Transcatheter Superior Cavopulmonary Shunt Completion After Pulmonary Artery Septation.

We present the case of a 16-month-old patient with tricuspid atresia and absent pulmonary valve who underwent staged single ventricle palliation, ultimately to a unidirectional superior cavopulmonary anastomosis (Glenn) to the right pulmonary artery and a central shunt to a hypoplastic left pulmonary artery. The pulmonary arteries were septated with a thin patch of Gore-Tex at that surgery in anticipation of a transcatheter superior cavopulmonary shunt completion at a later date. She returned to the cardiac catheterization laboratory about 12 months later and underwent uncomplicated shunt completion. There are no other reports of transcatheter superior cavopulmonary anastomosis shunt completion in a pediatric patient in the literature.
