A 56-year-old man, suspected of having ST-segment elevation myocardial infarction due to spontaneous coronary artery dissection, underwent emergency percutaneous coronary intervention. Although he had moderate aortic regurgitation with aortic root dilation and mild heart failure, it was controlled with medications. Two weeks after discharge, he was readmitted with severe heart failure due to severe aortic regurgitation and underwent an aortic root replacement. Intraoperative findings revealed that localized dissection of the sinus of Valsalva involved the right coronary artery, resulting in coronary artery dissection. In cases of spontaneous coronary artery dissection, attention should be paid to coronary artery dissection caused by localized aortic root dissection.
一名56岁男性，疑似因自发性冠状动脉夹层导致ST段抬高型心肌梗死，接受了紧急经皮冠状动脉介入治疗。尽管他有中度主动脉瓣反流伴主动脉根部扩张和轻度心力衰竭，但通过药物治疗得到了控制。出院两周后，他因严重主动脉瓣反流导致严重心力衰竭再次入院，并接受了主动脉根部置换术。术中发现，瓦尔萨尔瓦窦的局限性夹层累及右冠状动脉，导致冠状动脉夹层。在自发性冠状动脉夹层病例中，应注意由局限性主动脉根部夹层引起的冠状动脉夹层。
