Arterial switch operation for Taussig-Bing anomaly with aortic arch obstruction.

The short-term survival rate after single-stage correction of Taussig-Bing anomaly with aortic arch obstruction remains favorable. However, some cases are encountered occasionally in which single-stage correction was not performed during the neonatal period. Accordingly, we evaluated the midterm outcomes of different surgical strategies. Seven patients who underwent an arterial switch operation and intraventricular rerouting as definitive surgery between 2007 and 2017 were investigated. Of these 7 patients, 3 had undergone previous pulmonary artery banding and aortic arch reconstruction. The median body weight at definitive surgery was 3.3 kg (range 2.9-8.3 kg). At definitive surgery, the arrest time for single-stage correction (162.3 ± 21.7 min) was significantly shorter than that of staged repair (206.3 ± 5.1 min, The surgical outcomes of both single-stage correction and staged correction for Taussig-Bing anomaly with aortic arch obstruction are excellent. Both strategies produce similar changes in the diameter and regurgitation grade of the neoaortic and neopulmonary valves.
