Abstract

The literature describes multiple approaches for the repair of stenosed branch pulmonary arteries. Regardless of the technique, restenosis is undesirably and notoriously common. We describe a case of severe left pulmonary artery stenosis repaired with a novel technique in consideration of factors leading to restenosis. The native main pulmonary artery was transected and turned down to create a direct anastomosis with the left pulmonary artery. The child had a normal sized main pulmonary artery with tricuspid atresia and pulmonary atresia with ductus arteriosus feeding the severely stenosed left pulmonary artery. Our novel technique resulted in hemodynamically gratifying results with a tension free tissue-tissue anastomosis with potential for growth.
