Interrupted aortic arch can be associated with transposition of the great arteries with ventricular septal defect and with the Taussig-Bing anomaly. This usually results in a marked disparity between the hypoplastic ascending aorta and the dilated main pulmonary artery. Currently, standard arterial switch and arch repair is a widely applied approach to the surgical management of these lesions. Though the morphology of the great vessels in these lesions does not preclude this approach, the great-vessel mismatch can result in difficulties at and beyond the proximal neo-aortic to ascending aortic suture line that cause excessive bleeding, obstruction, tension, distortion, and the need of patch augmentation of the ascending aorta or arch with nonviable material. We present an alternative surgical approach used in 2 patients, 1 with Taussig-Bing anomaly and interrupted aortic arch and the other with transposition of the great arteries, ventricular septal defect, and interrupted aortic arch, that greatly simplifies the reconstruction of the neo-aorta and repair of the interrupted arch and avoids these potential hazards.
