Abstract
A biscuspate cardiac valve prosthesis for use in human clinical medicine as a mitral valve graft. The valve has a support ring with an arched crosspiece containing apertures or a single longitudinal aperture along its length, joined at its ends to the lower portion of the support ring. Valve flaps are attached to both sides of the crosspiece, the opposite edges of the flaps being able to move freely during functioning of the valve. When the valve is closed, the flaps abut the inner surface of the support ring in a low dome profile.
