel inhibits platelet activation by blocking the P2Y12 platelet receptor, activation of which is associated with dephosphorylation of intraplatelet vasodilator‐stimulated phosphoprotein (VASP). VASP phosphorylation provides an index of platelet reactivity to clopidogrel, which varies between individuals: the greater it is the more frequently thrombosis occurs [2Barragan P. Bouvier J.L. Roquebert P.O. Macaluso G. Commeau P. Comet B. Lafont A. Camoin L. Walter U. Eigenthaler M. Resistance to thienopyridines: clinical detection of coronary stent thrombosis by monitoring of vasodilator‐stimulated phosphoprotein phosphorylation.Catheter Cardiovasc Interv. 2003; 59: 295-302Crossref PubMed Scopus (0) Google Scholar]. Clopidogrel is a prodrug, activated by cytochrome 2C19. We investigated whether interactions with other substances could account for the observed variation in biological response to clopidogrel. The VASP test was performed on 105 consecutive patients (mean age: 63.7 years, 61% male) receiving aspirin + clopidogrel bitherapy in a context of high‐risk coronary angioplasty. The mean VASP test result, performed at least 48 h after initiation of treatment, was 52.2 ± 18.7, with a range of 6–89. Platelet response was analyzed by Mann–Whitney U‐test according to the different standard accompanying treatments: no significant differences were found for statins, angiotensin‐converting enzyme inhibitors, angiotensin II receptor antagonist and beta blockers. Conversely, proton pump inhibitors (PPI) users had significantly higher VASP values than non‐users [61.4 ± 23.2 (n = 24), vs. 49.5 ± 16.3 (n = 81) respectively, P = 0.007]. These results are the first to show an association between PPI treatment and diminished biological action of clopidogrel. CYP 2C19, which the 681G>A polymorphism has recently been shown to determine the response to clopidogrel [3Hulot J.S. Bura A. Villard E. Azizi M. Remones V. Goyenvalle C. Aiach M. Lechat P. Gaussem P. Cytochrome P450 2C19 loss‐of‐function polymorphism is a major determinant of clopidogrel responsiveness in healthy subjects.Blood. 2006; 13Google Scholar], is involved in both clopidogrel activation and PPI metabolism [4Furata T. Shirai N. Xiao F. Ohashi K. Ishizaki T. Effect of high‐dose lansoprazole on intragastric pH in subjects who are homozygous extensive metabolizers of cytochrome P4502C19.Clin Pharmacol Ther. 2001; 70: 484-92Crossref PubMed Scopus (0) Google Scholar]. A competitive effect of PPIs on CYP 2C19 might thus underlie clopidogrel's reduced effectiveness in patients receiving PPIs. Demonstrating an interaction between these two drugs, which are so routinely associated in cardiology, would have major implications for the management of the risk of thrombosis following angioplasty, but will require the results of a randomized study that is currently under way.

The aim of this prospective multinational registry is to assess and identify predictors of in-hospital outcome and complications of contemporary TAVI practice.The Transcatheter Valve Treatment Sentinel Pilot Registry is a prospective independent consecutive collection of individual patient data entered into a web-based case record form (CRF) or transferred from compatible national registries. A total of 4,571 patients underwent TAVI between January 2011 and May 2012 in 137 centres of 10 European countries. Average age was 81.4±7.1 years with equal representation of the two sexes. Logistic EuroSCORE (20.2±13.3), access site (femoral approach: 74.2%), type of anaesthesia and duration of hospital stay (9.3±8.1 days) showed wide variations among the participating countries. In-hospital mortality (7.4%), stroke (1.8%), myocardial infarction (0.9%), major vascular complications (3.1%) were similar in the SAPIEN XT and CoreValve (p=0.15). Mortality was lower in transfemoral (5.9%) than in transapical (12.8%) and other access routes (9.7%; p<0.01). Advanced age, high logistic EuroSCORE, pre-procedural ≥grade 2 mitral regurgitation and deployment failure predicted higher mortality at multivariate analysis.Increased operator experience and the refinement of valve types and delivery catheters may explain the lower rate of mortality, stroke and vascular complications than in historical studies and registries.

Coronary artery bifurcations present a harmonious asymmetric geometry that is fractal in nature. Interventional treatment of bifurcation lesions is a major technical issue. The present study is aimed at a precise quantification of this geometry in the hope of deriving a formulation that would be simple to calculate.Forty seven patients with strictly normal coronarographic results obtained ahead of valve replacement were enrolled, and 27 of these underwent IVUS examination to confirm that their arteries were indeed normal. Three reference diameters were measured: those of the mother vessel (Dm) and of either daughter vessel (Dd1, Dd2). One hundred and seventy-three bifurcations were thus subjected to quantitative analysis. The mean diameter of the mother vessels was 3.33+/-0.94 mm, of the major daughter vessels 2.70+/-0.77 mm, and of the minor daughter vessels 2.23+/-0.68 mm. The ratio R=Dm/(Dd1+Dd2) of mother-vessel diameter to the sum of the two daughter-vessel diameters was 3.39/(2.708+2.236)=0.678. This ratio held at all levels of bifurcation: i.e., whatever diameter the mother vessel.The study confirmed the fractal nature of the geometry of the epicardial coronary artery tree, and gave a simple and accurate fractal ratio between the diameters of the mother and two daughter vessels such that Dm=0.678 (Dd1+Dd2). This makes it easy to calculate the precise diameter of any of the three vessels when those of the other two are known.

Clopidogrel requires metabolic activation by cytochrome P450 2C19 (CYP2C19). Proton pump inhibitors (PPIs) that inhibit CYP2C19 are commonly coadministered with clopidogrel to reduce the risk of gastrointestinal bleeding. This analysis compares treatment outcomes for patients in the French Registry of Acute ST-Elevation and Non-ST-Elevation Myocardial Infarction (FAST-MI) who did or did not receive clopidogrel and/or PPIs.The FAST-MI registry included 3670 patients (2744 clopidogrel- and PPI-naïve patients) presenting with definite MI. Patients were categorized according to use of clopidogrel and/or PPI within 48 hours after hospital admission. PPI use was not associated with an increased risk for any of the main in-hospital events (in-hospital survival, reinfarction, stroke, bleeding, and transfusion). Likewise, PPI treatment was not an independent predictor of 1-year survival (hazard ratio, 0.97; 95% confidence interval [CI], 0.87 to 1.08; P=0.57) or 1-year MI, stroke, or death (hazard ratio, 0.98; 95% CI, 0.90 to 1.08; P=0.72). No differences were seen when the type of PPI or CYP2C19 genotype was taken into account. In the propensity-matched cohorts, the odds ratios for major in-hospital events in PPI versus no PPI were 0.29 (95% CI, 0.06 to 1.44) and 1.70 (95% CI, 0.10 to 30.3) for patients with 1 and 2 variant alleles, respectively. Similarly, the hazard ratio for 1-year events in hospital survivors was 0.68 (95% CI, 0.26 to 1.79) and 0.55 (95% CI, 0.06 to 5.30), respectively.PPI use was not associated with an increased risk of cardiovascular events or mortality in patients administered clopidogrel for recent MI, whatever the CYP2C19 genotype, although harm could not be formally excluded in patients with 2 loss-of-function alleles.

To evaluate multislice computed tomography (MSCT) as an alternative to coronary angiography, we prospectively studied its diagnostic accuracy for the detection of significant coronary artery lesions in patients with significant aortic valve stenosis undergoing valve surgery.In patients with aortic valve stenosis, coronary angiography is still recommended before surgery. Multislice computed tomography is a promising noninvasive technique for the detection of significant coronary artery lesions.Fifty-five consecutive patients scheduled for coronary angiography in the preoperative assessment of aortic valve stenosis underwent 16-slice MSCT 24 h before coronary angiography. We analyzed coronary lesions, image quality, and arterial calcium score.The sensitivity of the MSCT-based strategy in detecting significant stenosis was 100%, and its specificity 80%. The positive and negative predictive values were respectively 55% and 100%. For calcium scores <1,000 (77% of patients), MSCT detected all patients without coronary artery disease, enabling conventional coronary angiography to be avoided in 35 of 55 cases (80%). For calcium scores >1,000, MSCT enabled conventional coronary angiography to be avoided in only 6% of cases, either because significant stenosis was found with a possible indication of revascularization, or because the examination was not interpretable.The results of this initial experience in relatively few patients suggest that MSCT-based coronary angiography may serve as an alternative to invasive coronary angiography to rule out significant coronary artery disease in patients scheduled for elective aortic valve replacement. Larger studies are necessary to fully explore the potential of coronary MSCT to improve preoperative risk stratification.

Background— Transcatheter aortic valve implantation (TAVI) performed under local anesthesia (LA) is becoming increasingly common. We aimed to compare the clinical outcomes in patients who underwent transfemoral-TAVI under general anesthesia (GA) and LA. Methods and Results— Data from 2326 patients in the French Aortic National CoreValve and Edwards 2 (FRANCE 2) registry who underwent transfemoral-TAVI were analyzed. During the study period, the percentage of LA procedures increased gradually from 14% in January 2010 to 59% in October 2011. The clinical outcomes for GA (n=1377) and LA (n=949) were compared. Numerous baseline characteristics differed between the 2 groups, and the use of transesophageal echocardiographic guidance was more common in GA than in LA (76.3% versus 16.9%; P &lt;0.001). Device success and cumulative 30-day survival rates were similar in the 2 groups (97.6% versus 97.0%; P =0.41 and 91.6% versus 91.3%; P =0.69, respectively), whereas the incidence of postprocedural aortic regurgitation≥mild was significantly lower in GA than in LA (15.0% versus 19.1%; P =0.015). The groups were also analyzed using a propensity-matching model, including transesophageal echocardiographic usage (GA [n=401] versus LA [n=401]). This model indicated that there were no significant differences between the 2 groups in the rates of 30-day survival (GA [91.4%] versus LA [89.3%]; P =0.27] and postprocedural aortic regurgitation≥mild (GA [12.7%] versus LA [16.2%]; P =0.19). Conclusions— The less invasive transfemoral-TAVI under LA is preferred in clinical settings and seems to be acceptable; however, the higher incidence of postprocedural aortic regurgitation is emphasized. Therapeutic efforts should be made to reduce such complications during transfemoral-TAVI under LA.

