A 42-year-old male was admitted because of chest discomfort, palpitation, and dyspnoea. He had suffered from anterior myocardial infarction at the age of 29. Moderate-to-severe left ventricular (LV) dysfunction was noted from then. Four months before admission, transthoracic echocardiography revealed LV thrombus-like lesion on the interventri-cular septum to LV apex with severe LV dysfunction (LVEF = 25-30% by visual estimation) (Figure A). Coumadin was admitted immediately, and INR was maintained in the range of 2-3 thereafter. At the time of admission, the size of mural thrombus was increased compared with previous evaluation (Figure 8). Orthotopic cardiac transplantation was performed to reduce the risk of embolization and to ameliorate symptoms of heart failure. The final pathologic diagnosis was malignant fibrous histiocy-toma with negative resection margin.
