Abstract
A natural tissue heart valve prosthesis mounted in a cloth-covered, generally anatomical stent is disclosed. The prosthesis includes an annular implantation flange attached to the exterior base portion of the stent between the inflow end and the outflow end of the stent base and a pericardium strip attached to at least a portion of the outflow rails of the prosthesis to generally inhibit abrasion between the cusps of the valve and the cloth covering of the stent structure.
