Closure of aorto-right ventricular tunnel with Amplatzer duct occluder II

Abstract

Aorto-right ventricular tunnel (ARVT) is a very rare, congenital, abnormal extracardiac channel that connects the ascending aorta at or above the sinotubular junction to the cavity of the right ventricle. Only 16 cases have been reported thus far in the English literature. We report the first transcatheter closure of ARVT with the Amplatzer duct occluder II in an infant, with both coronary arteries arising from the left coronary sinus and with biventricular apical non-compaction.
