Successful Operation for Acute Mitral Regurgitation due to Ruptured Chordae in a Patient Suffering from Infective Endocarditis Complicated with Preoperative Cerebral Infarction and Subarachnoid Hemorrhage / 日本心臓血管外科学会雑誌

ABSTRACT

The following paper describes mitral valve replacement in a 48-year-old man. He had been perfectly well until he was brought to the emergency room because of fever and impaired consciousness. Computed tomography revealed subarachnoid hemorrhage. Magnetic resonance imaging showed multiple cerebral infarctions. Echocardiography revealed a large vegetation (25×20 mm) under his mitral valve and mild mitral regurgitation. He was treated with adequate antibiotics for several days. On the 11th admission day, his condition worsened dramatically. We found acute mitral regurgitation due to ruptured chordae. After IABP was inserted, an urgent operation was performed. After the operation, he improved gradually. He was discharged 50 days postoperatively in a satisfactory condition without any critical complications. This report describes an experience of successful operation for acute mitral regurgitation due to ruptured chordae in a patient who suffered from infective endocarditis complicated with preoperative cerebral infarction and subarachnoid hemorrhage.
