Anterior translocation of the right pulmonary artery for airway obstruction caused by pulmonary hypertension.

Both the bronchi are often severely squeezed by the dilated pulmonary artery in infants with ventricular septal defect and pulmonary hypertension. To relieve the considerable residual airway obstruction, the right pulmonary artery is translocated anteriorly to the ascending aorta concomitantly with the intracardiac repair. This technique is a useful procedure for infants with intractable respiratory failure caused by a dilated pulmonary artery.
