AbstractA combined mechanical heart valve and vascular graft having a shortened transition area between the valve and the graft. The mechanical valve comprises a rigid circular annulus supporting internal leaflets. A stiffening ring surrounds the annulus and provides support for a sewing ring to attach the valve to the heart. The stiffening ring also captures a proximal end of the vascular graft between the stiffening ring and the annulus.
