A randomized controlled phase III study comparing hadrontherapy with carbon ions versus conventional radiotherapy - including photon and proton therapy - for the treatment of radioresistant tumors: the ETOILE trial.

BACKGROUND: Some cancers such as sarcomas (bone and soft tissue sarcomas) and adenoid cystic carcinomas are considered as radioresistant to low linear energy transfer radiation (including photons and protons) and may therefore beneficiate from a carbon ion therapy. Despite encouraging results obtained in phase I/II trials compared to historical data with photons, the spread of carbon ions has been limited mainly because of the absence of randomized medical data. The French health authorities stressed the importance of having randomized data for carbon ion therapy. METHODS: The ETOILE study is a multicenter prospective randomized phase III trial comparing carbon ion therapy to either advanced photon or proton radiotherapy for inoperable or macroscopically incompletely resected (R2) radioresistant cancers including sarcomas and adenoid cystic carcinomas. In the experimental arm, carbon ion therapy will be performed at the National Center for Oncological Hadrontherapy (CNAO) in Pavia, Italy. In the control arm, photon or proton radiotherapy will be carried out in referent centers in France. The primary endpoint is progression-free survival (PFS). Secondary endpoints are overall survival and local control, toxicity profile, and quality of life. In addition, a prospective health-economic study and a radiobiological analysis will be conducted. To demonstrate an absolute improvement in the 5-year PFS rate of 20% in favor of carbon ion therapy, 250 patients have to be included in the study. DISCUSSION: So far, no clinical study of phase III has demonstrated the superiority of carbon ion therapy compared to conventional radiotherapy, including proton therapy, for the treatment of radioresistant tumors.

Five-Year Clinical Outcome and Valve Durability After Transcatheter Aortic Valve Replacement in High-Risk Patients.

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 <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 <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.

Postprocedural aortic regurgitation in balloon-expandable and self-expandable transcatheter aortic valve replacement procedures: analysis of predictors and impact on long-term mortality: insights from the FRANCE2 Registry.

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

Registry of transcatheter aortic-valve implantation in high-risk patients.

BACKGROUND: 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. METHODS: 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. RESULTS: 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. CONCLUSIONS: 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.

Impact of pre- and post-procedural anemia on the incidence of acute kidney injury and 1-year mortality in patients undergoing transcatheter aortic valve implantation (from the French Aortic National CoreValve and Edwards 2 [FRANCE 2] Registry).

OBJECTIVES: The relationship between anemia, renal insufficiency, and the outcomes of TAVI patients has not been thoroughly studied. We aimed to evaluate the influence of pre- and post-procedural anemia on the incidence of renal insufficiency, especially AKI, and on the outcomes of TAVI. METHODS: Data from the French national TAVI registry were collected in 3,472 patients who underwent TAVI between January 2010 and December 2012. Of these 2,137 were in the no/mild anemia group, 748 were in the moderate anemia group, and 587 were in the severe anemia group before TAVI. Furthermore, we divided the 3,472 patients into three groups according to post-procedural anemia, measured as post-procedural hemoglobin (Hb) drop: <2 g/dl (n=1,633, group 1), 2 to <4 g/dl (n=1,458, group 2), and >4 g/dl (n = 381, group 3). Procedure and outcome variables were compared. RESULTS: Increased severity of anemia before TAVI was associated with significantly different rates of 1-year mortality (15%, 19%, and 24%, P<0.01), with similar differences in the incidence of AKI (5%, 8%, and 10%, P<0.01). Increased severity of Hb drop was associated with significantly different rates of 1-year mortality (16%, 18%, and 23%, P<0.01), and with similar differences in the incidence of AKI (6%, 7%, and 10%, P=0.04). Both pre- and post-procedural anemia were predictors of the incidence of AKI (OR 1.82, P<0.01; OR 1.82, P<0.01, respectively) and 1-year mortality (HR 1.44, P<0.01; HR 1.50, P<0.01, respectively). CONCLUSIONS: Both pre- and post-procedural anemia were significantly associated AKI and 1-year mortality.

Long-term follow-up study of endarterectomy versus angioplasty in patients with symptomatic severe carotid stenosis trial.

