Approach for surgical correction of pulmonary artery coarctation without cardiopulmonary bypass.

Pulmonary artery coarctation often happens in patients with pulmonary atresia. The correction has been usually performed using cardiopulmonary bypass and during the neonatal period, influencing pulmonary artery development and prognosis. Three patients with pulmonary atresia with PDA underwent correction using median sternotomy without cardiopulmonary bypass. The PDA maintained the arterial saturation during Blalock Taussig anastomoses upon the contralateral pulmonary artery. Arterioplasty was performed using an autologous pericardium with 7-0 PDS running suture and saturation was maintained by Blalock shunt. All patients presented good follow-up and where discharged with good enlargment of coarctation area.
