Abstract
Anomalous origin of the right pulmonary artery from the ascending aorta (AORPA) is a rare congenital cardiac malformation. Clinical manifestations usually appear in infants or, more rarely, in newborns and include respiratory distress or congestive heart failure due to increased pulmonary resistance. Primary total correction of AORPA reportedly can result in excellent survival with a low incidence of reintervention. We report here two cases of staged repair of AORPA. Case 1 involved a 25-day-old girl who had a complicating respiratory syncytial (RS) virus infection. RS virus infection in children with congenital heart disease is associated with high mortality and morbidity, and cardiac surgery performed with cardiopulmonary bypass during symptomatic RS virus infection is associated with a high risk of postoperative complications, especially postoperative pulmonary hypertension. Therefore, we decided that the initial palliation should consist of right pulmonary artery banding, and total correction was achieved 2 months later. Case 2 involved an almost 2-month-old girl who initially underwent right pulmonary artery banding due to severe pulmonary hypertension, and total correction was achieved 13 days later. Both patients were discharged in good condition without any clinical symptoms. us, right pulmonary artery banding appears to be a good surgical option for patients with AORPA and complicated condition.
