Predictors of haemodynamic structural valve deterioration following transcatheter aortic valve implantation with latest-generation balloon-expandable valves

摘要

Aims: Elevated gradients have been proposed to be associated with haemodynamic structural valve deterioration (SVD) after transcatheter aortic valve implantation (TAVI); however, data regarding their characterisation remain scarce. This study sought to investigate the prevalence and predictors of moderate or greater SVD and the prevalence of valve thrombosis during follow-up after TAVI with balloon-expandable valves.