Mitral regurgitation (MR) is a common entity in patients with aortic stenosis undergoing transcatheter aortic valve replacement (TAVR), but its influence on outcomes remains controversial. The purpose of this meta-analysis was to assess the clinical impact of and changes in significant (moderate-severe) MR in patients undergoing TAVR, overall and according to valve design (self-expandable (SEV) vs balloon-expandable (BEV)).All national registries and randomised trials were pooled using meta-analytical guidelines to establish the impact of moderate-severe MR on mortality after TAVR. Studies reporting changes in MR after TAVR on an individual level were electronically searched and used for the analysis.Eight studies including 8015 patients (SEV: 3474 patients; BEV: 4492 patients) were included in the analysis. The overall 30-day and 1-year mortality was increased in patients with significant MR (OR 1.49, 95% CI 1.16 to 1.92; HR 1.32, 95% CI 1.12 to 1.55, respectively), but a significant heterogeneity across studies was observed (p<0.05). The impact of MR on mortality was not different between SEV and BEV in meta-regression analysis for 30-day (p=0.360) and 1-year (p=0.388) mortality. Changes in MR over time were evaluated in nine studies including 1278 patients. Moderate-severe MR (SEV: 326 patients; BEV: 192 patients) improved in 50.5% of the patients at a median follow-up of 180 (30-360) days after TAVR, and the degree of improvement was greater in patients who had received a BEV (66.7% vs 40.8% in the SEV group, p=0.001).Concomitant moderate-severe MR was associated with increased early and late mortality following TAVR. A significant improvement in MR severity was detected in half of the patients following TAVR, and the degree of improvement was greater in those patients who had received a BEV.

We sought to determine whether the optimal dual antiplatelet therapy (DAPT) duration after drug-eluting stent (DES) placement varies according to clinical presentation.We performed an individual patient data pairwise and network meta-analysis comparing short-term (≤6-months) versus long-term (1-year) DAPT as well as 3-month vs. 6-month vs 1-year DAPT. The primary study outcome was the 1-year composite risk of myocardial infarction (MI) or definite/probable stent thrombosis (ST). Six trials were included in which DAPT after DES consisted of aspirin and clopidogrel. Among 11 473 randomized patients 6714 (58.5%) had stable CAD and 4758 (41.5%) presented with acute coronary syndrome (ACS), the majority of whom (67.0%) had unstable angina. In ACS patients, ≤6-month DAPT was associated with non-significantly higher 1-year rates of MI or ST compared with 1-year DAPT (Hazard Ratio (HR) 1.48, 95% Confidence interval (CI) 0.98-2.22; P = 0.059), whereas in stable patients rates of MI and ST were similar between the two DAPT strategies (HR 0.93, 95%CI 0.65-1.35; P = 0.71; Pinteraction = 0.09). By network meta-analysis, 3-month DAPT, but not 6-month DAPT, was associated with higher rates of MI or ST in ACS, whereas no significant differences were apparent in stable patients. Short DAPT was associated with lower rates of major bleeding compared with 1-year DAPT, irrespective of clinical presentation. All-cause mortality was not significantly different with short vs. long DAPT in both patients with stable CAD and ACS.Optimal DAPT duration after DES differs according to clinical presentation. In the present meta-analysis, despite the fact that most enrolled ACS patients were relatively low risk, 3-month DAPT was associated with increased ischaemic risk, whereas 3-month DAPT appeared safe in stable CAD. Prolonged DAPT increases bleeding regardless of clinical presentation. Further study is required to identify the optimal duration of DAPT after DES in individual patients based on their relative ischaemic and bleeding risks.

Although some randomized controlled trials (RCTs) and meta-analyses have suggested that prolonged dual-antiplatelet therapy (DAPT) may be associated with increased mortality, the mechanistic underpinnings of this association remain unclear. The aim of this study was to analyze the associations among bleeding, mortality, and DAPT duration after drug-eluting stent implantation in a meta-analysis of RCTs. RCTs comparing different DAPT durations after drug-eluting stent placement were sought through the MEDLINE, Embase, and Cochrane databases and the proceedings of international meetings. Deaths were considered possibly bleeding related if occurring within 1 year of the episodes of bleeding. Primary analysis was by intention-to-treat. Secondary analysis was performed in a modified intention-to-treat population in which events occurring when all patients were on DAPT were excluded. Individual patient data were obtained for 6 RCTs, and aggregate data were available for 12 RCTs. Patients with bleeding had significantly higher rates of mortality compared with those without, and in a time-adjusted multivariate analysis, bleeding was an independent predictor of mortality occurring within 1 year of the bleeding episode (hazard ratio: 6.93; 95% confidence interval: 4.53 to 10.60; p < 0.0001). Shorter DAPT was associated with lower rates of all-cause death compared with longer DAPT (hazard ratio: 0.85; 95% confidence interval: 0.73 to 1.00; p = 0.05), which was driven by lower rates of bleeding-related deaths with shorter DAPT compared with prolonged DAPT (hazard ratio: 0.65; 95% confidence interval: 0.43 to 0.99; p = 0.04). Mortality unrelated to bleeding was comparable between the 2 groups. Similar results were apparent in the modified intention-to-treat population. Bleeding was strongly associated with the occurrence of mortality within 1 year after the bleeding event. Shorter compared with longer DAPT was associated with lower risk for bleeding-related death, a finding that may underlie the lower all-cause mortality with shorter DAPT in the RCTs of different DAPT durations after DES.

Background Prolonged dual anti-platelet therapy (DAPT) is intended to reduce ischaemic events, at the cost of an increased bleeding risk in patients undergoing percutaneous coronary intervention (PCI). In this study, we evaluated whether race influences the ischaemia/bleeding risk trade-off. Methods We searched for randomized clinical trials (RCTs) comparing DAPT duration after PCI. To compare the benefit or harm between DAPT duration by race, individual patient-level landmark meta-analysis was performed after discontinuation of the shorter duration DAPT group in each RCT. The primary ischaemic endpoint was major adverse cardiac events (MACEs), and the primary bleeding endpoint was major bleeding events (clinicaltrials.gov NCT03338335). Results Seven RCTs including 16,518 patients (8,605 East Asians, 7,913 non-East Asians) were pooled. MACE occurred more frequently in non-East Asians (0.8% vs. 1.8%, p &lt; 0.001), while major bleeding events occurred more frequently in East Asians (0.6% vs. 0.3%, p = 0.001). In Cox proportional hazards model, prolonged DAPT significantly increased the risk of major bleeding in East Asians (hazard ratio [HR], 2.843, 95% confidence interval [CI], 1.474–5.152, p = 0.002), but not in non-East Asians (HR, 1.375, 95% CI, 0.523–3.616, p = 0.523). East Asians had a higher median probability risk ratio of bleeding to ischaemia (0.66 vs. 0.15), and the proportion of patients with higher probability of bleeding than ischaemia was significantly higher in East Asians (32.3% vs. 0.4%, p &lt; 0.001). Conclusion We suggest that the ischaemia/bleeding trade-off may be different between East Asians and non-East Asians. In East Asians, prolonged DAPT may have no effect in reducing the ischaemic risk, while significantly increases the bleeding risk.

Background: The FRANCE-2 registry (French Aortic National Corevalve and Edwards) previously reported good early- and medium-term clinical and echocardiographic efficacy for transcatheter aortic valve replacement. We here report 5-year follow-up results from the registry. Methods: The registry includes all consecutive patients undergoing transcatheter aortic valve replacement for severe aortic stenosis in France. Follow-up is scheduled at 30 days, 6 months, then annually from 1 to 5 years. Clinical events were defined according to the Valve Academic Research Consortium criteria, and hemodynamic structural valve deterioration (SVD) was defined according to the consensus statement by the European Association of Percutaneous Cardiovascular Interventions. Results: Between January 2010 and January 2012, 4201 patients were enrolled in 34 centers. Five-year vital status was available for 95.5% of patients; 88.1% had clinical evaluation or died. Overall, at 5 years, all-cause mortality was 60.8% (n=2478; 95% CI, 59.3% to 62.3%). The majority of cardiovascular events occurred in the first month after valve implantation, and incidence remained low thereafter, at &lt;2% per year up to 5 years, except for heart failure. The rate of heart failure was 14.3% at 1 year, then decreased over time to &lt;5% per year. In cumulative incidence function, the rates of severe SVD and moderate/severe SVD at 5 years were 2.5% and 13.3%, respectively. Mortality did not differ between patients with or without severe SVD (hazard ratio, 0.71; 95% CI, 0.47–1.07; P =0.1). Finally, in the population of patients with severe SVD, 1 patient (1.7%) experienced a stroke, and 8 patients presented ≥1 heart failure event (13.3%). Conclusions: The 5-year follow-up results of the FRANCE-2 registry represent the largest long-term data set available in a high-risk population. In surviving patients, the low rate of clinical events and the low level of SVD after 1 year support the long-term efficacy of transcatheter aortic valve replacement in both types of transcatheter prosthesis featuring in the registry.

Pulmonary hypertension (PH) is associated with poor prognosis in patients with severe aortic stenosis. The aim of this multicenter study was to describe clinical outcome after transcatheter aortic valve implantation.The FRANCE 2 Registry included all patients undergoing transcatheter aortic valve implantation in France in 2010 and 2011. Patients were divided into 3 groups depending on systolic pulmonary artery pressure (sPAP) estimated in transthoracic echocardiography: group I, sPAP <40 mm Hg (no PH); group II, sPAP 40 to 59 mm Hg (mild-to-moderate PH); and group III, sPAP ≥60 mm Hg (severe PH). Patients were followed up for 1 year. A total of 2435 patients whose pre-transcatheter aortic valve implantation sPAP was reported were included. A total of 845 were in group I (34.7%), 1112 in group II (45.7%), and 478 in group III (19.6%). Procedural success, early complications, and 30-day mortality were statistically similar across sPAP groups. One-year mortality was higher in groups II and III (group I, 22%; group II, 28%; and group III, 28%; P=0.032). Mild-to-moderate and severe PH were identified as an independent factor of all-cause mortality. The major adverse cardiovascular event rates did not differ according to sPAP. New York Health Association functional class improved significantly in all groups.PH (sPAP ≥40 mm Hg) in patients with aortic stenosis undergoing transcatheter aortic valve implantation was associated with increased 1-year mortality especially when severe (sPAP ≥60 mm Hg) but not with increased 30-day mortality, and functional status was significantly improved regardless of PAP level.

