Transcatheter Revision of Fontan Circulation by Connecting the Classical Glenn Circulation With the Inferior Vena Cava and Pulmonary Artery Circulation

Abstract

Patients with single-ventricle physiology require staged palliation. Additional interventions may be required due to Fontan failure, formation of collaterals or pulmonary arteriovenous malformations (PAVMs). Transcatheter interventions are preferable in this setting to avoid the risks of redo-sternotomy, and cardiopulmonary bypass. We present our experience with transcatheter revision of Fontan circulation in a cyanotic adult congenital heart patient with hypoplastic left heart syndrome (HLHS). Transcatheter Fontan completion may be a feasible option in patients with favorable anatomy and hemodynamics with optimal outcomes.
