ABSTRACT:
A method of treating heart valve dysfunction in a human patient in which the dysfunctioning valve is replaced with a novel bioprosthesis. The novel bioprosthesis comprises a porcine pulmonary valve, which has preferably been treated to fix and also sterilize the valve tissue. The porcine pulmonary valve may either be stent mounted to facilitate its surgical implantation into the patient, or it may be unstented to reduce the possibility of embolism and thrombosis.
