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.
我们报告了一例罕见的正常主动脉血栓形成导致心肌梗死的病例。一名 44 岁的男性，没有血栓形成的危险因素，出现了急性心肌梗死。二维超声心动图显示左冠状窦内有一低回声均质肿块，附着于非粥样硬化主动脉。根据心动周期，该肿块似乎通过阻塞左前降支导致心肌梗死，且有摆动运动。手术切除后，组织病理学检查显示肿块为已机化的血栓。该病例提示，无任何血栓形成危险因素的情况下，非粥样硬化主动脉也可形成主动脉壁血栓。
