Extra-anatomic right ventricle to pulmonary artery conduit: the apical-aortic equivalent for complex right ventricular outflow tract reconstruction.

Abstract

We describe the case of a 22-year-old with tetralogy of Fallot, who underwent complete repair with ventricular septal defect closure and right ventricle to pulmonary artery conduit placement. She has undergone numerous subsequent conduit changes, each complicated by early stenosis and failure. Unfortunately, serial conduit changes can become increasingly challenging. While extra-anatomic conduits have been described for complex left ventricular outflow tract obstruction, they have not been described for right-sided obstruction. Herein, we present a patient who underwent successful placement of an extra-anatomic valved right ventricle to pulmonary artery conduit in the setting of complex right ventricular outflow tract obstruction.
