Treatment options for transposition of the great arteries with ventricular septal defect complicated by pulmonary vascular obstructive disease

The arterial switch operation is the procedure of choice for patients with isolated transposition of the great arteries or those with associated atrial and/or ventricular septal defects. After the development of pulmonary arterial hypertension, the surgical options for patients with a late presentation include either retraining the left ventricle by pulmonary artery banding followed by an arterial switch operation or palliative atrial or arterial switch, with or without medical management of pulmonary hypertension. We present a case with D-transposition of the great arteries with ventricular septal defects and irreversible pulmonary arterial hypertension who improved after a palliative atrial switch operation.
