Transcatheter closure of ostium secundum atrial septal defect in congenitally corrected transposition of great arteries with visceral situs inversus and dextrocardia: Rationale and technical challenges.

Abstract

Congenitally corrected transposition of the great arteries (CC-TGA) may occur in isolation or may be associated with defects in the ventricular septum and stenosis of the pulmonary outflow tract. A large ostium secundum atrial septal defect (ASD) as the only other anomaly is rare in CC-TGA. We report successful use of an Amplatzer septal occluder to close an ASD in a patient with visceral situs inversus, dextrocardia, and CC-TGA.
