We describe a surgical technique for a half-turned truncal switch operation in a 5-year-old child with dextro-transposition of the great arteries (D-TGA), a ventricular septal defect, a left ventricular outflow tract obstruction and a complex coronary pattern. The benefit of the half-turned truncal switch is the creation of haemodynamically superior biventricular outflow tracts and the maximal use of an autologous pulmonary valve in the right ventricular outflow tract, thereby avoiding the right ventricular-pulmonary artery conduit.
Keywords: Left ventricular outflow tract obstruction; Transposition of the great arteries; Truncal root translocation; Ventricular septal defect.
