AIMS New-onset left bundle branch block (LBBB) and complete atrioventricular block (AV3B) frequently occur following transcatheter aortic valve implantation (TAVI). We sought to determine the timing and potential mechanisms of new conduction abnormalities (CAs) during TAVI, using the Medtronic CoreValve System (MCS). METHODS AND RESULTS Sixty-five(More)
OBJECTIVES Using multislice computed tomography (MSCT), we sought to evaluate the geometry and apposition of the CoreValve ReValving System (CRS, Medtronic, Luxembourgh, Luxembourgh) in patients with aortic stenosis. BACKGROUND There are no data on the durability of percutaneous aortic valve replacement. Geometric factors may affect durability. METHODS(More)
AIMS Transcatheter aortic valve implantation (TAVI) requires large bore catheters. Access site complications, therefore, can be a concern. The aim of this study is to present the 30-day incidence of major and minor vascular complications in patients treated with the third generation 18 Fr Medtronic CoreValve System. METHODS AND RESULTS We prospectively(More)
The books and articles devoted to the anatomy of the aortic valvar complex are numerous. Until now, however, little consideration has been given to understanding the anatomy with percutaneous valvar replacement in mind. It is axiomatic that knowledge of the anatomy of the valve is fundamental in understanding key principles involved in valvar(More)
AIMS We evaluated the feasibility and the acute performance of the everolimus-eluting bioresorbable vascular scaffolds (BVS) for the treatment of patients presenting with ST-segment elevation myocardial infarction (STEMI). METHODS AND RESULTS The present investigation is a prospective, single-arm, single-centre study, reporting data after the BVS(More)
BACKGROUND To investigate the causes of paravalvular aortic regurgitation (PAR) after the implantation of the Medtronic CoreValve prosthesis (MCRS). METHODS AND RESULTS Fifty-six patients underwent MSCT before TAVI with a MCRS and PAR was assessed with transthoracic echocardiography (TTE) between 5 and 10 days after TAVI. The aortic annulus smallest and(More)
2D/3D registration of patient vasculature from preinterventional computed tomography angiography (CTA) to interventional X-ray angiography is of interest to improve guidance in percutaneous coronary interventions. In this paper we present a novel feature based 2D/3D registration framework, that is based on probabilistic point correspondences, and show its(More)
AIMS Aortic regurgitation (AR) after Medtronic CoreValve System (MCS) implantation may be explained by patient-, operator- and procedure-related factors. We sought to explore if frame geometry, as a result of a specific device-host interaction, contributes to AR. METHODS AND RESULTS Using rotational angiography with dedicated motion compensation, we(More)
