Efficacy and safety of transcatheter aortic valve implantation in patients with severe bicuspid aortic stenosis.

ABSTRACT:

Background

Bicuspid aortic valve (BAV) is common congenital malformation, bicuspid aortic stenosis accounts for a substantial proportion of patients with aortic valve stenosis (AS). Bicuspid AS are more likely to have aortic dilatation with slightly less elliptical annuli, which might lead to paravalvular aortic valve regurgitation (AR) and permanent pacemaker implantation (PPM) after TAVI with higher mortality. Our study aims to understand the therapeutic efficacy and safety of transcatheter aortic valve implantation (TAVI) with a supra-annular structure-based sizing strategy in Chinese AS patients with BAV versus tricuspid aortic valve (TAV).

Methods

Seventy-four consecutive tricuspid AS patients and 44 bicuspid AS patients were included and enrolled in the study for analy