Transcatheter aortic valve replacement (TAVR) has revolutionized management of high-risk patients with severe aortic stenosis. However, survival and the incidence of severe complications have been assessed in relatively small populations and/or with limited follow-up. This report details late clinical outcome and its determinants in the FRANCE-2 (FRench Aortic National CoreValve and Edwards) registry. The FRANCE-2 registry prospectively included all TAVRs performed in France. Follow-up was scheduled at 30 days, at 6 months, and annually from 1 to 5 years. Standardized VARC (Valve Academic Research Consortium) outcome definitions were used. A total of 4,201 patients were enrolled between January 2010 and January 2012 in 34 centers. Approaches were transarterial (transfemoral 73%, transapical 18%, subclavian 6%, and transaortic or transcarotid 3%) or, in 18% of patients, transapical. Median follow-up was 3.8 years. Vital status was available for 97.2% of patients at 3 years. The 3-year all-cause mortality was 42.0% and cardiovascular mortality was 17.5%. In a multivariate model, predictors of 3-year all-cause mortality were male sex (p < 0.001), low body mass index, (p < 0.001), atrial fibrillation (p < 0.001), dialysis (p < 0.001), New York Heart Association functional class III or IV (p < 0.001), higher logistic EuroSCORE (p < 0.001), transapical or subclavian approach (p < 0.001 for both vs. transfemoral approach), need for permanent pacemaker implantation (p = 0.02), and post-implant periprosthetic aortic regurgitation grade ≥2 of 4 (p < 0.001). Severe events according to VARC criteria occurred mainly during the first month and subsequently in <2% of patients/year. Mean gradient, valve area, and residual aortic regurgitation were stable during follow-up. The FRANCE-2 registry represents the largest database available on late results of TAVR. Late mortality is largely related to noncardiac causes. Incidence rates of severe events are low after the first month. Valve performance remains stable over time.

The aim of this study was to determine baseline characteristics and clinical outcomes of patients with pre-existing atrial fibrillation (AF) and of patients who presented with new-onset AF after transcatheter aortic valve implantation (TAVI). Little is known regarding the impact of AF after TAVI. The FRANCE-2 registry included all patients undergoing TAVI (N = 3,933) in France in 2010 and 2011. New-onset AF was defined as the occurrence of AF post-procedure in a patient with no documented history of AF. AF was documented before TAVI in 25.8% of patients. New-onset AF was observed in 174 patients after TAVI among patients without a history of pre-existing AF (6.0%). At 1 year, the rates of all-cause death (26.5 vs. 16.6%, respectively; p < 0.001) and cardiovascular death (11.5 vs. 7.8%, respectively; p < 0.001) were significantly higher in patients with pre-existing AF compared with those without AF. Rehospitalization for worsening heart failure and New York Heart Association functional class was also higher in patients with pre-existing AF versus those without, resulting in a higher rate of combined efficacy endpoint in this group (p < 0.001). A history of stroke, surgical (nontransfemoral) approach, cardiological, and hemorrhagic procedure-related events were all independently related to the occurrence of new-onset post-procedural AF. New-onset AF in patients without pre-existing AF was associated with a higher rate of combined safety endpoint at 30 days (p < 0.001) and a higher rate of both all-cause death and combined efficacy endpoint at 1 year (p = 0.003 and p = 0.02, respectively). Pre-existing and new-onset AF are both associated with higher mortality and morbidity after TAVI.

Few randomized trials have compared bioprostheses for transcatheter aortic valve replacement, and no trials have compared bioprostheses with supra-annular design. The SCOPE 2 trial (Safety and Efficacy Comparison of Two TAVI Systems in a Prospective Randomized Evaluation 2) was designed to compare the clinical outcomes of the ACURATE neo and CoreValve Evolut bioprostheses for transcatheter aortic valve replacement.SCOPE 2 was a randomized trial performed at 23 centers in 6 countries between April 2017 and April 2019. Patients ≥75 years old with an indication for transfemoral transcatheter aortic valve replacement as agreed by the heart team were randomly assigned to receive treatment with either the ACURATE neo (n=398) or the CoreValve Evolut bioprostheses (n=398). The primary end point, powered for noninferiority of the ACURATE neo bioprosthesis, was all-cause death or stroke at 1 year. The key secondary end point, powered for superiority of the ACURATE neo bioprosthesis, was new permanent pacemaker implantation at 30 days.Among 796 randomized patients (mean age, 83.2±4.3 years; mean Society of Thoracic Surgeons Predicted Risk of Mortality score, 4.6±2.9%), clinical follow-up information was available for 778 (98%) patients. Within 1 year, the primary end point occurred in 15.8% of patients in the ACURATE neo group and in 13.9% of patients in the CoreValve Evolut group (absolute risk difference, 1.8%, upper 1-sided 95% confidence limit, 6.1%; P=0.0549 for noninferiority). The 30-day rates of new permanent pacemaker implantation were 10.5% in the ACURATE neo group and 18.0% in the CoreValve Evolut group (absolute risk difference, -7.5% [95% CI, -12.4 to -2.60]; P=0.0027). No significant differences were observed in the components of the primary end point. Cardiac death at 30 days (2.8% versus 0.8%; P=0.03) and 1 year (8.4% versus 3.9%; P=0.01), and moderate or severe aortic regurgitation at 30 days (10% versus 3%; P=0.002) were significantly increased in the ACURATE neo group.Transfemoral transcatheter aortic valve replacement with the self-expanding ACURATE neo did not meet noninferiority compared with the self-expanding CoreValve Evolut in terms of all-cause death or stroke at 1 year, and it was associated with a lower incidence of new permanent pacemaker implantation. In secondary analyses, the ACURATE neo was associated with more moderate or severe aortic regurgitation at 30 days and cardiac death at 30 days and 1 year.

Dual antiplatelet therapy is commonly used in patients undergoing transcatheter aortic valve implantation (TAVI), but the optimal antiplatelet regimen is uncertain and remains to be determined. The objective of this study was to compare 2 strategies of antiplatelet therapy in patients undergoing TAVI. A strategy using monoantiplatelet therapy (group A, n = 164) was prospectively compared with a strategy using dual antiplatelet therapy (group B, n = 128) in 292 consecutive patients undergoing TAVI. The primary end point was a combination of mortality, major stroke, life-threatening bleeding (LTB), myocardial infarction, and major vascular complications at 30 days. All adverse events were adjudicated according to the Valve Academic Research Consortium. The primary end point occurred in 22 patients (13.4%) in the group A and in 30 patients (23.4%) in the group B (hazard ratio 0.51, 95% confidence interval 0.28 to 0.94, p = 0.026). LTB (3.7% vs 12.5%, p = 0.005) and major bleedings (2.4% vs 13.3%, p <0.0001) occurred less frequently in the group A, whereas the incidence of stroke (1.2% vs 4.7%, p = 0.14) and myocardial infarction (1.2% vs 0.8%, p = 1.0) was not significantly different between the 2 groups. The benefit of a strategy using mono versus dual antiplatelet therapy persisted after multivariate adjustment and propensity score analysis (hazard ratio 0.53, 95% confidence interval 0.28 to 0.95, p = 0.033). In conclusion, a strategy using mono versus dual antiplatelet therapy in patients undergoing TAVI reduces LTB and major bleedings without increasing the risk of stroke and myocardial infarction. The results of our study question the justification of dual antiplatelet therapy and require confirmation in a randomized trial.

The optimal antithrombotic treatment after transcatheter aortic valve replacement (TAVR) remains a matter of debate. Although dual antiplatelet therapy is recommended, single antiplatelet therapy or oral anticoagulation is frequently used according to the patient profile. Whether this approach may affect clinical outcome is unknown.FRANCE TAVI (French Transcatheter Aortic Valve Implantation) is a prospective, multicenter, nationwide French registry. The study objectives were to identify independent correlates of long-term all-cause mortality and early bioprosthetic valve dysfunction (BVD), defined as increased prosthetic gradient ≥10 mm Hg or new gradient ≥20 mm Hg.To account for missing values, multiple imputations were performed. Stepwise multivariable Cox regression and logistic regression were used for all-cause mortality and bioprosthesis valve dysfunction was used, respectively. Sensitivity analysis retaining only patients with complete data were also performed.Of 12,804 patients included in the registry between January 1, 2013, and December 31, 2015, a total of 11,469 (mean ± SE age: 82.8 ± 0.07 years; logistic European System for Cardiac Operative Risk Evaluation: 17.8 ± 0.1%; mean duration of follow-up: 495 ± 3.5 days) were alive at discharge with known antithrombotic treatment and were analyzed for mortality. A total of 2,555 patients had at least 2 echocardiographic evaluations and were eligible for BVD assessment. One-third of patients had a history of atrial fibrillation, and the same proportion had oral anticoagulation at discharge (n = 3,836). Neither aspirin nor clopidogrel was independently associated with mortality. Male sex (adjusted hazard ratio [aHR]: 1.63; 95% confidence interval [CI]: 1.44 to 1.84; p < 0.001), history of atrial fibrillation (aHR: 1.41; 95% CI: 1.23 to 1.62; p < 0.001), and chronic renal failure (aHR: 1.37; 95% CI: 1.23 to 1.53; p < 0.001) were the strongest independent correlates of mortality. Anticoagulation at discharge (adjusted odds ratio [aOR]: 0.54; 95% CI: 0.35 to 0.82; p = 0.005) and a nonfemoral approach (aOR: 0.53; 95% CI: 0.28 to 1.02; p = 0.049) were independently associated with lower rates of BVD, whereas chronic renal failure (aOR: 1.46; 95% CI: 1.03 to 2.08; p = 0.034) and prosthesis size ≤23 mm (aOR: 3.43; 95% CI: 2.41 to 4.89; p < 0.001) yielded higher risk of BVD.Sex, renal failure, and atrial fibrillation affected mortality the most at the 3-year follow-up. In contrast, anticoagulation (mostly given for atrial fibrillation) decreased the risk of BVD after TAVR.

