Update on Prosthesis-Patient Mismatch Following Transcatheter Aortic Valve Replacement in Asian Patients.

ABSTRACT:

Background

Prosthesis-patient mismatch (PPM) after transcatheter aortic valve replacement (TAVR) is of greater concern in Asians, considering their relatively smaller annular sizes compared with Westerners. However, the prognostic significance of PPM in Asian populations has not been demonstrated.

Objectives

This study aimed to elucidate the prognostic value of PPM after TAVR in Asian patients.

Methods

Patients undergoing TAVR from October 2013 to December 2019 were enrolled from the OCEAN-TAVI (Optimized CathEter vAlvular iNtervention-Transcatheter Aortic Valve Implantation) registry. PPM was classified based on the indexed effective orifice area as severe (≤0.65 cm²/m²) or moderate (0.66-0.85 cm²/m²) in the general populat
