title: [Redo double valve replacement in a patient with bioprosthetic valve malfunction by pannus formation; report of a case].
abstract: A 76-year-old female, who had received Carpentier-Edwards perimount (CEP) pericardial bioprostheses for aortic and mitral valves 6 years before, was diagnosed with reduced mobility of the valvular cusps by echocardiogram 2 years after the surgery. The symptoms of heart failure gradually aggravated. Significant stenosis and regurgitation were observed of the prosthetic valves, and a second surgery was performed. Calcification and severe pannnus formation were observed of both CEP valves that were excised.
