Summary
Echocardiographic evidence of systolic aortic regurgitation following a Damus-Kaye-Stansel procedure for palliation of complex double-outlet right ventricle is presented. This procedure directs left ventricular output to the aorta through a proximal main pulmonary artery-aortic anastomosis and utilizes a valved conduit between the right ventricle and distal pulmonary artery. Postoperative Doppler and color flow echocardiographic findings revealed systolic and diastolic regurgitation from the native aorta to the right ventricle. Aortic valve closure at the time of the original Damus-Kaye-Stansel procedure would eliminate regurgitant flow and circumvent subsequent closure of this valve due to increased systolic aortic regurgitation.
