Intentional Computed Tomography-based Oversizing in Balloon-expandable Transcatheter Aortic Valve Implantation – Incidence of Paravalvular Regurgitation and Post-deployment Geomet…

Ziele: To evaluate the outcome in regard to paravalvular regurgitation and post-deployment geometry of intentional computed tomography (CT)-based oversizing of Transcatheter Heart Valves (THV) in Transcatheter Aortic Valve Implantation (TAVI) using pre- and post-deployment dual-source CT. Methode: Seventy-nine patients with severe aortic stenosis (mean age 81 ± 8 years, mean aortic valve area 0.69 ± 0.18 cm2) underwent retrospectively gated DSCT for THV sizing prior to TAVI. Aortic annulus dimensions were quantified by means of planimetry and area-derived diameter calculation (calculated average annulus diameter…
