The effects of VARC-defined acute kidney injury after transcatheter aortic valve implantation (TAVI) using the Edwards bioprosthesis

Abstract

More than one third of patients sustain AKI after TAVI using the Edwards bioprosthesis, as defined by the VARC-modified RIFLE score. AKI increased the mortality at both 30 days and at one year. A history of diabetes mellitus, peripheral vascular disease and higher chronic kidney disease stage had the strongest independent associations with post-TAVI AKI.
