title: A case of Carpentier-Edwards pericardial bioprosthesis in mitral position explanted 22 years after implantation.
abstract: A case of Carpentier-Edwards PERIMOUNT (CEP) mitral pericardial bioprosthesis explanted 22 years after the valve replacement is reported. This patient underwent the previous replacement at the age of 50. The extracted bioprosthesis showed three rigid leaflets, one of which had a tear causing severe mitral regurgitation. The X-ray demonstrated calcification of varied extent among these leaflets, ranging from none to severe. When leaflet calcification is suppressed, perhaps the lifespan of a CEP valve can be prolonged more than previously expected. When a literature search was conducted, this case was found to represent the longest reported interval from the implantation of a CEP valve in the mitral position to the explantation as a result of severe mitral regurgitation caused by structural valve deterioration (SVD).
