Double Root Switch Repair for Taussig-Bing Anomaly.

The double root switch was used to repair a Taussig-Bing anomaly in a two-month-old child. The surgery was performed with translocation of the aortic root to the left ventricular outflow tract and the pulmonary root to the right ventricular outflow tract, after closure of the ventricular septal defect with a patch that ultimately directed flow from the left ventricle to the aorta. This surgical approach has the theoretical advantage of reducing the likelihood of subneopulmonary obstruction, left ventricular outflow obstruction, neoaortic dilatation, and regurgitation and therefore has the potential to minimize the mortality and morbidity related to reintervention and reoperation.
