title: [A case report of primary rhabdomyosarcoma of the heart treated with mitral valve replacement].
abstract: We report a case of rhabdomyosarcoma involving the mitral valve of a 57-year-old female. She was referred to our hospital for progressive orthopnea and edema. Chest X-ray showed marked cardiomegaly and pulmonary congestion. Echocardiogram revealed solid mass in left atrium involving the mitral valve. Emergency operation was required because of acute heart failure. At the operation, the mitral orifice was obstructed by the tumor arising from the left atrium. After partial resection of the left atrium, mitral valve replacement with a Carpentier-Edward prosthesis was performed. Subsequently microscopic examination diagnosed as rhabdomyosarcoma. She died three months after the operation of heart failure probably due to progression of the remnant of the tumor. This, to our knowledge, is the first case of mitral valve replacement for a primary rhabdomyosarcoma of the heart in Japan.
