Predictors of bioprosthetic valve dysfunction after transcatheter aortic valve implantation.

ABSTRACT:

Background

Recently, the Valve Academic Research Consortium (VARC)-3 criteria redefined bioprosthetic valve dysfunction (BVD) after transcatheter aortic valve implantation (TAVI). However, the rate of BVD is scarcely reported in current practice.

Aims

We aimed to evaluate the rate and predictors of BVD after TAVI based on the VARC-3 criteria.

Methods

We retrospectively analysed patients who had undergone TAVI using single-centre data. BVD was reported as exposure-adjusted event rates with a patient-year unit (per 100 patient-years). Predictors of BVD after TAVI were analysed using Fine-Gray competing risk regression to account for the competing risk of death.

Results

Among 514 patients, the rate of BVD was 7.5 events per 100 patient-years (n=74) at a median fol
