PURPOSE To assess current antithrombotic treatment strategies in the Netherlands in patients undergoing transcatheter aortic valve implantation (TAVI). METHODS For every Dutch hospital performing TAVI (n = 14) an interventional cardiologist experienced in performing TAVI was interviewed concerning heparin, aspirin, thienopyridine and oral anticoagulation treatment in patients undergoing TAVI....
The introduction of transcatheter aortic valve implantation (TAVI) has resulted in a paradigm shift in the treatment of patients with severe aortic stenosis. Data from the recent U.S CoreValve Trial suggest, for the first time, that TAVI is associated with a significantly higher rate of survival at one year compared to surgical aortic valve replacement (SAVR) in the treatment of high-risk patie...
Transcatheter aortic valves implantation (TAVI) is a valid treatment for high-risk surgical candidates with symptomatic severe aortic stenosis; the safety and effectiveness of TAVI have been demonstrated in numerous clinical studies, national registries and randomized trials. Nevertheless, from this cohort of patients have been often excluded patients with prior mitral valve surgery because con...
The prevalence of coronary artery disease (CAD) ranges from 25% to 50% of all patients with aortic valve stenosis (AVS). Observational studies reporting outcomes of patients undergoing transcatheter aortic valve implantation (TAVI) revealed a prevalence of CAD in the range of 40% to 75%. Current guidelines state that myocardial revascularization at the time of surgical aortic valve repair is a ...
BACKGROUND The clinical significance of left ventricular (LV) diastolic function (DF) improvement after transcatheter aortic valve implantation (TAVI) is not fully elucidated. We sought to investigate the long-term clinical and hemodynamic effects of post-TAVI DF improvement and to identify its determinants.Methods and Results:Clinical and serial echocardiographic data before and after TAVI wer...
BACKGROUND Transaortic transcatheter aortic valve implantation (TAo-TAVI) is a recently developed approach that provides an alternative delivery route for valve replacement in patients with vascular abnormalities or existing comorbidities. While initial studies have shown the principal efficacy and safety, the real world effectiveness and safety of this approach remains to be fully assessed. ...
INTRODUCTION Transcatheter aortic valve implantation (TAVI) is an alternative to surgical aortic valve replacement in patients with severe aortic stenosis (AS) and unacceptably high surgical risk. METHODS We present our first two years' experience with TAVI. A total of 76 AS patients were evaluated for TAVI and 23 of them underwent a TAVI procedure. These patients had a mean EuroSCORE of 22.4...
Many patients have ilio-femoral vessel anatomy unsuitable for conventional trans-femoral (TF) trans-catheter aortic valve implantation (TAVI). Safe and practical alternatives to the TF approach are therefore needed. This study compared outcomes of alternative non-femoral routes, trans-apical (TA), direct aortic (DA) and subclavian (SC), with standard femoral access. In this retrospective study,...
Transcatheter aortic valve implantation (TAVI) can treat symptomatic patients with calcific aortic stenosis. However, the severity and distribution of the calcification of valve leaflets can impair the TAVI efficacy. Here we tackle this issue from a biomechanical standpoint, by finite element simulation of a widely adopted balloon-expandable TAVI in three models representing the aortic root wit...
Introduction: Transcatheter aortic valve implantation (TAVI) is more reliable than surgical valve replacement for high-risk or inoperable aortic stenosis patients. In this study, we aimed to investigate the effects of different femoral access methods on the development of vascular complications and contrast-induced nephropathy (CIN) after transfemoral (TF)-TAVI. Patients and Methods: In total, ...
