Tricuspid Leaflet Aortic Valve Prosthesis

Abstract
The theoretical and practical advantages of the flexible-leaflet prosthetic aortic valve make it worthy of continued development. Laboratory and clinical experience with a precision-molded, single-unit, tricuspid silicone rubber prosthesis suggest that the problems of materials, construction, and performance have been overcome. The use of a suitable elastomer in a precision casting with an anticlotting surface coating has resulted in a leaflet prosthesis the long-term functional performance of which should compare favorably with any device currently in use.
