Procedural Volume and Outcomes for Transcatheter Aortic-Valve Replacement

Abstract

An inverse volume-mortality association was observed for transfemoral TAVR procedures from 2015 through 2017. Mortality at 30 days was higher and more variable at hospitals with a low procedural volume than at hospitals with a high procedural volume.
