Use of a self-expanding custom-made stent graft to treat lateral tunnel leak, stenosis, and fenestration in the Fontan pathway

Abstract

A 12-year-old girl with hypoplastic right heart, double inlet left ventricle, and transposition of the great arteries had a lateral tunnel Fontan operation 8 years previously. She developed symptoms related to a combination of stenosis in the inferior caval venous pathway, a fenestration, and leak in the lateral tunnel. These were successfully treated with a custom-made stent graft.
