Abstract
A prosthetic heart valve constructed of hemo-compatible materials that is anatomically and functionally similar to the natural aortic valve is disclosed which reduces or eliminates the occurrence of many of the complications found in the use of prior art prosthetic valves. The heart valve is a trileaflet type which has its formed leaflets heat set in a partially open position to reduce pressure required to open the leaflets in response to blood flowing therethrough.