The FAST-MI programme, consisting of 1-month surveys of patients admitted to hospital for acute myocardial infarction (AMI) in France, has run since 2005. To gather data on the characteristics, management and outcomes of patients hospitalized for AMI at the end of 2015 in France and to provide comparisons with the previous surveys. Consecutive adults with ST-segment elevation myocardial infarction (STEMI) or non-ST-segment-elevation myocardial infarction (NSTEMI) with symptom onset ≤48 hours were included over a 1-month period, with a possible extension of recruitment for 1 additional month. Patients with AMI following cardiovascular procedures were excluded. In all, 204 centres participated in the survey (114 community hospitals, 40 academic, 48 private clinics, 2 army hospitals), representing 78% of French centres managing AMI patients. Inclusion started from 5 October 2015. Data were collected on-site from source files by external research technicians, using an electronic case record form with automatic quality checks. Centralized biology was organized in voluntary centres to collect RNA and DNA samples, serum and stools. Long-term follow-up was organized centrally with interrogation of municipal registry offices, physicians and by direct contact with the patients or their families. A total of 5291 patients were included over the entire recruitment period, with 3813 included during the first month (STEMI: 49%, NSTEMI: 51%). Mean age was 66 ± 14 years, 29% were ≥ 75 years of age, 28% were women; 80% presented with typical chest pain. In STEMI patients, 6% received intravenous fibrinolysis and 71% underwent primary PCI. The hospital death rate was 2.7% (STEMI: 2.8%, NSTEMI: 2.5%). Recruitment was in line with expectations and the first data show that management has continued to evolve since the 2010 survey, with continued improvement in hospital outcomes. Le programme FAST-MI est constitué d’enquêtes quinquennales d’une durée d’un mois, collectant les données des patients hospitalisés pour un infarctus du myocarde (IDM) en France depuis 2005. Collecter des données sur les caractéristiques, la prise en charge, et le devenir des patients hospitalisés pour IDM à la fin de 2015 en France, et comparer ces données à celles des enquêtes précédentes. Tous les patients adultes hospitalisés pour un IDM avec ou sans sus-décalage de ST évoluant depuis moins de 48 heures ont été inclus consécutivement pendant une période d’un mois, avec possibilité d’extension jusqu’à un mois supplémentaire. Les patients ayant présenté un IDM à la suite d’une intervention cardiovasculaire ont été exclus. En tout, 204 centres ont participé (114 hôpitaux publics non académiques, 40 CHU, 48 cliniques privées et 2 hôpitaux d’instruction des armées), soit 78 % des institutions prenant en charge des patients atteints d’infarctus. La période d’inclusion a débuté le 5 octobre 2015. Les données ont été collectées sur des cahiers d’observation informatisés avec contrôles de qualité automatisés. Une biobanque a été constituée pour collecter des échantillons d’ADN, ARN, sérum et selles. Un suivi à long terme centralisé est organisé avec interrogation des registres d’état civil, contact des médecins traitants et cardiologues et contact direct des patients ou de leurs familles. Au total, 5291 patients ont été inclus, dont 3813 pendant le premier mois (STEMI : 49 %, NSTEMI : 51 %). La moyenne d’âge est de 66 ± 14 ans et 29 % avaient 75 ans ou plus ; 28 % étaient des femmes et 80 % avaient une douleur thoracique considérée comme typique. Parmi les patients avec infarctus avec sus-décalage, 6 % ont été traités par fibrinolyse et 71 % ont eu une angioplastie primaire. La mortalité hospitalière est de 2,7 % (infarctus avec sus-décalage : 2,8 %, infarctus sans sus-décalage : 2,5 %). Le recrutement a été conforme aux attentes et les données initiales montrent que la prise en charge initiale a continué d’évoluer depuis 2010, avec une poursuite de l’amélioration des résultats cliniques en phase aiguë.

Femoral access is the gold standard for transcatheter aortic valve replacement (TAVR). Guidelines recommend reconsidering surgery when this access is not feasible. However, alternative peripheral accesses exist, although they have not been accurately compared with femoral access. This study compared nonfemoral peripheral (n-FP) TAVR with femoral TAVR. Using the data from the national prospective French registry (FRANCE TAVI [French Transcatheter Aortic Valve Implantation]), this study compared the characteristics and outcomes of TAVR procedures according to whether they were performed through a femoral or a n-FP access, using a pre-specified propensity score−based matching between groups. Subanalysis during 2 study periods (2013 to 2015 and 2016 to 2017) and among low/intermediate-low and intermediate-high/high volume centers were performed. Among 21,611 patients, 19,995 (92.5%) underwent femoral TAVR and 1,616 (7.5%) underwent n-FP TAVR (transcarotid, n = 914 or trans-subclavian, n = 702). Patients in the n-FP access group had more severe disease (mean logistic EuroSCORE 19.95 vs. 16.95; p < 0.001), with a higher rate of peripheral vascular disease, known coronary artery disease, chronic pulmonary disease, and renal failure. After matching, there was no difference in the rate of post-procedural death and complications according to access site, except for a 2-fold lower rate of major vascular complications (odds ratio: 0.45; 95% confidence interval: 0.21 to 0.93; p = 0.032) and unplanned vascular repairs (odds ratio: 0.41; 95% confidence interval: 0.29 to 0.59; p < 0.001) in those who underwent n-FP access. The comparison of outcomes provided similar results during the second study period and in intermediate-high/high volume centers. n-FP TAVR is associated with similar outcomes compared with femoral peripheral TAVR, except for a 2-fold lower rate of major vascular complications and unplanned vascular repairs. n-FP TAVR may be favored over surgery in patients who are deemed ineligible for femoral TAVR and may be a safe alternative when femoral access risk is considered too high.

Transcatheter aortic valve replacement (TAVR) has emerged as an alternative to surgical aortic valve replacement (SAVR), but unbiased data regarding evolution of the treatment of patients with aortic stenosis at the nationwide level are scarce.This study sought to evaluate the number of aortic valve replacements (AVRs) performed in France, changes over time, and the effect of the adoption of TAVR.Based on a French administrative hospital-discharge database, the study collected all consecutive AVRs performed in France between 2007 and 2015.A total of 131,251 interventions were performed: 109,317 (83%) SAVR and 21,934 (17%) TAVR. AVR linearly increased (from 10,892 to 18,704; p for trend <0.0001) mainly due to a marked increase in TAVR (from 244 to 6,722; p for trend = 0.0004), whereas SAVR remained stable (from 10,892 to 11,982; p for trend = 0.18). Parallel to a decrease in the Charlson index (p for trend <0.05), SAVR and TAVR in-hospital mortality rates significantly declined (both p for trend <0.01). The number of TAVRs significantly increased in all age categories (<75, 75 to 79, 80 to 84, and ≥85 years of age; all p for trend = 0.003), but reached or even exceeded SAVR in the 2 oldest categories. Although mortality rates declined for both isolated SAVR and TAVR, it became similar or slightly lower for TAVR than for isolated SAVR in 2015 in the 3 oldest age categories even if it did not reach statistical significance (p = 0.66, p = 0.47, and p = 0.06, respectively).The number of AVRs markedly increased in France between 2007 and 2015 due to the wide adoption of TAVR, which represented one-third of all AVRs in 2015. Patients' profile improved, suggesting that patients are referred earlier, and in-hospital mortality declined in all AVR subsets. Despite a worse clinical profile, the immediate outcome of TAVR compared favorably to isolated SAVR in patients >75 years of age. The results may have major implications for clinical practice and policymakers.

To derive and validate a readily useable risk score to identify patients at high-risk of in-hospital ST-segment elevation myocardial infarction (STEMI)-related cardiogenic shock (CS). In all, 6838 patients without CS on admission and treated by primary percutaneous coronary intervention (pPCI), included in the Observatoire Régional Breton sur l’Infarctus (ORBI), served as a derivation cohort, and 2208 patients included in the obseRvatoire des Infarctus de Côte-d’Or (RICO) constituted the external validation cohort. Stepwise multivariable logistic regression was used to build the score. Eleven variables were independently associated with the development of in-hospital CS: age >70 years, prior stroke/transient ischaemic attack, cardiac arrest upon admission, anterior STEMI, first medical contact-to-pPCI delay >90 min, Killip class, heart rate >90/min, a combination of systolic blood pressure <125 mmHg and pulse pressure <45 mmHg, glycaemia >10 mmol/L, culprit lesion of the left main coronary artery, and post-pPCI thrombolysis in myocardial infarction flow grade <3. The score derived from these variables allowed the classification of patients into four risk categories: low (0–7), low-to-intermediate (8–10), intermediate-to-high (11–12), and high (≥13). Observed in-hospital CS rates were 1.3%, 6.6%, 11.7%, and 31.8%, across the four risk categories, respectively. Validation in the RICO cohort demonstrated in-hospital CS rates of 3.1% (score 0–7), 10.6% (score 8–10), 18.1% (score 11–12), and 34.1% (score ≥13). The score demonstrated high discrimination (c-statistic of 0.84 in the derivation cohort, 0.80 in the validation cohort) and adequate calibration in both cohorts. The ORBI risk score provides a readily useable and efficient tool to identify patients at high-risk of developing CS during hospitalization following STEMI, which may aid in further risk-stratification and thus potentially facilitate pre-emptive clinical decision making.

In low-flow, low-gradient aortic stenosis (LFLG AS), the severity of left ventricular dysfunction remains a key factor in the evaluation of aortic valve replacement.To evaluate the clinical outcomes and changes in left ventricular ejection fraction (LVEF) after transcatheter aortic valve replacement (TAVR) in patients with LFLG AS and severe left ventricular dysfunction.This multicenter registry is a substudy of the True or Pseudo-Severe Aortic Stenosis-TAVI registry that included patients with classic LFLG AS, defined as a mean transvalvular gradient less than 35 mm Hg, an effective orifice area less than 1.0 cm2, and an LVEF of 40% or less. Patients were divided in groups with very low (<30%) LVEF and low (30%-40%) LVEF. Dobutamine stress echocardiography (DSE) was performed before TAVR in a subset with very low LVEF, and presence of contractile reserve was defined as an increase of 20% or more in stroke volume. Clinical outcomes were assessed at 1 and 12 months and yearly thereafter, and echocardiography was performed at 1-year follow-up. Retrospective data were collected from 2007 to 2013 and prospective data from January 2013 to March 2018. Data were analyzed from March to October 2018.Transcatheter aortic valve replacement in patients with LFLG AS.Changes in LVEF over time; periprocedural and late mortality.A total of 293 patients were included, including 128 (43.7%) with very low LVEF and 165 with low LVEF (56.3%). Their mean (SD) age was 80 (7) years, and most (214 [73.0%]) were men. The mean (SD) LVEF in the very low LVEF group was 22% (5%), compared with 37% (7%) in the low LVEF group (P < .001). There were no differences between groups in rates of periprocedural mortality and late mortality (median [interquartile range], 23 [6-38] months). Patients with very low LVEF displayed a greater increase in LVEF at the 1-year follow-up examination (mean absolute increase, 11.9% [95% CI, 8.8%-15.1%]), than the low LVEF group (3.6% [95% CI, 1.1%-6.1%]; P < .001). In 92 patients with very low LVEF who had preprocedural DSE, results showed a lack of contractile reserve in 45 (49%), but this had no effect on clinical outcomes or changes in LVEF over time.In patients with LFLG AS and severe left ventricular dysfunction, TAVR was associated with similar clinical outcomes as in counterparts with milder left ventricular dysfunction. The TAVR procedure was associated with a significant increase in LVEF, irrespective of contractile reserve. These results support TAVR for LFLG AS, irrespective of the severity of left ventricular dysfunction and DSE results.

