Long-Term Outcomes After Extracardiac Fontan Takedown to an Intermediate Palliative Circulation

Takedown to a superior cavopulmonary connection is an effective treatment option and, in some patients, acts as a bridge to subsequent redo Fontan completion or heart transplantation. An extended intermediate palliative circulation is tolerated for several years with reasonable oxygen saturation levels at rest. In our experience, an early takedown strategy to a superior cavopulmonary connection is the treatment of choice for acute Fontan failure.
