title: [A case report of St. Jude medical aortic valve prosthesis thrombosis].
abstract: We report a case of successful semi-emergent redo aortic valve replacement for thrombosed prosthetic valve. Patient was a 59-year-old male who had undergone aortic valve replacement of St. Jude Medical prosthetic valve and open mitral commissurotomy 14 years ago. He suffered from pneumonia with hemosputum and admitted a neighbor hospital. But he was reffered to our medical center because of progressing dyspnea. We found the immobility of one of the leaflets of the prosthetic valve by cinefuluoroscopy. He was also diagnosed as prosthetic valve thrombosis and mitral valve restenosis using ultrasonic echocardiography. The thrombi were developed on the hinge of one of the leaflets, and they might be formed during the time he had got inappropriate anticoagulation therapy at the former hospital. We emphasise the importance of strict anticoagulation control for the patients valve replaced.
