title: Successful repair of double-outlet right ventricle, complete atrioventricular canal, and atrioventricular discordance associated with dextrocardia and pulmonary stenosis.
abstract: The association of complete atrioventricular canal with other complex congenital cardiac anomalies has represented a significant challenge for the cardiac surgion. The combination of double-outlet right ventricle with complete atrioventricular canal has been particularly difficult to correct, with no surgical successes having been reported until recently. This is a report of the first successful repair of double-outlet right ventricle, complete atrioventricular canal, and atrioventricular discordance (ventricular incersion) associated with common atrium, bilateral superior venae cavae, dextrocardia, and pulmonary stenosis. The specialized conduction tissue was identified by intracardiac electrophysiological mapping, and normal sinus rhythm was preserved. Postoperative cardiac catheterization showed excellent hemodynamics. One year postoperatively, the patient was attending school, playing swimming without difficulty, and taking no cardiac medications. This good result lends encouragement for considering total repair for similar patients with the combination of double-outlet right ventricle, complete atrioventricular canal, and other associated congenital cardiac anomalies.
