title: Left ventricle-to-ascending aorta communication complicating composite graft repair undetected by aortography: diagnosis by transesophageal echocardiography.
abstract: 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.
