Abstract

OBJECTIVES: Mortality prediction models (MPMs) play a crucial role in risk assessment for transcatheter aortic valve replacement (TAVR), but their external validity in Japanese patients remains unclear. This study evaluated the performance of existing short- (30-day) and long- (one-year) term MPMs with Japanese TAVR patients.
