Duplication of the Mitral Valve Associated with Endocardial Cushion Defect: Report of a Case with Mitral Valve Replacement

Abstract

A case of double orifice mitral valve is presented, in which the patient under went previous closure of an ostium primum defect and repair of a mitral cleft, eventually producing severe mitral regurgitation requiring prosthetic valve re placement six years later. The nature of the lesion and surgical alternatives are discussed. We conclude that valve replacement should be the treatment of choice in severe mitral regurgitation associated with double orifice mitral valve.
