A 34-year-old woman was hospitalized with shortness of breath and chest tightness and pain. She had undergone aortic valve replacement for aortic stenosis at the age of 18 years. Transthoracic echocardiography showed left ventricular asynergy and a high aortic valve pressure gradient. Thus, structural valve deterioration was diagnosed. Coronary computed tomography and coronary angiography revealed left main trunk ostial stenosis that had caused acute anteroseptal myocardial infarction. Urgent surgery revealed pannus formation around the prosthetic valve and covering the ostium of the left main trunk. A Bentall procedure and coronary artery bypass grafting were performed. The postoperative course was uneventful.

一名 34 岁女性因呼吸急促、胸闷和疼痛住院。她在 18 岁时因主动脉瓣狭窄接受了主动脉瓣置换术。经胸超声心动图显示左心室无协同作用和高主动脉瓣压力梯度。因此，诊断出结构性瓣膜恶化。冠状动脉计算机断层扫描和冠状动脉造影显示左主干口狭窄，导致急性前间壁心肌梗死。紧急手术显示在人工瓣膜周围形成血管翳并覆盖左主干口。进行了 Bentall 手术和冠状动脉旁路移植术。术后过程很顺利。
