Aortic Regurgitation Index Ratio Is a Strong Predictor of 1-Year Mortality After Transcatheter Aortic Valve Implantation Using Self-Expanding Devices

Grading paravalvular leak (PVL) at the time of transcatheter aortic valve implantation (TAVI) deployment is challenging. Per-procedural invasive hemodynamic measurements could serve to optimize PVL grading and predict outcome after TAVI. The aim of this study was to compare hemodynamic measures of paravalvular leak and their prognostic relevance in self-expanding TAVI devices. Between December 2008 and December 2017 consecutive patients treated for severe symptomatic aortic valve stenosis with self-expanding devices were prospectively studied.
