Double-root transfer and the half-turned truncal switch

Abstract

Transposition of great arteries (TGA) or double-outlet right ventricle (DORV) with ventricular septal defect (VSD) and pulmonary stenosis (PS) is a complex congenital cardiac malformation, which can be treated by both univentricular and biventricular pathways. Biventricular repair includes Rastelli operation, reparation a l'etage ventriculaire (REV), pulmonary root translocation, and Nikaidoh procedures. Double-root translocation (DRT) technique and half-turned truncal switch technique (HTTS) are being considered as useful alternatives. In this review, we will see in detail about DRT and HTTS.

Keywords: Double-root translocation; Half-turned truncal switch; Nikaidoh.

Operative steps in DRT. a Anatomy assessed: anteroposterior relationship of the great arteries with the aorta in front. b The aorta transected with explantation of single or both coronary button. c Dissection of pulmonary root and performance of Lecompte maneuver. d VSD closure through RVOT. e The aorta, anastomosed posterior into the LVOT with reimplantation of coronary button/s (one/both). f The pulmonary artery is then anastomosed onto the RVOT and anteriorly augmented with pericardium
