BACKGROUND 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. METHODS AND RESULTS The FRANCE 2 Registry included all patients undergoing transcatheter aortic valve implantation in France in(More)
Aneurysms of saphenous vein grafts to coronary arteries are unusual complications of coronary artery bypass graft (CABG) surgery. Three patients (men aged 47, 62, and 68 years) are presented with spontaneous chest pains 10, 21, and 17 years after CABG surgery. In one case, the saphenous vein graft had eroded into the right atrium and had established a(More)
BACKGROUND Gender differences in presentation, management and outcome in patients with ST-segment elevation myocardial infarction (STEMI) have been reported. AIM To determine whether female gender is associated with higher inhospital mortality. METHODS Data from ORBI, a regional STEMI registry of 5 years' standing, were analysed. The main data on(More)
This study was undertaken to determine the feasibility and safety of coronary stenting in acute myocardial infarction (AMI). In AMI, primary percutaneous transluminal coronary angioplasty (PTCA) is accepted as the preferred method of reperfusion for patients presenting at highly experienced centres. Until recently, however, stenting has been avoided during(More)
BACKGROUND The SWIBAP (stent without balloon predilatation) prospective randomised trial was designed to compare direct coronary stenting with stenting preceded by lesion predilatation with an angioplasty balloon. OBJECTIVE To determine the feasibility and safety of direct stenting in non-complex coronary lesions in a prospective study. PATIENTS AND(More)
BACKGROUND Patient selection for transcatheter aortic valve implantation (TAVI) remains a major concern. Indeed, despite promising results, it is still unclear which patients are most and least likely to benefit from this procedure. AIMS To identify predictors of 6-month poor clinical outcomes after TAVI. METHODS Patients who were discharged from our(More)
Previous studies investigating prehospital use of glycoprotein IIb/IIIa inhibitors (GPIs) in patients with ST-segment elevation myocardial infarction reached conflicting conclusions. The benefit of this strategy in addition to in-ambulance loading of dual-antiplatelet therapy remains controversial. The aim of this study was to analyze data from a(More)
AIMS Myocardial infarction with unobstructed coronary artery disease represents a serious diagnostic challenge. The role of cardiac magnetic resonance in the management of cardiomyopathies is increasing. We examined the diagnostic contributions of cardiac magnetic resonance in patients presenting with acute chest pain syndrome, elevated serum cardiac(More)
Pathogenesis of peripartum cardiomyopathy (PPC) is still discussed. We report one case of PPC in which a cardiac magnetic resonance imaging analysis allowed to exclude some "classical" pathogenesis hypotheses. We would like to emphasize the benefits of cardiac MRI in the comprehension of the mechanism(s) involved in the genesis of PPC.
BACKGROUND Meta-analyses have confirmed the high performance of multislice computed tomography (MSCT) in coronary stenosis detection. Recent reports have described the study of left ventricular anatomy and function and coronary venous anatomy with MSCT. AIMS We sought to compare, in patients with cardiomyopathy of unknown origin, the performance of MSCT(More)
