A case with severe left main trunk (LMT) stenosis nine months after aortic valve replacement was presented. The patient, 57-year-old female, underwent aortic valve replacement with a tilting disk valve (Omnicarbon 21 A). Her postoperative course was uneventful, but angina pectoris developed after nine months. Coronary angiography was performed and revealed 99% LMT stenosis. Operation was performed with OTCA to LMT and with a saphenous vein graft to left anterior descending artery. Coronary artery stenosis following aortic valve replacement may be dangerous and it must be treated as soon as the diagnosis is established.
本文报告1例主动脉瓣置换术后9个月发生严重左主干（LMT）狭窄的病例。患者为57岁女性，接受了倾斜碟瓣（Omnicarbon 21 A）主动脉瓣置换术。术后恢复顺利，但9个月后出现心绞痛。行冠状动脉造影显示左主干狭窄99%。对左主干行非体外循环冠状动脉搭桥术（OTCA），并对左前降支行大隐静脉移植术。主动脉瓣置换术后的冠状动脉狭窄可能很危险，一旦确诊就必须立即治疗。
