The management of dextrotransposition of the great arteries with left ventricular outflow tract obstruction continues to evolve. Even when large intracardiac shunts are present, it remains a lethal cyanotic congenital heart disease if it is not surgically corrected soon after birth. We present our experience with a 25-year-old woman who presented with transposition of great arteries with severe left ventricular outflow tract obstruction and underwent a successful single-stage arterial switch operation with preservation of aortic and pulmonary valves.
