Extracardiac Fontan completion after the Kawashima procedure with a custom-made bifurcated graft

Abstract

The patient is a 5-year-old girl who underwent a previous Kawashima procedure with a left-sided bidirectional cavopulmonary anastomosis as a stage I palliation for her functional single ventricle. Her cardiac defect consisted of an unbalanced, right-dominant complete atrioventricular septal defect and a double outlet right ventricle. She also had heterotaxy syndrome with left isomerism, polysplenia, and an interrupted inferior vena cava with azygous continuation to a right-sided superior vena cava. Her native main pulmonary artery was left in continuity with her branch pulmonary arteries. She developed sinus node dysfunction, dilated ascending aorta, and progressive cyanosis. We proceeded with the completion Fontan using a bifurcated graft from both hepatic veins to the pulmonary arterial confluence, replacement of her dilated ascending aorta, disconnection of her native main pulmonary artery with excision of the pulmonary valve cusps, and placement of a dual-chamber epicardial pacemaker.