2020 ESC Guidelines for the management of acute coronary syndromes in patients presenting without persistent ST-segment elevation

Transcatheter aortic valve replacement (TAVR) as an alternative to surgical aortic valve replacement (SAVR) has profoundly changed the management of patients with aortic valve stenosis (AS). Large unbiased nationwide data regarding TAVR implementation, impact on SAVR and their respective outcomes are scarce.Based on a French administrative hospital-discharge database, we collected data on all consecutive aortic valve replacements (AVRs) performed in France for AS between 2007 and 2019 [106 253 isolated SAVR (49%), 46 514 combined SAVR (21%), and 65 651 TAVR (30%)]. The number of AVR linearly increased between 2007 and 2019 (from 10 892 to 23 109, P for trend < 0.0001) due to a marked increase in TAVR (from 253 to 13 030, P for trend < 0.0001), while SAVR increased up to 2013 and then declined (10 892 in 2007, 12 699 in 2013, and 10 079 in 2019). The Charlson index decreased linearly for TAVR, but in two steps for SAVR (2011 and 2017). In-hospital mortality rates of both SAVR and TAVR declined (both P for trend < 0.0001) and were similar or lower for TAVR than for isolated SAVR in patients 75 years or above in the last 3 years (2017-19). Complication rates of TAVR also declined but permanent pacemaker rates remained high and length of stay substantial (16.7% and median 6 days, respectively, in 2017-19).The number of AVR has doubled in a decade and TAVR has become the dominant form of AVR in 2018. The improvement in patient profiles seems to have anticipated the demonstrated benefit of TAVR in intermediate and low-risk patients. In patients 75 years or older, TAVR should be considered as the first option. We also highlight two important areas for improvement, the high permanent pacemaker rates, and the long length of stay even in the contemporary era. Our results may have major implications for clinical practice and policymakers.

Abstract Background and Aims Mitral valve surgery and, more recently, mitral transcatheter edge-to-edge repair (TEER) are the two treatments of severe mitral regurgitation in eligible patients. Clinical comparison of both therapies remains limited by the number of patients analysed. The objective of this study was to analyse the outcomes of mitral TEER vs. isolated mitral valve surgery at a nationwide level in France. Methods Based on the French administrative hospital discharge database, the study collected information for all consecutive patients treated for mitral regurgitation with isolated TEER or isolated mitral valve surgery between 2012 and 2022. Propensity score matching was used for the analysis of outcomes. Results A total of 57 030 patients were found in the database. After matching on baseline characteristics, 2160 patients were analysed in each arm. At 3-year follow-up, TEER was associated with significantly lower incidence of cardiovascular death (hazard ratio 0.685, 95% confidence interval 0.563–0.832; P = .0001), pacemaker implantation, and stroke. Non-cardiovascular death (hazard ratio 1.562, 95% confidence interval 1.238–1.971; P = .0002), recurrent pulmonary oedema, and cardiac arrest were more frequent after TEER. No significant differences between the two groups were observed regarding all-cause death (hazard ratio 0.967, 95% confidence interval 0.835–1.118; P = .65), endocarditis, major bleeding, atrial fibrillation, and myocardial infarction. Conclusions Our results suggest that TEER for severe mitral regurgitation was associated with lower cardiovascular mortality than mitral surgery at long-term follow-up. Pacemaker implantation and stroke were less frequently observed after TEER.

The length of stay (LOS) after transcatheter aortic valve implantation (TAVI) remains extremely variable whereas early discharge has been shown to be feasible and safe. The study objective was to evaluate the efficacy and safety of an intervention aimed at reducing LOS after transfemoral TAVI.FAST-TAVI II is a prospective, multicentre, cluster, randomized, controlled study including patients with severe symptomatic aortic stenosis, who had transfemoral TAVI. The intervention consisted in a dedicated training programme to implement 10 quality of care measures to reduce LOS with an implementation phase of eight weeks. The primary endpoint was the proportion of patients discharged early within 3 days. Secondary endpoints included: LOS, 30-day mortality and 30-day incidence of readmission for cardiovascular events.During the study period, 969 patients were enrolled in the intervention group and 860 patients in the control group. Mean age was 81.9 ± 6.6 years and mean EuroSCORE II was 4.4 ± 4.5%. Early discharge was achieved in 563 (58.1%) patients in the intervention group vs. 364 (42.3%) patients in the control group (P < .0001). Median LOS was significantly reduced in the intervention group compared to the control group [3 (IQR: 3) vs. 4 days (IQR: 3), P < .0001]. Thirty-day mortality was low and similar in the two groups (0.5% vs. 0.9%, P = .30), as were 30-day readmissions (4.6% vs. 2.8%, P = .28).The intervention was simple and fast to implement, and was effective and safe to reduce LOS and increase the proportion of patients discharged early after TAVI (NCT04503655).

Research performed in Europe has driven cardiovascular device innovation. This includes, but is not limited to, percutaneous coronary intervention, cardiac imaging, transcatheter heart valve implantation, and device therapy of cardiac arrhythmias and heart failure. An important part of future medical progress involves the evolution of medical technology and the ongoing development of artificial intelligence and machine learning. There is a need to foster an environment conducive to medical technology development and validation so that Europe can continue to play a major role in device innovation while providing high standards of safety. This paper summarizes viewpoints on the topic of device innovation in cardiovascular medicine at the European Society of Cardiology Cardiovascular Round Table, a strategic forum for high-level dialogue to discuss issues related to the future of cardiovascular health in Europe. Devices are developed and improved through an iterative process throughout their lifecycle. Early feasibility studies demonstrate proof of concept and help to optimize the design of a device. If successful, this should ideally be followed by randomized clinical trials comparing novel devices vs. accepted standards of care when available and the collection of post-market real-world evidence through registries. Unfortunately, standardized procedures for feasibility studies across various device categories have not yet been implemented in Europe. Cardiovascular imaging can be used to diagnose and characterize patients for interventions to improve procedural results and to monitor devices long term after implantation. Randomized clinical trials often use cardiac imaging-based inclusion criteria, while less frequently trials randomize patients to compare the diagnostic or prognostic value of different modalities. Applications using machine learning are increasingly important, but specific regulatory standards and pathways remain in development in both Europe and the USA. Standards are also needed for smart devices and digital technologies that support device-driven biomonitoring. Changes in device regulation introduced by the European Union aim to improve clinical evidence, transparency, and safety, but they may impact the speed of innovation, access, and availability. Device development programmes including dialogue on unmet needs and advice on study designs must be driven by a community of physicians, trialists, patients, regulators, payers, and industry to ensure that patients have access to innovative care.

The purpose of this study is to report prospectively the results of six-month follow-up of permanent left ventricular (LV) based pacing in patients with severe congestive heart failure (CHF) and left bundle branch block (LBBB).Left ventricular pacing alone has been demonstrated to result in identical improvement compared to biventricular pacing (BiV) during acute hemodynamic evaluation in patients with advanced CHF and LBBB. However, to our knowledge, the clinical outcome during permanent LV pacing alone versus BiV pacing mode has not been evaluated.Pacing configuration (LV or BiV) was selected according to the physician's preference. Patient evaluation was performed at baseline and at six months.Thirty-three patients with advanced CHF and LBBB were included. Baseline characteristics of LV (18 patients) and BiV (15 patients) pacing groups were similar. During the six-month follow-up period, seven patients died three BiV and four LV). In the surviving patients at 6 months, 8 of 14 patients in the LV group and 9 of 12 in the BiV group were in New York Heart Association class I or II (p = 0.39). No significant difference was observed between the two groups in terms of objective parameters except for LV end-diastolic diameter decrease (-4.4 mm in BiV group vs. -0.7 mm in LV group; p = 0.04).At six-month follow-up, a trend toward improvement was observed in objective parameters in patients with severe CHF and LBBB following LV-based pacing. The two pacing modes (LV and BiV) were associated with almost equivalent improvement of subjective and objective parameters.

<b>Objective:</b> To analyse coronary stents with multislice spiral computed tomography (MSCT) in comparison with coronary angiography. <b>Patients and methods:</b> 310 patients referred for conventional coronary angiography underwent MSCT on the next day (16 × 0.75 mm cross section, 420 ms rotation, 110 ml contrast agent intravenously at 4 ml/s). Two independent blinded reviewers analysed the MSCT. <b>Results:</b> 143 patients had previous stenting (232 stents) and 190 (82%) of the 232 stents were detected. Intrastent lumen was interpretable in 126 (64%) of the detected stents. Lumen interpretability depended on stent diameter: for stent diameter &gt; 3 mm, 81% of lumens were interpretable, as against 51% with ⩽ 3 mm stent diameter (p &lt; 0.001). Restenosis detection likewise depended on stent diameter: with small stents (⩽ 3 mm), sensitivity and specificity of MSCT were 54% and 100%, respectively; positive and negative predictive values were 100% and 94%. For stents with &gt; 3 mm diameter, corresponding values were 86%, 100%, 100%, and 99%. <b>Conclusion:</b> 16 slice MSCT allows analysis of in-stent lumen in about half of all stented angioplasties. It performs better when stent diameter is more than 3 mm and may offer a non-invasive alternative to conventional coronary angiography for monitoring stented coronary arteries. Technical progress may improve interpretability and hence increase the yield of MSCT in this application.

Permanent left ventricular pacing has been shown to imporve the hemodynamic and clinical status of patients with severe heart failure. To pace the left ventricle, the electrode is implanted in tributaries of the coronary sinus (CS). However, the anatomy of cardiac veins with this purpose in mind has not been described in detail. Methods: One hundred consecutive patients admitted for coronary angiography had a simultaneous coronary venography performed after the injection of 8 to 10 mL of contrast material into the left coronary artery. Cardiac veins were analyzed in antero‐posterior, left anterior oblique 60±, and right anterior oblique 30± views by three different observers. The number, dimension, angulation, and position of the coronary sinus and of its tributaries were studied. Results: Two veins are consistently present: the middle cardiac vein (mean diameter 2.62 ± 1.26 mm) and the great cardiac vein (mean diameter 3.55 ± 1.24 mm). The left posterior vein(s) (LPV) (mean diameter 2.25 ± 1.2 mm) is (are) variable in number (ranging from 0 to 3), size, and angulation. The absence of LPV limits the ability to pace the left ventricle endovenously. The diameter of the vein (&lt; 2 mm) and its angulation may also complicate the insertion of the lead. Conclusion: Angiographic analysis of dimensions, tortuosity, number, and angulation of venous tributaries of the CS seems to allow the insertion of commercially available pacing leads in approximately 85% of cases. An increase in this percentage hinges on the development of new, dedicated leads.

