Aortic valve replacement (AVR) is the gold standard for the treatment of severe symptomatic aortic stenosis. Complications directly related to surgical procedure are relatively infrequent. Coronary ostial stenosis is, generally, referred as late complication. Anecdotal reports concern coronary ostial stenosis as acute complication. A unique fatal case of intraoperative, bilateral coronary ostial obstruction by prosthetic valve leading to an extensive myocardial infarction is reported. Surgeons must have a high level of vigilance regarding the occurrence of acute myocardial ischemia and sudden death soon after AVR.
主动脉瓣置换术（AVR）是治疗严重症状性主动脉瓣狭窄的金标准。与手术直接相关的并发症相对较少见。冠状动脉口狭窄一般被认为是晚期并发症。有报道称冠状动脉口狭窄为急性并发症。本文报告了一例独特的术中致命病例，即由人工瓣膜引起的双侧冠状动脉口阻塞，导致广泛的心肌梗死。因此，外科医生在进行 AVR 后必须高度警惕急性心肌缺血和猝死的发生。
