Introduction

Prosthesis-patient mismatch (PPM), particularly when

moderate or severe, has been associated with increased

long-term mortality after surgical aortic valve

replacement (SAVR). However, this relationship remains

controversial in the context of transcatheter aortic valve

replacement (TAVR). Despite ongoing debate over its

clinical impact, avoiding moderate and severe PPM is

considered best practice among cardiac surgeons.
