BACKGROUND: The arterial switch operation (ASO) represents a remarkable success story in the surgical treatment of cyanotic congenital heart disease. This study is designed to assess recent outcomes after the ASO in babies presenting with transposition of the great arteries (TGA) and Taussig-Bing anomaly (TBA). METHODS: One hundred twenty-five consecutive neonatal and infant ASOs were performed by 2 surgeons at Texas Children's Hospital between July 1, 1995 and October 1, 2003. Patients with TGA and TBA were offered ASO irrespective of patient size and associated cardiac malformations. Primary cardiac diagnoses included TGA with intact ventricular septum (TGA/IVS, n = 79, 63%), TGA with ventricular septal defect (TGA/VSD, n = 37, 30%), and Taussig Bing Anomaly (TBA, n = 9, 7%). RESULTS: With complete follow-up, we observed a 30-day mortality rate of 1.6% (n = 2) with 2 late deaths (1.6%), for an overall actuarial survival rate of 96.3% at 7 years. Although there was a significant incidence of complex coronary ostial origin and branching including single coronary (n = 8, 6.4%) and intramural coronary artery (n = 8, 6.4%), this was not associated with increased operative risk. All patients are fully saturated and NYHA functional class I at latest clinic visit (0.3 to 88.4 months postoperatively). There have been no late coronary events. Of 121 survivors, 7 patients (5.8%) have required cardiovascular reoperation at an average of 15.3 +/-11.7 months postoperatively (range, 3.6 to 30.6 months) for an actuarial freedom from reoperation of 90% at 7 years. CONCLUSIONS: Using current methodologies, the ASO can be performed safely and with a low incidence of need for reoperation on intermediate follow-up. Recent experience indicates operative survival rates approaching 100%.
