TCT-756 Incidence of Patient Prosthesis Mismatch Following Native and Valve-in-Valve Transcatheter Aortic Valve Replacement Based on Indexed Aortic Valve Area Compared to Energy Loss Index

Abstract

Severe patient-prosthesis mismatch (PPM) is defined as an indexed aortic valve area (AVAi) <0.65 cm2/m2. Its effect on clinical outcomes may be unfavorable following transcatheter aortic valve replacement (TAVR). However, its incidence may be exaggerated when using AVAi, especially following valve-
