BACKGROUND: This study was conducted to evaluate the surgical results of the arterial switch operation for Taussig-Bing variants, at a single institution in a lower-middle income country. METHODS: Between June 2010 and December 2018, all consecutive patients diagnosed with Taussig-Bing variants who underwent the arterial switch operation and ventricular septal defect closure were included in the study. RESULTS: A total of 72 patients of Taussig-Bing variants underwent arterial switch operation and ventricular septal defect closure. There were 10 early deaths (13.9%) and 2 late deaths (2.8%). Intraoperative ventricular septal defect enlargement (hazard ratio [HR] 7.23, 95% confidence interval [CI] 3.1294-16.7167; p < .001), secondary aortic cross-clamping (HR 28.38, 95% CI 4.8427-166.3484; p < .001), postoperative pneumonia (HR 5.64, 95% CI 1.2724-24.9917; p = .023), and postoperative sepsis (HR 5.28, 95% CI 1.3512-20.6553; p = .017) were risk factors for overall mortality by competing risk analysis. Sixty patients (83.3%) required septoparietal trabeculation division/resection during the arterial switch operation in an attempt to avoid right ventricular outflow tract obstruction. The reoperation rate for right ventricular outflow tract obstruction at last follow up was 6% (three patients). The estimated freedom from reoperation for right ventricular outflow tract obstruction at 1, 5, and 9 years was 98.3%, 91.9%, and 91.9%, respectively. CONCLUSIONS: The results of arterial switch operation for Taussig-Bing variants were satisfactory in the operative setting of a lower-middle income country, and performing extensive septoparietal trabeculation division might reduce the reintervention rate for right ventricular outflow tract obstruction in these patients.