BACKGROUND AND PURPOSE: We aimed at comparing the long-term benefit-risk balance of carotid stenting versus endarterectomy for symptomatic carotid stenosis. METHODS: Long-term follow-up study of patients included in Endarterectomy Versus Angioplasty in Patients With Symptomatic Severe Carotid Stenosis (EVA-3S), a randomized, controlled trial of carotid stenting versus endarterectomy in 527 patients with recently symptomatic severe carotid stenosis, conducted in 30 centers in France. The main end point was a composite of any ipsilateral stroke after randomization or any procedural stroke or death. RESULTS: During a median follow-up of 7.1 years (interquartile range, 5.1-8.8 years; maximum 12.4 years), the primary end point occurred in 30 patients in the stenting group compared with 18 patients in the endarterectomy group. Cumulative probabilities of this outcome were 11.0% (95% confidence interval, 7.9-15.2) versus 6.3% (4.0-9.8) in the endarterectomy group at the 5-year follow-up (hazard ratio, 1.85; 1.00-3.40; P=0.04) and 11.5% (8.2-15.9) versus 7.6% (4.9-11.8; hazard ratio, 1.70; 0.95-3.06; P=0.07) at the 10-year follow-up. No difference was observed between treatment groups in the rates of ipsilateral stroke beyond the procedural period, severe carotid restenosis (≥70%) or occlusion, death, myocardial infarction, and revascularization procedures. CONCLUSIONS: The long-term benefit-risk balance of carotid stenting versus endarterectomy for symptomatic carotid stenosis favored endarterectomy, a difference driven by a lower risk of procedural stroke after endarterectomy. Both techniques were associated with low and similar long-term risks of recurrent ipsilateral stroke beyond the procedural period. CLINICAL TRIAL REGISTRATION URL: http://www.clinicaltrials.gov.

How can the quality of medical data in pharmacovigilance, pharmacoepidemiology and clinical studies be guaranteed?

The development of medicinal products is subject to quality standards aimed at guaranteeing that database contents accurately reflect the source documents. Paradoxically, these standards hardly address the quality of the source data itself. The objective of this work was to propose recommendations to improve data quality in three fields (pharmacovigilance, pharmacoepidemiology and clinical studies). The analysis was focused on the data and on the critical stages presenting critical quality problems, for which the current guidelines are insufficiently detailed, unsuitable and/or poorly applied. Finally, recommendations have been proposed, mainly focused on the origin of the data and its transcription.

Contemporary model for cardiovascular risk prediction in people with type 2 diabetes.

BACKGROUND: Existing cardiovascular risk prediction equations perform non-optimally in different populations with diabetes. Thus, there is a continuing need to develop new equations that will reliably estimate cardiovascular disease (CVD) risk and offer flexibility for adaptation in various settings. This report presents a contemporary model for predicting cardiovascular risk in people with type 2 diabetes mellitus. DESIGN AND METHODS: A 4.5-year follow-up of the Action in Diabetes and Vascular disease: preterax and diamicron-MR controlled evaluation (ADVANCE) cohort was used to estimate coefficients for significant predictors of CVD using Cox models. Similar Cox models were used to fit the 4-year risk of CVD in 7168 participants without previous CVD. The model's applicability was tested on the same sample and another dataset. RESULTS: A total of 473 major cardiovascular events were recorded during follow-up. Age at diagnosis, known duration of diabetes, sex, pulse pressure, treated hypertension, atrial fibrillation, retinopathy, HbA1c, urinary albumin/creatinine ratio and non-HDL cholesterol at baseline were significant predictors of cardiovascular events. The model developed using these predictors displayed an acceptable discrimination (c-statistic: 0.70) and good calibration during internal validation. The external applicability of the model was tested on an independent cohort of individuals with type 2 diabetes, where similar discrimination was demonstrated (c-statistic: 0.69). CONCLUSIONS: Major cardiovascular events in contemporary populations with type 2 diabetes can be predicted on the basis of routinely measured clinical and biological variables. The model presented here can be used to quantify risk and guide the intensity of treatment in people with diabetes.

Patient characteristics and treatment of neovascular age-related macular degeneration in France: the LUEUR1 observational study.

