Transcatheter Device Closure of a Perimembranous Ventricular Septal Defect in Congenitally Corrected Transposition of the Great Arteries

The majority of patients with congenitally corrected transposition the great arteries, also known as arteries {S,L,L} have ventricular septal defects (VSD), most commonly perimembranous VSD (pmVSD). Transcatheter device closure pmVSD in these has not been widely described. We present a case L-TGA an Amplatzer Duct Occluder II (ADOII) using deployment starting subpulmonary left ventricle. demonstrates some technical advantages ADOII for closure, specifically its low profile, symmetric shape, and soft material. These characteristics are advantageous closing conventional but especially useful challenging anatomic substrates.