Effects of cardiac resynchronization therapy (CRT) in patients with right ventricular pacing and congestive heart failure (CHF) have only been reported in limited series. CRT in patients with atrial fibrillation remains controversial. Patients with AV junctional ablation offer a unique opportunity to study the effects of CRT in patients with right ventricular pacing combined with atrial fibrillation. The aims of the present study were to evaluate the effects of upgrading to biventricular pacing patients with CHF, permanent atrial fibrillation, and prior ablation of the atrioventricular (AV) junction followed by conventional right ventricular pacing. We studied 16 consecutive patients with permanent atrial fibrillation treated by AV junctional ablation. After a mean follow-up of 20±19 months (6 weeks to 5 years) they were successfully upgraded to biventricular pacing for severe CHF. Parameters were prospectively evaluated at baseline and at 6 months. The 14 surviving patients at 6 months demonstrated significant improvement (P<0.02) in New York Heart Association class but the exercise test parameters remained unchanged. Cardiothoracic ratio decreased by 5% (P=0.04), end-systolic diameter by 8% (P=0.001), end-diastolic diameter by 4% (P=0.08), systolic pulmonary artery pressure by 17% (P<0.0001) and mitral regurgitation area by 40% (P<0.05). Ejection fraction increased by 17% (P=0.11) and fractional shortening by 24% (P=0.01). CRT improves left ventricular performance and functional status in patients with permanent atrial fibrillation and prior remote right ventricular pacing.

Background:The gold standard test for the diagnosis of coronary artery disease (CAD) is conventional coronary angiography (C-CAG).Lately, multislice computed tomographic coronary angiography (MSCT-CAG) demonstrated a high sensitivity and a negative predictive value for a CAD primary diagnosis when compared with C-CAG.The aim of our study is to prospectively assess the safety of ruling out CAD based solely on a normal MSCT-CAG result.Methods: From June 15, 2004, to January 20, 2006, consecutive patients initially scheduled for C-CAG for a primary diagnosis of CAD underwent MSCT-CAG instead.Patients with a highly calcified coronary network or with an abnormal or a noninterpretable MSCT-CAG result underwent secondary C-CAG and were excluded from the study.We included patients whose diagnosis of CAD was ruled out by a normal MSCT-CAG result; in those patients, C-CAG was not performed.All patients under-went further follow-up with clinical end points (death, subsequent C-CAG, and myocardial infarction).Results: In 141 patients, MSCT-CAG results were considered normal.During the follow-up period (mean, 14.7 months), those patients experienced 0% mortality, a 3.5% rate of subsequent C-CAG, and a 0.7% rate of myocardial infarction.The risks of subsequent death, new referral for C-CAG, or coronary events compare favorably with those following normal C-CAG, which were 0.4%, 4.3%, and 0.6%, respectively.Conclusions: Multislice computed tomographic CAG safely rules out CAD in patients with suspected disease and allows patients to be managed less invasively, by reducing the number in whom C-CAG has to be performed.

Gender differences in presentation, management and outcome in patients with ST-segment elevation myocardial infarction (STEMI) have been reported. To determine whether female gender is associated with higher inhospital mortality. Data from ORBI, a regional STEMI registry of 5 years’ standing, were analysed. The main data on presentation, management, inhospital outcome and prescription at discharge were compared between genders. Various adjusted hazard ratios were then calculated for inhospital mortality (women versus men). The analysis included 5000 patients (mean age 62.6 ± 13 years), with 1174 women (23.5%). Women were on average 8 years older than men, with more frequent co-morbidities. Median ischaemia time was 215 minutes (26 minutes longer in women; P < 0.05). Reperfusion strategies in women less frequently involved fibrinolysis, coronary angiography, radial access and thrombo-aspiration. Female gender, especially in patients aged < 60 years, was associated with poorer inhospital prognosis (including higher inhospital mortality: 9% vs. 4% in men; P < 0.0001), and underutilization of recommended treatments at discharge. Moreover, excess female inhospital mortality was independent of presentation, revascularization time and reperfusion strategy (hazard ratio for women 1.33, 95% confidence interval 1.01–1.76; P = 0.04). One in four patients admitted for STEMI was female, with significant differences in presentation. Female gender was associated with less-optimal treatment, both in the acute-phase and at discharge. Efforts should be made to reduce these differences, especially as female gender was independently associated with an elevated risk of inhospital mortality. Des différences liées au sexe sont signalées dans la présentation, la gestion et le pronostic des patients hospitalisés pour infarctus du myocarde avec élévation du segment ST (IDM ST+). Déterminer si le sexe féminin est associé à une mortalité intra-hospitalière plus élevée. Nous avons analysé les données d’ORBI, un registre régional de 5 ans concernant les IDM ST+. Les principales données concernant la présentation, la gestion, le devenir intra-hospitalier et le traitement à la sortie ont été comparées en fonction du sexe. Ensuite, nous avons analysé la mortalité intra-hospitalière (femmes vs hommes), avec différentes variables d’ajustement. L’analyse a inclus 5000 patients (âge moyen 62,6 ± 13 ans), dont 1174 femmes (23,5 %), qui présentaient des co-morbidités plus fréquentes et étaient 8 ans plus âgées que les hommes. Le temps d’ischémie médian était de 215 minutes (26 minutes de plus chez les femmes). Comparativement aux hommes, les stratégies de reperfusion chez les femmes comportaient moins de fibrinolyse, de coronarographie, d’accès radial et de thrombo-aspiration. Le sexe féminin, en particulier chez les moins de 60 ans, était associée à un mauvais pronostic intra-hospitalier (y compris une plus forte mortalité intra-hospitalière : 9 % contre 4 % chez les hommes ; p < 0,0001), et une sous-utilisation des traitements recommandés à la sortie. Par ailleurs, la surmortalité intra-hospitalière observée chez les femmes était indépendante de la présentation, des délais de revascularisation et des stratégies de reperfusion (hasard ratio 1,33, intervalle de confiance 95 % 1,01–1,76 ; p = 0,04). Une personne sur 4 patients admis pour un IDM ST+ est une femme, avec des différences significatives dans la présentation. Le sexe féminin est associé à un traitement moins optimal, tant à la phase aiguë qu’à la sortie d’hôpital. Un effort particulier devra être effectué afin de réduire ces différences, d’autant plus que le sexe féminin semble constituer dans cette analyse un risque indépendant de surmortalité intra-hospitalière.

The aim of this study was to assess the influence of chronic kidney disease (CKD) classification on clinical outcomes in patients undergoing transcatheter aortic valve implantation (TAVI).Data of 2,929 consecutive patients undergoing TAVI in the FRANCE 2 registry were analysed. Patients were divided into five groups: CKD 1+2, 3a, 3b, 4, and 5. Both 30-day and one-year mortality rates were significantly increased and positively correlated with CKD severity in all groups. After adjusting for significant influential confounders in a Cox regression multivariate model, CKD 4 and 5 were associated with increased risk of both 30-day mortality and one-year mortality when compared with CKD 1+2 as the reference. This higher mortality was predominantly driven by renal failure and infection in patients with CKD 4 and 5, respectively. Procedural success rate in CKD 5 was significantly lower than that in other groups. All CKD patients trended towards a higher incidence of acute kidney injury (AKI), in parallel with the degree of CKD severity.Classification of CKD stages before TAVI allows risk stratification for 30-day and one-year clinical outcomes. CKD 3b, 4 and 5 correlate with poor outcome and are considered a significant risk for TAVI.

The "obesity paradox" that patients with high body mass index (BMI) have good prognoses remains controversial. This study aimed to assess the impact of BMI on clinical outcomes in patients who underwent transcatheter aortic valve implantation (TAVI). Data from the French national TAVI registry were collected for 3,072 patients who underwent TAVI from January 2010 to October 2011. The patients were categorized into 4 groups according to BMI (kg/m(2)): underweight (<18.5 kg/m(2)), normal weight (18.5 to 25 kg/m(2)), overweight (25 to 30 kg/m(2)), and obese (>30 kg/m(2)). Thereafter, clinical outcomes were compared among the 4 groups. The BMI distribution was 3.1% (n = 95), 44.1% (n = 1,355), 34.2% (n = 1,050), and 18.6% (n = 572). Although the 4 groups greatly differed in baseline clinical background, they had similar procedural success rates (95.8%, 97.1%, 97.3%, and 95.6%, p = 0.23). Major vascular complication was significantly associated with the underweight patients after adjusting for the other potential confounders (odds ratio 2.33, 95% confidence interval 1.17 to 4.46, p = 0.016). The cumulative postoperative survival rates were increasing across the 4 groups at 30 days (83.2%, 88.9%, 91.6%, and 93.0%, p = 0.003) and 1 year (67.9%, 73.6%, 77.4%, and 80.3%, p = 0.006). In a multivariate Cox regression analysis, the overweight and obese patients were independently associated with superior cumulative survival rate at 1 year (hazard ratios 0.74 and 0.71, 95% confidence intervals 0.57 to 0.97 and 0.59 to 0.87, p = 0.050 and 0.029, respectively). In conclusion, major morbidity and 1-year mortality were less in overweight and obese patients than those classified as normal weight even in a TAVI cohort.

In the last 15 years, transcatheter aortic valve implantation (TAVI) technology has met with rapid uptake, with >350,000 procedures performed in >70 countries. Over the same period, this technique has evolved from a challenging intervention to a standardised, simple, and streamlined procedure. The purpose of this review article is to provide an overview on the rapidly changing field of TAVI therapy, exploring past achievements, current issues and future perspectives. The discussion has been subdivided into three sections: 1) the evolution of clinical and anatomical indications for TAVI, 2) the description of procedural advances and complication rate trends over time, and 3) the progressive adoption of a minimalist approach.

There is great variability for the type of anaesthesia used during TAVI, with no clear consensus coming from comparative studies or guidelines. We sought to detect regional differences in the anaesthetic management of patients undergoing transcatheter aortic valve implantation (TAVI) in Europe and to evaluate the relationship between type of anaesthesia and in-hospital and 1 year outcome.Between January 2011 and May 2012 the Sentinel European TAVI Pilot Registry enrolled 2807 patients treated via a transfemoral approach using either local (LA-group, 1095 patients, 39%) or general anaesthesia (GA-group, 1712 patients, 61%).A wide variation in LA use was evident amongst the 10 participating countries. The use of LA has increased over time (from a mean of 37.5% of procedures in the first year, to 57% in last 6 months, p<0.01). MI, major stroke as well as in-hospital death rate (7.0% LA vs 5.3% GA, p=0.053) had a similar incidence between groups, confirmed in multivariate regression analysis after adjusting for confounders. Dividing our population in tertiles according to the Log-EuroSCORE we found similar mortality under LA, whilst mortality was higher in the highest risk tertile under GA. Survival at 1 year, compared by Kaplan-Meier analysis, was similar between groups (log-rank: p=0.1505).Selection of anaesthesia appears to be more influenced by national practice and operator preference than patient characteristics. In the absence of an observed difference in outcomes for either approach, there is no compelling argument to suggest that operators and centres should change their anaesthetic practice.

