title: Subaortic stenosis following anatomic correction for transposition of the great arteries.
abstract: The authors present a case report of a 12-year-old boy with diagnosis of transposition of the great arteries and ventricular septal defect, who underwent an arterial switch operation plus closure of the septal defect. On follow-up, left ventricular outflow tract obstruction was detected, initially mild. Last year, he started complaining of fatigue on exercise. Severe subaortic stenosis was diagnosed and surgical repair was performed with good results. Subaortic stenosis is a rare complication on follow-up of patients who have undergone an arterial switch operation, particularly those with transposition of the great arteries and ventricular septal defect.
