Preparatory stage of interventional extracardiac Fontan

Abstract

The extracardiac Fontan can be completed as an interventional procedure when the preparatory stage for Fontan completion is performed at the time of the bidirectional Glenn operation. In this video tutorial, we present the technique for the preparatory stage of an interventional extracardiac Fontan. The interventional aspect offers the advantage of avoiding a redo sternotomy, which involves the risk of cardiac injury, injury to the mediastinal collaterals due to the single-ventricle physiology, the acquired deranged coagulation that may incur morbidity associated with sternal re-entry, and the problems pertinent to cardiopulmonary bypass and/or cardioplegic arrest in this subset of patients.
