The usual cause of left main coronary artery obstruction is atherosclerotic occlusion resulting from plaque rupture and subsequent thrombus formation. In previously reported cases, tumor embolization into the coronary arteries caused sudden death and was detected only at autopsy. Herein, we report an unusual presentation of cardiac papillary fibroelastoma of the aortic valve in a 62-year-old man. The fibroelastoma caused a left main coronary artery embolus and symptoms of acute coronary syndrome. The fibroelastoma was successfully excised during a valve-sparing surgical procedure. We believe that this is the 1st report of tumor embolization to the left main coronary artery--and in a living patient.
左主冠状动脉阻塞的常见原因是斑块破裂及随后血栓形成导致的动脉粥样硬化闭塞。在既往报道的病例中,肿瘤栓塞至冠状动脉可导致猝死,且仅在尸检时被发现。在此,我们报告一名62岁男性主动脉瓣心脏乳头肌纤维弹性瘤的罕见表现。该纤维弹性瘤导致左主冠状动脉栓塞及急性冠状动脉综合征症状。在保留瓣膜的手术过程中成功切除了该纤维弹性瘤。我们认为这是左主冠状动脉肿瘤栓塞的首例报道——且是在一名在世患者中的报道。