BACKGROUND: Age-related macular degeneration is the primary cause of blindness in developed countries. Current treatments of this degenerative disease mainly include laser, photodynamic therapy with verteporfin and administration of anti-vascular endothelial growth factors. The LUEUR (LUcentis® En Utilisation Réelle) study is composed of a cross-sectional part (LUEUR1), which examined the current management of wet AMD in France, and a follow-up part (LUEUR2), which will assess the development of patients treated for wet AMD over 4 years. Here we describe the results of LUEUR1. METHODS: Patients with wet AMD were enrolled during a routine medical examination in LUEUR1, a cross-sectional, observational, prospective, multicentre study. Investigators recorded patient demographics, visual acuity, characteristics of wet AMD lesions, date of AMD diagnosis, comorbidities, previous treatments, treatments prescribed at inclusion, and low vision rehabilitation. RESULTS: A total of 72 investigators recruited 1,019 patients with wet AMD, corresponding to 1,405 eyes affected by the disease. The mean age of patients was 78.7 ± 7.3 years. Most were female (62.3%) and non-smokers (66.9%). The mean visual acuity was 49.12 ± 24.18 Early Treatment Diabetic Retinopathy Study letters. Most eyes showed occult (52.8%) and subfoveal (84.6%) choroidal neovascularisation. Bilateral wet AMD affected 37.9% of patients. The median time since diagnosis was 12 months. Ranibizumab-based therapy (67.3%) and photodynamic therapy (29.8%) were the most frequent previous treatments. Prior to inclusion, 5.6% of patients had low vision rehabilitation. When a treatment was prescribed on the day of inclusion, it was most often ranibizumab (89.0% of all treatments at inclusion). CONCLUSIONS: The results of this study illustrate the impact of anti-vascular endothelial growth factor therapies on the treatment of wet AMD in a real-life context. Specifically, ranibizumab-based therapy appears to have largely replaced laser photocoagulation and verteporfin-based photodynamic therapy.

High Post-Procedural Transvalvular Gradient or Delayed Mean Gradient Increase after Transcatheter Aortic Valve Implantation: Incidence, Prognosis and Associated Variables. The FRANCE-2 Registry.

Mean Gradient (MG) elevation can be detected immediately after transcatheter aortic valve implantation (TAVI) or secondarily during follow-up. Comparisons and interactions between these two parameters and their impact on outcomes have not previously been investigated. This study aimed to identify incidence, influence on prognosis, and parameters associated with immediate high post-procedural mean transvalvular gradient (PPMG) and delayed mean gradient increase (6 to 12 months after TAVI, DMGI) in the FRANCE 2 (French Aortic National CoreValve and Edwards 2) registry. The registry includes all consecutive symptomatic patients with severe aortic stenosis who have undergone TAVI. Three groups were analyzed: (1) PPMG < 20 mmHg without DMGI > 10 mmHg (control); (2) PPMG < 20 mmHg with DMGI > 10 mmHg (Group 1); and (3) PPMG ≥ 20 mmHg (Group 2). From January 2010 to January 2012, 4201 consecutive patients were prospectively enrolled in the registry. Controls comprised 2078 patients. In Group 1(n = 131 patients), DMGI exceeded 10 mmHg in 5.6%, and was not associated with greater 4-years mortality than in controls (32.6% vs. 40.1%, p = 0.27). In Group 2 (n = 144 patients), PPMG was at least 20 mmHg in 6.1% and was associated with higher 4-year mortality (48.7% versus 40.1%, p = 0.005). A total of two-thirds of the patients with PPMG ≥ 20 mmHg had MG < 20 mmHg at 1 year, with mortality similar to the controls (39.2% vs. 40.1%, p = 0.73). Patients with PPMG > 20 mmHg 1 year post-TAVI had higher 4-years mortality than the general population of the registry, unlike patients with MG normalization.

Candesartan improves blood pressure control and reduces proteinuria in renal transplant recipients: results from SECRET.

BACKGROUND: Hypertension is a risk factor for the two leading causes of death in renal transplant recipients: cardiovascular disease (CVD) and graft failure. Despite this, the optimum medication for post-transplant hypertension is unclear. METHODS: The Study on Evaluation of Candesartan Cilexetil after Renal Transplantation (SECRET) was an international multicentre, double-blind, randomized investigation of the angiotensin II type 1 receptor blocker (ARB) candesartan cilexetil versus placebo in renal allograft recipients originally designed to study 700 patients for 3 years. The candesartan dose was escalated from 4 to 16 mg daily, followed by addition of co-medication, if needed, with the aim of achieving a diastolic blood pressure (BP) <85 mmHg. The primary efficacy variable was a composite of all-cause mortality, cardiovascular morbidity and graft failure. RESULTS: SECRET was stopped prematurely as the primary event rate was much lower than expected. At that point, 502 patients were enrolled; 255 received candesartan and 247 placebo. Thirteen primary events had occurred in each group. Control of both systolic and diastolic BP was better in the candesartan group. Urinary protein excretion and protein/creatinine ratio decreased on candesartan but increased on placebo. Serum creatinine and potassium were increased in candesartan patients, but these changes were generally small. CONCLUSIONS: SECRET provides insights into the design and conduct of studies in this area and evidence for the utility of candesartan, which showed good safety and tolerability, improved BP control and decreased proteinuria in renal transplant recipients.

