An 85 year-old woman underwent mitral valve replacement with Carpentier-Edwards PERIMOUNT（CEP）at the age of 72 because of rheumatic mitral stenosis. Thirteen years after its implantation, prosthetic valve dysfunction developed increasingly severe aortic valve stenosis and she underwent double valve replacement. Prolapse was found in one leaflet of the explanted CEP valve, while neither visible calcification nor tear was detected.
