Zusammenfassung
Objectives: Aim of study was to assess the influence of the amount of calcifications of the aortic valve and the left ventricular outflow tract (LVOT) on the acute procedural outcome in patients undergoing transcatheter aortic valve implantation (TAVI). Aims: TAVI is an established procedure for high-risk patients with significant aortic stenosis (AS, 1–3). After TAVI post-interventional paravalvular aortic regurgitation (PAR) can occur, which is believed to be related to calcifications in the device ‘landing zone’ (DLZ, 4). Recently developed aortic valve calcification scores don´t consider the LVOT as part of…
