title: Predicting paravalvular leak after balloon-expandable TAVR.
abstract: Objective measurement of a Valve Calcification Index (calcium volume/BSA) may predict PVL after TAVR using a cutoff value > 418 mm(3) /mm(2) Oversizing the balloon-expandable SAPIEN valve with a goal ratio of valve diameter: average annulus diameter > 1.055 may reduce PVL after TAVR Single parameters are unlikely to provide adequate sensitivity to reduce PVL; a thorough analysis of root sizing, calcification, and morphology is important to balloon-expandable TAVR safety and efficacy.
