    Abstract:
    Moderate to severe aortic stenosis in children requires an initial procedure to improve the stenosis and often additional procedures for recurrent stenosis or aortic insufficiency before adulthood. The purpose of this study was to evaluate children who underwent balloon valvuloplasty and were followed with a specific management plan. Twenty-two children with aortic stenosis underwent balloon valvuloplasty and were followed on a regular basis. Repeat valvuloplasty was performed if indicated. The initial gradient was reduced from 63 +/- 9 mmHg to 28 +/- 8 mmHg (P < 0.001). There were no deaths and only one major complication, which had no sequelae. Average follow-up was 61 +/- 23 months. Three patients required valve replacement 39-76 months after valvuloplasty for progressive insufficiency. Seven patients underwent successful repeat valvuloplasty. The overall probability of survival without surgical intervention was 75% at 100 months. Balloon valvuloplasty is an effective intermediate palliation for aortic stenosis and is an acceptable alternative to surgical valvotomy. Repeat valvuloplasty is successful without additional risk. In a subgroup of patients, aortic insufficiency is progressive and will require surgical intervention.
