A new prosthetic heart valve has a standard mounting ring with a centrally located occluder and a single piece biological circular flat membrane with a central aperture adapted to be selectively closed by the occluder.

The flexible membrane leans against the occluder in the closed position, and deflects axially away from the occluder when open. The occluder is held in position by spokes attached to the mounting ring, which also supports the membrane along its full periphery with one continuous readily accessible suture attachment.
