Trends in SAVR with biological vs. mechanical valves in middle-aged patients: results from a French large multi-centric survey.

Background/introduction: Currently, despite continued issues with durability ( 1), biological prosthetic valves are increasingly chosen over mechanical valves for surgical aortic valve replacement (SAVR) in adult patients of all ages, at least in Western countries. For younger patients, this choice means assuming the risks associated with a redo SAVR or valve-in-valve procedure.

Purpose: To assess the use of mechanical vs.
