Biventricular Repair of Pulmonary Atresia After Fontan Palliation.

Abstract

Fontan palliation is used when biventricular repair (BVR) is not possible. Early outcomes are acceptable; however, the long-term sequelae include protein-losing enteropathy, declining functional status, increased pulmonary vascular resistance, heart failure, and hepatic and renal dysfunction. These adverse events are characteristic of persistent venous hypertension and may be avoided if restoring biventricular circulation is possible. Arrhythmias are a common adverse event, particularly in patients with an atriopulmonary connection, which may lead to acute decompensation and early death. We describe a 30-year-old woman who underwent successful BVR for pulmonary atresia with intact ventricular septum and demonstrate that where favorable anatomy exists with a failing Fontan, BVR should be considered.
