Favorable long-term outcomes in hospital survivors of a neonatal arterial switch operation.

ABSTRACT:

Objectives

To assess long-term survival and reoperation-free survival after the arterial switch operation (ASO) and analyze the outcomes of reoperations after hospital discharge.

Methods

This was a single-institution retrospective study of 476 hospital survivors of ASO since August 1982. Preoperative diagnoses included 286 transpositions of the great arteries with intact septum, 143 transpositions with ventricular septal defect, and 47 double outlet right ventricles. There were 236 neonatal ASOs, 30 aortic arch repairs, 22 concomitant left ventricular outflow tract obstruction reliefs, 16 preoperative mild pulmonary regurgitations, and 13 intramural coronary arteries.

Results

During a median follow-up of 21.1 years (range, 0.1-39.2 years), 25 late deaths (5.3%) and 91