Endarterectomy versus stenting in patients with symptomatic severe carotid stenosis.

BACKGROUND: Carotid stenting is less invasive than endarterectomy, but it is unclear whether it is as safe in patients with symptomatic carotid-artery stenosis. METHODS: We conducted a multicenter, randomized, noninferiority trial to compare stenting with endarterectomy in patients with a symptomatic carotid stenosis of at least 60%. The primary end point was the incidence of any stroke or death within 30 days after treatment. RESULTS: The trial was stopped prematurely after the inclusion of 527 patients for reasons of both safety and futility. The 30-day incidence of any stroke or death was 3.9% after endarterectomy (95% confidence interval [CI], 2.0 to 7.2) and 9.6% after stenting (95% CI, 6.4 to 14.0); the relative risk of any stroke or death after stenting as compared with endarterectomy was 2.5 (95% CI, 1.2 to 5.1). The 30-day incidence of disabling stroke or death was 1.5% after endarterectomy (95% CI, 0.5 to 4.2) and 3.4% after stenting (95% CI, 1.7 to 6.7); the relative risk was 2.2 (95% CI, 0.7 to 7.2). At 6 months, the incidence of any stroke or death was 6.1% after endarterectomy and 11.7% after stenting (P=0.02). There were more major local complications after stenting and more systemic complications (mainly pulmonary) after endarterectomy, but the differences were not significant. Cranial-nerve injury was more common after endarterectomy than after stenting. CONCLUSIONS: In this study of patients with symptomatic carotid stenosis of 60% or more, the rates of death and stroke at 1 and 6 months were lower with endarterectomy than with stenting.

New insights on the relation between untreated and treated outcomes for a given therapy effect model is not necessarily linear.

BACKGROUND AND OBJECTIVES: A relation between the size of treatment efficacy and severity of the disease has been postulated and observed as linear for a few therapies. We have called this relation the effect model. Our objectives were to demonstrate that the relation is general and not necessarily linear. STUDY DESIGN AND SETTING: We extend the number of observed effect model. Then we established three numerical models of treatment activity corresponding to the three modes of action we have identified. Using these models, we simulated the relation. RESULTS: Empirical evidence confirms the effect model and suggests that it may be linear over a short range of event frequency. However, it provides an incomplete understanding of the phenomenon because of the inescapable limitations of data from randomized clinical trials. Numerical modeling and simulation show that the real effect model is likely to be more complicated. It is probably linear only in rare instances. The effect model is general. It depends on factors related to the individual, disease and outcome. CONCLUSION: Contrarily to common, assumption, since the effect model is often curvilinear, the relative risk cannot be granted as constant. The effect model should be taken into account when discovering and developing new therapies, when making, health care policy decisions or adjusting clinical decisions to the patient risk profile.

Assessment of patients' and physicians' compliance to an ACE inhibitor treatment based on urinary N-acetyl Ser-Asp-Lys-Pro determination in the Noninsulin-Dependent Diabetes, Hypertension, Microalbuminuria, Proteinuria, Cardiovascular Events, and Ramipril (DIABHYCAR) study.

