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.
