Analysis of Surgical Outcome in Complex Double-Outlet Right Ventricle With Heterotaxy Syndrome or Complete Atrioventricular Canal Defect

Atrioventricular valve regurgitation, pulmonary venous obstruction, and neonatal presentation are risk factors for mortality in patients with complex double-outlet right ventricle. Early surgical intervention in symptomatic neonates and infants, including those with pulmonary venous obstruction, may reduce mortality and improve outcome after staged operation.
