Radiofrequency perforation and cutting balloon septoplasty of intact atrial septum in a newborn with hypoplastic left heart syndrome using transesophageal ICE probe guidance.
Newborns with hypoplastic left heart syndrome and intact atrial septum present an emergent and unique challenge to a children's heart center. This case report describes new transcatheter techniques (use of radiofrequency energy to perforate the atrial septum followed by cutting balloon and static balloon septoplasty) and novel use of a transesophageal ICE probe.
