A 62-year-old woman experienced an acute type A aortic dissection complicated with profound shock caused by acute myocardial ischemia. Intraoperative transesophageal echocardiography (TEE) identified a circumferentially dissected intimal flap at 5.5 cm above the aortic valve, prolapsing into the left ventricle through the aortic valve during diastole and obstructing both coronary ostia. Acute aortic dissection must be kept in mind when presented with myocardial ischemia and TEE is the most useful method for detecting a prolapsing cylindrical intimal flap.
一名62岁女性发生急性A型主动脉夹层，并伴有急性心肌缺血所致的严重休克。术中经食管超声心动图（TEE）显示主动脉瓣上方5.5 cm处有一环形剥离的内膜瓣，舒张期通过主动脉瓣脱垂入左心室，阻塞双侧冠状动脉开口。当出现心肌缺血时，必须考虑到急性主动脉夹层，而TEE是检测脱垂的柱状内膜瓣最有用的方法。
