A 57-year-old man underwent composite ascending aortic conduit and prosthetic aortic valve repair of a sinus of Valsalva aneurysm. The patient's course was complicated by recurrent aneurysm formation caused by a communication between the left ventricular outflow tract and the ascending aorta outside the conduit. Transesophageal echocardiography documented the anatomic and functional characteristics of this complication, whereas aortography failed to demonstrate them. Findings at surgery confirmed the transesophageal echocardiogram results of a left ventricular outflow tract to aorta communication, a normal prosthetic aortic valve, and an intact distal anastomosis of the conduit with the aorta. Transesophageal echocardiography is a useful modality for the evaluation of composite graft repairs of the aortic valve and ascending aorta.
一名57岁男性接受了升主动脉复合管道及人工主动脉瓣修复术，以治疗瓦氏窦瘤。患者的病程因管道外左心室流出道与升主动脉之间的交通导致复发性动脉瘤形成而复杂化。经食管超声心动图记录了这一并发症的解剖和功能特征，而主动脉造影未能显示这些特征。手术结果证实了经食管超声心动图的结果，即存在左心室流出道至主动脉的交通、人工主动脉瓣正常以及管道与主动脉的远端吻合口完整。经食管超声心动图是评估主动脉瓣和升主动脉复合移植物修复的一种有用方法。
