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(More)
AIMS To analyse the risk of death according to the type of cerebrovascular complications (CVC) during infective endocarditis (IE) and to analyse the determinants of outcome in patients with IE and a CVC. METHODS AND RESULTS In two referral centres, 496 consecutive patients with definite IE were prospectively included. Cerebral CT scan was performed in 453(More)
BACKGROUND In June 2000 a new ERA-EDTA Registry Office was opened in Amsterdam. This Registry will only collect core data on renal replacement therapy (RRT) through national and regional registries. This paper reports the technical and epidemiological results of a pilot study combining the data from six registries. METHODS Data from the national renal(More)
Patients with severe acute respiratory distress syndrome (ARDS) are candidates for extracorporeal membrane oxygenation (ECMO) therapy. The evaluation of organ severity is difficult in patients considered for cannulation in a distant hospital. This study was designed to identify early factors associated with hospital mortality in ARDS patients treated with(More)
CONTEXT Cardiovascular mortality is considered the main cause of death in patients receiving dialysis and is 10 to 20 times higher in such patients than in the general population. OBJECTIVE To evaluate if high overall mortality in patients starting dialysis is a consequence of increased cardiovascular mortality risk only or whether noncardiovascular(More)
OBJECTIVES In the last decade, cardiac surgery in octogenarians is becoming a routinely performed procedure in our Western countries. The functional benefit of this surgery had already been proved. The aim of this study was to evaluate operative mortality, to identify pre- and post-operative risk factors of early and late mortality, to assess the Euroscore(More)
BACKGROUND The incidence of embolic events (EE) and death is still high in patients with infective endocarditis (IE), and data about predictors of these 2 major complications are conflicting. Moreover, the exact role of echocardiography in risk stratification is not well defined. METHODS AND RESULTS In a multicenter prospective European study, including(More)
BACKGROUND. Blood culture-negative endocarditis (BCNE) may account for up to 31% of all cases of endocarditis. METHODS. We used a prospective, multimodal strategy incorporating serological, molecular, and histopathological assays to investigate specimens from 819 patients suspected of having BCNE. RESULTS. Diagnosis of endocarditis was first ruled out for(More)
To compare characteristics, clinical evolution and outcome in adult patients with influenza A (H1N1) acute respiratory distress syndrome (ARDS) treated with or without extracorporeal membrane oxygenation (ECMO). A prospective observational study of patients treated in Marseille South Hospital from October 2009 to January 2010 for confirmed influenza A(More)
OBJECTIVES This study sought to determine the value of (18)F-fluorodeoxyglucose positron emission tomography/computed tomography ((18)F-FDG PET/CT) for diagnosing prosthetic valve endocarditis (PVE). BACKGROUND The diagnosis of PVE remains challenging. In PVE cases, initial echocardiography is normal or inconclusive in almost 30%, leading to a decreased(More)