Currently, several anatomical approaches and intervention sites can be used to perform transcatheter aortic valve implantations (TAVIs), often with no clinical indications for choosing one or another. While these choices can have an impact on resource consumption, no costing study is available in the European context to provide information on resource use and assist decision-making. To provide comparative data on the cost of the TAVI procedure, depending on anatomical approach and intervention site used, from a hospital perspective, and to analyze factors associated with cost of hospital stay. Multicentre national registry data were collected in 16 centres between January and October 2009. For 287 patients, a descriptive costing study and a multivariable analysis of hospital stay cost were performed. The mean cost of the TAVI procedure was € 22,876 and the mean initial hospital stay cost was € 35,164. The procedure cost, excluding valve cost, did not differ between anatomical approaches and was highest in the hybrid room and lowest in the catheterization laboratory. Factors associated with higher hospital stay cost were transapical approach, Society of Thoracic Surgeons score > 10%, warfarin use at inclusion, complications during procedure and pacemaker implantation following valve implantation. If clinical considerations do not interfere, hospital staff may find it economically favorable to opt for the catheterization laboratory and against the hybrid room. The mean hospital stay cost is higher than the tariff paid in 2011, a difference that has grown since the change in tariff in 2012, representing an economic disincentive for the uptake of TAVI in France. Il n’existe souvent aucune indication clinique permettant de faire le choix entre les différents types de salle et de voies d’abord disponibles pour effectuer une implantation de valve aortique par voie percutanée (TAVI). Bien que ces choix aient un impact en termes de consommation de ressources, aucune étude ne permet de le quantifier et d’apporter une aide à la décision dans le contexte européen. L’objectif était de fournir des données comparatives de coût de la procédure TAVI du point de vue de l’hôpital en fonction de la voie d’abord et du type de salle utilisés ainsi que de déterminer les facteurs associés au coût de séjour. Les données utilisées proviennent d’un registre national multicentrique correspondant à 16 centres et à la période allant de janvier à octobre 2009. Une étude descriptive de coût ainsi qu’une analyse multivariée du coût de séjour ont été effectuées sur une population de 287 patients. Les coûts moyens de la procédure TAVI et de l’hospitalisation initiale étaient respectivement de 22 876 € et 35 164 €. Les coûts de la procédure ne différaient pas en fonction de la voie d’abord et étaient les plus élevés en salle hybride et les moins élevés en salle de cardiologie interventionnelle. Les facteurs associés à une augmentation de coût de séjour sont la voie transapicale, un score STS supérieur à 10 %, l’utilisation d’antivitamines K à l’inclusion, la présence de complications lors de la procédure et la pose d’un pacemaker à la suite de l’intervention. Si les conditions cliniques du patient le permettent, le personnel hospitalier pourrait être amené à trouver l’utilisation de la salle de cardiologie interventionnelle économiquement plus avantageuse que celle de la salle hybride. Le coût moyen de l’hospitalisation est supérieur au tarif remboursé en 2011. Cet écart s’est amplifié depuis le changement de règle tarifaire survenue en août 2012 représentant un frein au développement de l’utilisation de TAVI en France.

The aim of this study was to analyze the incidence, impact, and predictors of cerebrovascular events (CVEs) in patients undergoing transcatheter aortic valve replacement (TAVR). Several issues remain unresolved post-TAVR, including CVEs. The FRANCE-2 (French Aortic Nation CoreValve and Edwards-2) registry prospectively included all patients who underwent TAVR in France and Monaco from January 2010 to October 2011. A total of 3,191 patients were analyzed. Six-month follow-up data were obtained. Events were adjudicated according to Valve Academic Research Consortium (VARC)-1 definition. Of the cohort, 3.98% experienced a CVE: 55% were major strokes, 14.5% minor strokes, and 30.5% transient ischemic attacks. The mean delay for CVE occurrence was 2 days (interquartile range: 0 to 7 days) with 48.5% of CVEs occurring within 2 days. There was no statistically significant difference in CVE rate with regard to the type of valve (p = 0.899) and the access route (p = 0.128). Patients with a CVE more frequently had new-onset paroxysmal atrial fibrillation (13.6% vs. 7.6%; p = 0.015). During follow-up, the unadjusted mortality rate was higher in patients with a CVE (26% vs. 16.5%; p = 0.002). By multivariate analysis, only advanced age (odds ratio: 1.05; 95% confidence interval: 1.02 to 1.08; p = 0.02) and having 2 valves implanted (odds ratio: 3.13; 95 confidence interval: 1.40 to 7.05; p = 0.006) were associated with a significant risk of CVEs. CVEs occur frequently after TAVR and are associated with an increased mortality rate. No difference exists in the CVE rate when exploring the type of valve or the access route. Advanced age and multiple valves implanted during the same procedure are predictors of CVE.

Aims Permanent pacemaker (PPM) implantation following high‐degree atrioventricular block is frequently required after transcatheter aortic valve implantation (TAVI) using CoreValve ® . Recent improvement of the delivery system (CoreValve Accutrak ® ) aimed to ease delivery and reduce the PPM rate. Our study evaluated the incidences of PPM implantation following use of CoreValve ® or CoreValve Accutrak ® and the clinical outcome of these patients. Methods and results A total of 883 patients (82 ± 7 years; 41.3% female) with severe symptomatic aortic stenosis and self‐expanding bioprosthesis implantation were included between January 2010 and October 2011 in 29 centers from the FRANCE 2 Registry. Follow‐up data were available in 833 patients. CoreValve ® and CoreValve Accutrak ® were used in 343 (41.2%) and 490 (58.8%) patients, respectively. During a mean follow‐up of 242 ± 179 days, all‐cause mortality was similar in patients with versus without PPM implantation (16.3 vs. 16.9%, P = 0.832).There was no significant difference in the PPM incidence in CoreValve ® and CoreValve Accutrak ® patients (30.4% vs. 27.5%, P = 0.846). Conclusion PPM implantation remained frequent after TAVI using CoreValve Accutrak ® . All‐cause mortality was similar in patients with or without PPM implantation. The new device failed to show a significant decrease in PPM implantation incidence after TAVI. © 2015 Wiley Periodicals, Inc.

<h3>Background</h3> High-degree atrioventricular block (HAVB) is a common complication of ST segment elevation myocardial infarction (STEMI). HAVB in STEMI is historically considered as a marker of worse outcome but overall data about HAVB in the contemporary era of mechanical reperfusion and potent antiplatelet therapies are scarce. <h3>Aim</h3> Analysing incidence, clinical correlates and impact on inhospital outcomes of HAVB in a large prospective registry (Observatoire Régional Breton sur l9Infarctus, ORBI) of modern management of STEMI with a special focus on potential differences between patients with HAVB on admission and those who developed HAVB during hospitalisation. <h3>Methods</h3> All patients enrolled in ORBI between June 2006 and December 2013 were included in the present analysis and were divided into 3 groups: patients without HAVB at any time, patients with HAVB on admission and those who developed HAVB during hospitalisation. <h3>Results</h3> A total of 6662 patients (age: 62.0 (52.0–74.0) years; male: 76.3%) were included in the present analysis. HAVB was documented in 3.5% of patients, present on admission in 63.7% of patients and occurring during hospitalisation in 36.3%. Patients with HAVB on admission or occurring during the first 24 h of hospitalisation had higher inhospital mortality rates (18.1% and 28.6%, respectively) than patients without (4.5%) or with HAVB occurring beyond the first 24 h of hospitalisation (8.0%). However by multivariable analysis, HAVB was not independently associated with inhospital mortality contrarily to age, presentation as cardiac arrest, anterior STEMI location, reperfusion therapy, cardiogenic shock, mechanical ventilation and occurrence of sustained ventricular tachyarrhythmias or mechanical complication. <h3>Conclusions</h3> Patients with HAVB had a higher mortality rate than patients without. However HAVB is not an independent predictor of inhospital mortality.

The aim of this study was to test the hypothesis that 6-month dual antiplatelet therapy (DAPT) is noninferior to 24-month DAPT in aspirin-sensitive patients. The ITALIC (Is There a Life for DES After Discontinuation of Clopidogrel) trial showed that rates of bleeding and thrombotic events at 1 year were much the same with 6 versus 12 months of DAPT after percutaneous coronary intervention with second-generation drug-eluting stents. In this report, 2-year follow-up is presented. In a multicenter randomized study, patients with confirmed nonresistance to aspirin undergoing drug-eluting stent implantation were allocated to 6 or 24 months of DAPT. The primary endpoint was a composite of death, myocardial infarction, urgent target vessel revascularization, stroke, and major bleeding at 12 months post–percutaneous coronary intervention. The secondary endpoints comprised the same composite endpoint at 24 months and each individual component. Overall, 2,031 patients from 70 centers were screened; 926 were randomized to 6-month and 924 to 24-month DAPT. Noninferiority was demonstrated for 6- versus 12-month DAPT, with an absolute risk difference of 0.11% (95% confidence interval: −1.04% to 1.26%; p = 0.0002). At 2 years, the composite endpoint was unchanged, at 3.5% for 6 months and 3.7% for 24 months (p = 0.79), and rates of myocardial infarction (1.3% vs. 1.0%; p = 0.51), stroke (0.6% vs. 0.8%; p = 0.77), and target vessel revascularization (1.0% vs. 0.3%; p = 0.09) were likewise similar. There was a trend toward higher mortality with longer DAPT (2.2% vs. 1.2%; p = 0.11). Four patients (0.4%) in the 24-month group and none in the 6-month group had major bleeding. Two-year outcomes in the ITALIC trial confirmed the 1-year results and showed that patients receiving 6-month DAPT after percutaneous coronary intervention with second-generation drug-eluting stent have similar outcomes to those receiving 24-month DAPT.

