Outcome After Fontan Failure and Takedown to an Intermediate Palliative Circulation

Fontan takedown can provide effective stabilization of the acutely or subacutely failing Fontan circulation, although a substantial number of patients die early despite Fontan takedown. Subjects surviving the perioperative period can often undergo uneventful redo Fontan. A thorough evaluation for treatable abnormalities should be performed in all patients with a failing Fontan circulation and in patients who undergo Fontan takedown.
