Early outcome for the primary arterial switch operation beyond the age of 3 weeks.
The arterial switch operation (ASO) for neonates is the standard management for transposition of the great arteries (TGA) with an intact ventricular septum (IVS). Patients presenting for late ASO are at risk due to the possibility of left ventricle (LV) involution. This study aimed to assess the early postoperative course and outcome for children with TGA/IVS and still conditioned LV presenting for late primary ASO. A retrospective study of all TGA/IVS patients who underwent a primary ASO between March 2002 and March 2008 was conducted. The cases were divided into two groups. Group A included all the cases of early ASO repaired before the age of 3 weeks, whereas group B included all the preslected cases of late ASO repaired after the age of 3 weeks. The demographics, intensive care unit (ICU) parameters, complications, and short-term outcomes of the two groups were compared. The study enrolled of 91 patients: 64 patients (70%) in group A and 27 patients (30%) in group B. The mean age was 11 +/- 4 days in group A and 37 +/- 17 days in group B (P < 0.001). The two groups showed no significant statistical differences in ICU parameters, complications, or mortality. For patients with TGA/IVS, ASO still can be tolerated beyond the first month of life in selected cases. Provided the LV still is conditioned, age should not be a limitation for ASO.
