Abstract:
A 37-year-old male was transferred to our hospital with a diagnosis of acute myocardial infarction and a mass in the ascending aorta. Echocardiography revealed dyskinesia on the left ventricular apex and a floating mass lesion just above the aortic valve. Acute myocardial infarction was considered to be caused by embolism from the floating mass in the ascending aorta. Emergency surgery was successfully performed and histological examination showed the extirpated mass in the ascending aorta was thrombus. The patient has been well on oral anticoagulant and no recurrence has been seen on echocardiogram 4 years after the operation.
