title: Pedunculated aortic mural thrombus attached at unusual site of normal aorta presenting with acute myocardial infarction.
abstract: We report a rare case of thrombus formation in normal aorta causing myocardial infarction. A 44-year-old man who had no prothrombotic risk factors presented with acute myocardial infarction. Two-dimensional echocardiography revealed a hypoechoic homogenous mass occupying the left coronary sinus and attached at the nonatherosclerotic aorta. The mass seemed to cause myocardial infarction by occluding the left anterior descending artery with oscillating movement according to the cardiac cycles. After surgical resection, the histopathologic examination revealed the mass as an organized thrombus. This case implies that an aortic mural thrombus can form in a nonatherosclerotic aorta without any prothrombotic risk factors.
