A floating thrombus in the ascending aorta complicated by acute myocardial infarction

摘要

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 his-tological 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.