<b>Objective</b>&nbsp;To compare clinical outcomes between short term (up to 6 months) and long term (12 months) dual antiplatelet therapy (DAPT) after placement of a drug eluting stent in patients with and without diabetes. <b>Design</b>&nbsp;Individual participant data meta-analysis. Cox proportional regression models stratified by trial were used to assess the impact of diabetes on outcomes. <b>Data source</b>&nbsp;Medline, Embase, and Cochrane databases and proceedings of international meetings searched for randomised controlled trials comparing durations of DAPT after placement of a drug eluting stent. Individual patient data pooled from six DAPT trials. <b>Primary outcome</b>&nbsp;Primary study outcome was one year risk of major adverse cardiac events (MACE), defined as cardiac death, myocardial infarction, or definite/probable stent thrombosis. All analyses were conducted by intention to treat. <b>Results</b>&nbsp;Six trials including 11 473 randomised patients were pooled. Of these patients, 3681 (32.1%) had diabetes and 7708 (67.2%) did not (mean age 63.7 (SD 9.9) and 62.8 (SD 10.1), respectively), and in 84 (0.7%) the information was missing. Diabetes was an independent predictor of MACE (hazard ratio 2.30, 95% confidence interval 1.01 to 5.27; P=0.048 At one year follow-up, long term DAPT was not associated with a decreased risk of MACE compared with short term DAPT in patients with (1.05, 0.62 to 1.76; P=0.86) or without (0.97, 0.67 to 1.39; P=0.85) diabetes (P=0.33 for interaction). The risk of myocardial infarction did not differ between the two DAPT regimens (0.95, 0.58 to 1.54; P=0.82; for those with diabetes and 1.15, 0.68 to 1.94; P=0.60; for those without diabetes (P=0.84 for interaction). There was a lower risk of definite/probable stent thrombosis with long term DAPT among patients with (0.26, 0.09 to 0.80; P=0.02) than without (1.42, 0.68 to 2.98; P=0.35) diabetes, with positive interaction testing (P=0.04 for interaction), although the landmark analysis showed a trend towards benefit in both groups. Long term DAPT was associated with higher rates of major or minor bleeding, irrespective of diabetes (P=0.37 for interaction). <b>Conclusions</b>&nbsp;Although the presence of diabetes emerged as an independent predictor of MACE after implantation of a drug eluting stent, compared with short term DAPT, long term DAPT did not reduce the risk of MACE but increased the risk of bleeding among patients with stents with and without diabetes.

Very few women become interventional cardiologists, although a substantial proportion of cardiologists and the majority of medical students are women. In accordance with the EAPCI Women Committee mission of attaining gender equality at the professional level, a worldwide survey was recently conducted aiming to understand better the motivations and the barriers for women in selecting interventional cardiology (IC) as a career path.A total of 1,787 individuals (60.7% women) responded to the survey. Women compared to men were less frequently married (women vs. men, 57.0% vs. 79.8%, p<0.001) and more frequently childless (46.6% vs. 20.5%, p<0.002). The most prevalent reason for choosing IC was passion (83.3% vs. 76.1%, p=0.12), while those for not choosing were, sequentially, lack of opportunity (29.0% vs. 45.7%), radiation concerns (19.9% vs. 11.6%) and preference (16.2% vs. 29.5%), p<0.001. According to 652 men replying to why, in their opinion, women do not choose IC, on-calls and long working hours were the most frequent reasons (35.3%).Several barriers preclude women from choosing IC, including lack of opportunity, concerns regarding radiation exposure and the prejudices of their male colleagues. This highlights the need to develop new strategies for future training, education, and support of women in order to choose IC.

This study sought to evaluate the optimal duration of dual antiplatelet therapy (DAPT) after the implantation of a drug-eluting stent (DES) in elderly patients.Qualified studies to evaluate the optimal duration of DAPT in elderly patients have been very limited.Using 6 randomized trials that compared short-term (≤6 months) and long-term (12 months) DAPT, individual participant data meta-analysis was performed in elderly patients (≥65 years of age). The primary study outcome was the 12-month risk of a composite of myocardial infarction, definite or probable stent thrombosis, or stroke. The major secondary outcome was the 12-month risk of major bleeding.The primary outcome risk did not significantly differ between patients receiving short-term and long-term DAPT (hazard ratio [HR]: 1.12; 95% confidence interval [CI]: 0.88 to 1.43; p = 0.3581) in the overall group of study participants. In subgroup analysis, a significant interaction between age and DAPT duration was observed for primary outcome risk (p for interaction = 0.0384). In the subset of younger patients (<65 years of age, n = 6,152), short-term DAPT was associated with higher risk of primary outcome (HR: 1.67; 95% CI: 1.14 to 2.44; p = 0.0082). In elderly patients (n = 5,319), however, the risk of primary outcome did not significantly differ between patients receiving short-term and long-term DAPT (HR: 0.84; 95% CI: 0.60 to 1.16; p = 0.2856). Short-term DAPT was associated with a significant reduction in major bleeding compared with long-term DAPT (HR: 0.50; 95% CI: 0.30 to 0.84; p = 0.0081) in the overall group, and particularly in elderly patients (HR: 0.46; 95% CI: 0.24-0.88; p = 0.0196).Short-term DAPT after new-generation DES implantation may be more beneficial in elderly patients than in younger patients.

The durability of transcatheter aortic bioprosthetic valves is a crucial issue, but data are scarce, especially beyond 5 years of follow-up. We aimed to assess long-term (7 years) structural valve deterioration (SVD) and bioprosthetic valve failure of transcatheter aortic bioprosthetic valves.Consecutive patients with at least 5-year follow-up available undergoing transcatheter aortic valve implantation from April 2002 to December 2011 in 5 French centers were included. Incidence of SVD and bioprosthetic valve failure were defined according to newly standardized criteria of the European Association of Percutaneous Cardiovascular Interventions/European Society of Cardiology/European Association for Cardio-Thoracic Surgery and reported as cumulative incidence function to account for the competing risk of death. One thousand four hundred three consecutive patients were included with a mean age of 82.6±7.5 years and with a mean logistic EuroSCORE (European System for Cardiac Operative Risk Evaluation) of 21.3±7.5%. A balloon-expandable valve was used in 83.7% of cases. Survival rates were 83.5% (95% CI, 81.4%-85.5%) and 18.6% (95% CI, 15.3%-21.8%) at 1 and 7 years, respectively. Median duration of follow-up was 3.9 years. Bioprosthetic valve failure occurred in 19 patients with a 7-year cumulative incidence of 1.9% (95% CI, 1.4%-2.4%). SVD occurred in 49 patients (moderate, n=32; severe, n=17) with a 7-year cumulative incidence of moderate and severe SVD of 7.0% (95% CI, 5.6%-8.4%) and 4.2% (95% CI, 2.9%-5.5%), respectively. Five patients had aortic valve reintervention (1.0%; 95% CI, 0.4%-1.6%) including 1 case of surgical aortic valve replacement and 4 redo-transcatheter aortic valve implantation. The incidences of SVD and bioprosthetic valve failure were not significantly different between balloon and self-expandable prostheses.The long-term assessment of transcatheter aortic bioprosthetic valves durability is limited by the poor survival of our population beyond 5 years. Further studies are warranted, particularly in younger and lower-risk patients.

Using French transcatheter aortic valve replacement (TAVR) registries linked with the nationwide administrative databases, the study compared the rates of long-term mortality, bleeding, and ischemic events after TAVR in patients requiring oral anticoagulation with direct oral anticoagulants (DOACs) or vitamin K antagonists (VKAs).The choice of optimal drug for anticoagulation after TAVR remains debated.Data from the France-TAVI and FRANCE-2 registries were linked to the French national health single-payer claims database, from 2010 to 2017. Propensity score matching was used to reduce treatment-selection bias. Two primary endpoints were death from any cause (efficacy) and major bleeding (safety).A total of 24,581 patients who underwent TAVR were included and 8,962 (36.4%) were treated with OAC. Among anticoagulated patients, 2,180 (24.3%) were on DOACs. After propensity matching, at 3 years, mortality (hazard ratio [HR]: 1.37; 95% confidence interval [CI]: 1.12-1.67; P < 0.005) and major bleeding including hemorrhagic stroke (HR: 1.64; 95% CI: 1.17-2.29; P < 0.005) were lower in patients on DOACs compared with those on VKAs. The rates of ischemic stroke (HR: 1.32; 95% CI: 0.81-2.15; P = 0.27) and acute coronary syndrome (HR: 1.17; 95% CI: 0.68-1.99; P = 0.57) did not differ among groups.In these large multicenter French TAVR registries with an exhaustive clinical follow-up, the long-term mortality and major bleeding were lower with DOACs than VKAs at discharge. The present study supports preferential use of DOACs rather than VKAs in patients requiring oral anticoagulation therapy after TAVR.

Acute myocardial infarction complicated by cardiogenic shock (AMICS) is a critical syndrome with a high risk of morbidity and mortality. Current management consists of coronary revascularisation, vasoactive drugs, and circulatory and ventilatory support, which are tailored to patients mainly on the basis of clinicians' experience rather than evidence-based recommendations. For many therapeutic interventions in AMICS, randomised clinical trials have not shown a meaningful survival benefit, and a disproportionately high rate of neutral and negative results has been reported. In this context, an accurate definition of the AMICS syndrome for appropriate patient selection and optimisation of study design are warranted to achieve meaningful results and pave the way for new, evidence-based therapeutic options. In this Position Paper, we provide a statement of priorities and recommendations agreed by a multidisciplinary group of experts at the Critical Care Clinical Trialists Workshop in February, 2020, for the optimisation and harmonisation of clinical trials in AMICS. Implementation of proposed criteria to define the AMICS population-moving beyond a cardio-centric definition to that of a systemic disease-and steps to improve the design of clinical trials could lead to improved outcomes for patients with this life-threatening syndrome.

Acute hemodynamic data of left ventricular based pacing were assessed in 2 groups of patients with severe cardiac failure: 11 patients with atrial fibrillation and 17 patients with sinus rhythm. Both biventricular and left ventricular pacing significantly improved acute hemodynamic findings to a similar degree in both groups, suggesting that left ventricular based pacing may be beneficial in patients with severe cardiac failure regardless of whether or not they are in sinus rhythm.

Ruptured coronary atheromatous plaque is generally considered to involve a high risk of subsequent clinical events. Few data are available on the natural evolution of non-culprit-lesion ruptured plaque. We therefore used serial intravascular ultrasound (IVUS) to study how such lesions, detected in the context of a first acute coronary syndrome with elevated troponin I levels, develop.Fourteen patients with 28 distinct plaque ruptures (2+/-1 per patient) without significant associated stenosis (minimal lumen cross-sectional area >4 mm2) were included and systematically treated with 40 mg statin and antiplatelet agent (clopidogrel and aspirin for > or =9 months). Mean clinical and IVUS follow-up was 22+/-13 months (median, 22 months). No clinical event related to the lesion under study occurred. On final IVUS examination, half (14 of 28) of the ruptured plaques had healed, and the degree of stenosis tended to diminish (stenosis, 22+/-17% versus 29+/-17% at baseline; P=0.056). No healing-prediction criterion could be identified.Nearly 2 years of follow-up found that spontaneous coronary atheromatous plaque rupture without significant stenosis detected on first acute coronary syndrome healed without significant plaque modification in 50% of cases with medical therapy.
