Predictors of in-hospital early mortality following valve-in-valve transcatheter aortic valve replacement.

Background: There is an increasing preference of utilizing valve-in-valve transcatheter aortic valve replacement (ViV TAVR) after bioprosthetic valve failure. However, updated large-scale analysis investigating early-mortality after the patients underwent ViV TAVR is limited.

Objective: This study aimed to assess in-hospital early mortality and analyze the factors associated with in-hospital early mortality among patients who underwent ViV TAVR.
