A Newly Developed Polyurethane Prosthetic Heart Valve

Abstract

Polyurethane prosthetic heart valve tried to imitate the geometry of native valve that might perhaps show better performance which is close to natural valve. However, the geometry of natural valve is very complex and there are variety of parameters can affect performances of the valves. This study has simplified the geometry of natural valve so that there are only four parameters needs to be considered. The four parameters include the fundamental curve, the free edge angle, the valve height, and the leaflet thickness. The study investigated the influence of these four parameters on biomechanics of the polyurethane prosthetic valves.
