Late Heart Transplantation in Hypoplastic Left Heart Syndrome With Intact Atrial Septum.

This case report describes 2 patients born with hypoplastic left heart syndrome and an intact atrial septum who underwent a strategy of immediate extracorporeal membrane oxygenation and left atrial decompression followed by hybrid Norwood palliation as a bridge to further palliation. Heart transplantation was ultimately performed in these 2 patients with persisting pulmonary vascular resistance abnormalities.
