We report the case of a four-year-old boy with pulmonary atresia (PA) and ventricular septal defect (VSD) associated with MAPCAs who had a complete repair two times. He developed 21 months later stenosis at the origin of both pulmonary arteries. The conventional interventional catheterization approaches were not available due to femoral vein thrombosis and severe transient complete atrioventricular block due to the manipulations to catheterize the left pulmonary artery. The stenoses were treated by implant of stents using a surgical access to the proximal portion of a Contegra valved conduit (Medtronic, Inc., Minneapolis, MN, USA) by sternotomy.