OBJECTIVE: The purpose of this study was to assess patients' and physicians' compliance with ACE inhibitor treatment, by measuring an endogenous biomarker of ACE inhibition, urinary N-acetyl-Ser-Asp-Lys-Pro (AcSDKP), in the Noninsulin-Dependent Diabetes, Hypertension, Microalbuminuria, Proteinuria, Cardiovascular Events, and Ramipril (DIABHYCAR) trial, which compared ramipril (1.25 mg o.d.) with placebo in 4,912 patients with type 2 diabetes and microalbuminuria/proteinuria. RESEARCH DESIGN AND METHODS: The urine AcSDKP-to-creatinine ratio was measured blind to treatment in all participants who completed follow-up and provided spot urine samples (n = 1,871). RESULTS: The median urinary AcSDKP-to-creatinine ratio was six times higher for ramipril than for placebo. Urinary AcSDKP-to-creatinine ratios displayed a bimodal distribution in both groups, with a very large intergroup overlap. Based on cluster analysis, we defined truly adherent ramipril patients as those with a ratio > or =4 nmol/mmol and truly adherent placebo patients as those with a ratio < 4 nmol/mmol. After excluding patients withdrawing prematurely from the study or known to have used a nonstudy ACE inhibitor, 27.3% of the 597 ramipril patients had ratios <4, indicating poor compliance, and 9.7% of the 621 placebo patients had ratios > or =4, indicating intake of a nonstudy ACE inhibitor. Correcting for compliance by using AcSDKP-guided analysis affected surrogate outcome results (decrease in systolic blood pressure and urinary albumin excretion) only slightly. CONCLUSIONS: The systematic use of spot urinary AcSDKP determination facilitated the detection of defects in compliance with ACE inhibitor treatment in both patients and physicians. Urinary AcSDKP measurement could be a useful biomarker for assessing compliance with ACE inhibition in the routine care of diabetic patients.

Baseline characteristics and outcomes after transcatheter aortic-valve implantation in patients with or without previous balloon aortic valvuloplasty: Insights from the FRANCE 2 registry.

BACKGROUND: Some patients who are at high surgical risk because of multiple co-morbidities undergo balloon aortic valvuloplasty (BAV) as a bridge therapy towards transcatheter aortic-valve implantation (TAVI). AIM: The aim of this study was to compare the clinical course of patients with or without previous BAV who underwent TAVI and were included in the FRANCE 2 registry. METHODS: From January 2010 to December 2011, 3953 patients underwent TAVI. Survival analysis was done by multivariable regression and propensity-score analysis to adjust for confounders. RESULTS: Patients in the previous BAV group (n=664, 16.8%) were older than patients in the primary TAVI group. The logistic EuroSCORE I and the rates of co-morbidities and symptoms were higher in the previous BAV group. Procedural success was similar in both groups, as was postprocedural aortic regurgitation grade≥2/4. The 1-month mortality rates from all causes were 12.5 and 8.7%, respectively, in the previous BAV and primary TAVI groups (P=0.001). The 1-month to 1-year mortality rates were similar in both groups. Previous BAV was not an independent predictor of 1-month mortality (hazard ratio 1.44, 95% confidence interval 0.90-2.34; P=0.14) or 1-month to 1-year mortality. CONCLUSIONS: Crude 1-month mortality was higher in patients with previous BAV. Nevertheless, precarious preoperative status, but not previous BAV, was associated with mortality, and is the only marker that should be considered as detrimental at the time of preTAVI reassessment.

Impact of coronary artery disease in patients undergoing transcatheter aortic valve replacement: Insights from the FRANCE-2 registry.

BACKGROUND: Coronary artery disease (CAD) is common in patients undergoing transcatheter aortic valve replacement (TAVR). However, the impact of CAD distribution before TAVR on short- and long-term prognosis remains unclear. HYPOTHESIS: We hypothesized that the long-term clinical impact differs according to CAD distribution in patients undergoing TAVR using the FRench Aortic National CoreValve and Edwards (FRANCE-2) registry. METHODS: FRANCE-2 is a national French registry including all consecutive TAVR performed between 2010 and 2012 in 34 centers. Three-year mortality was assessed in relation to CAD status. CAD was defined as at least 1 coronary stenosis >50%. RESULTS: A total of 4201 patients were enrolled in the registry. For the present analysis, we excluded patients with a history of coronary artery bypass. CAD was reported in 1252 patients (30%). Half of the patients presented with coronary multivessel disease. CAD extent was associated with an increase in cardiovascular risk profile and in logistic EuroSCORE (European System for Cardiac Operative Risk Evaluation) (from 19.3% ± 12.8% to 21.9% ± 13.5%, P < 0.001). Mortality at 30 days and 3 years was 9% and 44%, respectively, in the overall population. In multivariate analyses, neither the presence nor the extent of CAD was associated with mortality at 3 years (presence of CAD, hazard ratio [HR]: 0.90; 95% confidence interval [CI]: 0.78-1.07). A significant lesion of the left anterior descending (LAD) was associated with higher 3-year mortality (HR: 1.42; 95% CI: 1.10-1.87). CONCLUSIONS: CAD is not associated with decreased short- and long-term survival in patients undergoing TAVR. The potential deleterious effect of LAD disease on long-term survival and the need for revascularization before or at the time of TAVR should be validated in a randomized control trial.
