prosthetic heart valve

A substitute valve used to replace a diseased valve. There are two main types of prostheses: those made from biological tissues, e.g., the heart valves of animals, esp. pigs, and those made from biocompatible materials, e.g., metals or polymers. Biocompatible mechanical valves may be constructed in a variety of ways, e.g., from a ball that moves up and down in a cage; with bileaflet valves that close in the midline; or with a single leaflet (which tilts to open and close).
