Transcatheter valve repair in congenitally corrected transposition of the great arteries

Abstract

Introduction In congenitally corrected transposition of the great arteries (CCTGA) the right ventricle (RV) is the systemic ventricle. RV dysfunction and significant regurgitation of the systemic tricuspid valve are common and associated with worse outcomes. Management of tricuspid regurgitation (TR) in CCTGA is challenging. In acquired cardiovascular disease, percutaneous repair of mitral valve regurgitation (MR) is established. Data on CCTGA with TR are limited1. We report our experience with this technique in these patients. Methods CCTGA patients with moderate-severe TR were eligible if surgery was deemed high-risk. Interventional therapy was offered, and patients provided written informed consent. ...
