Aortic translocation procedure: Early outcomes from a single center.

BACKGROUND/AIM: The data on the Nikaidoh procedure is limited in the literature. This study presents our experiential findings with aortic translocation (Nikaidoh) procedure and its modifications. METHODS: We retrospectively reviewed the data of all the patients who underwent aortic translocation in our institution. RESULTS: Between September 2014 and November 2018, eight patients underwent aortic translocation surgery. The median age was 3.2 years (14 months and 9 years). The diagnosis was transposition of the great arteries (TGA), ventricular septal defect (VSD), and left ventricular outflow tract obstruction (LVOTO) in five patients (63%); double-outlet right ventricle (DORV), VSD, and LVOTO in two patients (25%) and DORV and remote VSD in one patient (12%). Additionally, two patients had tricuspid straddling. In terms of surgical procedures, six patients underwent standard Nikaidoh procedures, while one patient underwent double root translocation and one patient underwent a half-turned truncal switch operation. Hospital mortality was recorded for one patient (12.5%). Median intensive care and hospital stay duration was 3 days (interquartile range [IQR]: 2-5 days) and 11 days (IQR: 8-17 days). Median follow-up duration was 10 months (IQR: 10-24 months). One of the patients, who underwent standard Nikaidoh procedure, died in the late follow-up. CONCLUSIONS: Aortic translocation procedure is an option for TGA, VSD, and LVOTO patients with a distal VSD or tricuspid straddling and DORV patients with a small VSD. Avoiding the use of a conduit through modifications, such as double root translocation and half-turned truncal switch operation, may decrease the risk of long-term recurrent interventions.
