Arterial switch with pulmonary artery banding: A staged repair strategy for transposition of great arteries with complex intracardiac anatomy

Objective: We present initial results of arterial switch operation (ASO) with pulmonary artery banding (PAB), followed by intracardiac repair for patients with transposition of great arteries (TGA) associated with unusually complex intracardiac anatomy. Methods: Between 2000 and 2023, these patients (1.9% of 1744 TGA in our institution) were retrospectively reviewed. Staged repair was either strategy A (2000-2018; 1. PAB, 2. ASO + intracardiac repair) or strategy B (2014-2023; 1. ASO + PAB, 2. Intracardiac repair); aortic arch repair could be associated. We compared those strategies. Results: = 1). Conclusions: Early ASO + PAB procedure, over PAB only, for patients with TGA with complex intracardiac anatomy leads to early anatomical repair with greater oximetry, less unplanned reoperation, and easier short-term outcomes.
