Mechanical Prosthetic Valves

Abstract

Mechanical valves offer excellent durability and hemodynamics at both the aortic and mitral position but require lifelong anticoagulation. The majority of mechanical valves utilized today are bileaflet valves composed of pyrolytic carbon, and most of the newer generation valves are designed to reduce thrombogenicity and improve hemodynamics. With the increasing durability of bioprosthetic valves and the widespread acceptance of transcatheter aortic valve replacement, the indications for mechanical valves are becoming narrower. Nonetheless, mechanical valves remain an excellent option for young patients who can tolerate anticoagulation because of their unmatched durability.
