Arterial switch and modified Konno procedure with detachment of the aortic root for transposition of the great arteries and left ventricular outflow tract obstruction.

The arterial switch operation for the transposition of the great arteries accompanied by a ventricular septal defect and posterior malalignment of the outlet septum is a surgical challenge. We describe a new surgical technique in 2 patients having this pathology. The surgical technique consists of the arterial switch operation and a modified Konno procedure through partial detachment of the semilunar valve of the right ventricle as in the Ross procedure.
