Prosthetic Mechanical Valves
Prosthetic Mechanical ValvesEarly mechanical prosthetic heart valves were ball valves. In 1952, Dr. Charles Hufnagel implanted the first ball and cage valve into a patient with aortic valve insufficiency. Although the design of mechanical prosthetic valves has progressed significantly over the past 50 years, ball and cage valves are still the valve of choice by some surgeons.Björk-Shiley designed the first tilting disc, or single leaflet, valve around 1969. Those valves used a tilting disc occluder that was held in place by a retaining strut. However, the development of the bileaflet valve by St. Jude Medical in 1978 has led to the predominance of this type of bileaflet valve in the mechanical valve market.
