The Nikaidoh procedure for complex transposition of the great arteries: short-term follow-up

BackgroundThe surgical treatment for complex forms ofd-transposition of the great arteries associated with ventricular septal defect and left ventricular outflow tract obstruction remains controversial. In this study, we describe the classical surgical options – namely, the Rastelli procedure and the “réparation à l’étage ventriculaire” – and present our experience with the modified Nikaidoh procedure with early and short-term follow-up results.MethodsBetween 2007 and 2014, four patients withd-transposition of the great arteries associated with ventricular septal defect and left ventricular outflow tract obstruction underwent surgical repair at our institution by means of a modified Nikaidoh procedure.ResultsWith a mean follow-up of 4.5 years, survival was 100%, and none of the patients required re-intervention or mechanical circulatory support. There was no recurrence of left ventricular outflow tract obstruction and no aortic valve regurgitation classified as more than mild. Left ventricular function was preserved.ConclusionsAortic translocation with the modified Nikaidoh procedure is a safe and effective surgical treatment for certain complex forms of transposition of the great arteries, particularly those associated with ventricular septal defect and left ventricular outflow tract obstruction. It is associated with less need for re-intervention and better morbidity and mortality results in the short- and mid-term follow-up, when compared with the classical alternatives such as the Rastelli procedure.
