title: [Re-operation of an aortic pericardial bioprosthesis 23-years after implantation; report of a case].
abstract: A 49-year-old female suffered from dyspnea on exertion and jaundice from June, 2009. She had undergone aortic valve replacement with Carpentier-Edwards pericardial bioprosthesis due to active infectious endocarditis 23-years previously. The echocardiography showed severe aortic stenosis with moderate regurgitation. She was diagnosed as having prosthetic valve malfunction. Re-replacement of the aortic valve with mechanical valve was successfully performed. As far as we can see, this is one of the longest-term cases of implantation of pericardial bioprosthesis.
