Abstract

Background

Coarctation of the aorta is a congenital narrowing of the upper descending aorta. The approximate incidence is 4% in live-born children with congenital heart disease. This study aimed to describe the surgical outcome and survival of patients undergoing congenital aortic coarctation repair via subclavian flap aortoplasty (group 1) or resection with end-to-end anastomosis (group 2).

Methods

We retrospectively reviewed the clinical outcomes of 105 infants who underwent repair of aortic coarctation between 2000 and December 2012. Fifty patients (group 1) underwent subclavian flap aortoplasty and 55 (group 2) underwent resection with end-to-end anastomosis. Procedure details and early results were collected by retrospective review of hospital and clinic data.

Results

The mean age of patients in group 1 was 6.73 ± 1.1 vs. 6.76 ± 1.2 months in group 2, and the mean weight was 6.01 ± 1.3 vs. 5.9 ± 1.0 kg, respectively. There were no significant differences among the intra- and postoperative variables in the 2 groups. Six patients in group 1 had a peak systolic gradient >20 mm Hg. The recurrence rate in group 1 was 12% vs. 1.8% in group 2 (p < 0.05). Overall mortality was 2.8%. Survival in group 1 was 96% vs. 98.2% in group 2.

Conclusion

Repair of aortic coarctation in infancy by resection with end-to-end anastomosis can be performed with a low mortality rate and a low incidence of recoarctation, and it provides the optimal prognosis for coarctation in infancy.
