OBJECTIVE
The aim of this study was to evaluate the efficacy and safety of the Doty surgical approach in pediatric patients with congenital supravalvular aortic stenosis (SVAS) by examining early and mid-term outcomes.

METHODS
Surgical repair using the Doty technique was performed in a total of 10 pediatric patients with SVAS between January 2005 and July 2015 at this clinic. These patients were evaluated retrospectively. Demographic characteristics, echocardiographic findings, and clinical outcomes were analyzed.

RESULTS
The mean patient age was 4.8±3.9 years. Williams-Beuren syndrome was diagnosed in 4 of the patients. Early mortality was observed in 1 patient with diffuse SVAS. At the final follow-up (mean follow-up: 3.7±1.2 years; range: 6-61 months), echocardiograms revealed a mean pressure gradient of 14±4.2 mmHg. Two patients displayed minimal aortic insufficiency during the follow-up period. No reoperation or reintervention was required.

CONCLUSION
The Doty technique is an anatomically and technically effective surgical approach to treating SVAS.
