Outcomes of the arterial switch operation in patients with Taussig-Bing anomaly

Abstract

Background: The arterial switch operation (ASO) is associated with poorer outcomes in patients with Taussig-Bing anomaly (TBA) compared with transposition of the great arteries (TGA). We describe the outcomes after ASO in patients with TBA at a single institution. Methods: Between 1983 and 2009, 57 patients with TBA underwent the ASO at the Royal Children's Hospital in Melbourne. Results: Hospital mortality was 5.3% (3 of 57). Larger weight at operation (p = 0.015), pulmonary artery banding prior to ASO (p = 0.049) and concurrent pulmonary artery banding (p = 0.049) were risk factors of early death. Actuarial survival was 94% at 15 years. Follow-up was 84% complete with a mean follow-up of 9..
