Sutureless versus Stented Bioprostheses for Aortic Valve Replacement: The Randomized PERSIST-AVR Study Design

摘要

Introduction Sutureless biological valves for surgical aortic valve replacement (SAVR), characterized by the absence of anchoring sutures at the aortic annulus, are gaining popularity because of ease and reproducibility of implant, shorter operating times, and enhancement of minimally invasive approaches. The stentless configuration of the sutureless valve was designed to achieve optimal hemodynamic performance.
