Introduction and objective: Balloon aortic valvuloplasty is regarded as a good palliative option for congenital aortic stenosis in children. Our main objective was to review the results of all consecutives balloon aortic valvuloplasties performed in children over a native valve from march 1994 until June 2013, trying to identify those variables associated with need of reintervention during follow-up.Methods: We studied the echocardiographic, clinical and evolutionary features of 51 pediatric patients who underwent a balloon aortic valvuloplasty. Two groups were recognized: neonatal (n = 11) and pediatric (n = 40) patients depending on whether valvuloplasty was performed before or after the first month of life. Median follow-up was 5.8 years (0.5-12,3).Results: There were 37 boys and 14 girls, and 20 patients had some additional cardiac malformation. The average peak to peak hemodynamic gradient fell from 60 ± 18 a 25 ± 13 mmHg.During follow-up, 12 patients needed a second valvuloplasty for reestenosis (23.5%) at 0.61years (0.3-3.2) and 13 others needed surgery (25%) at 1.62 years (0.4-10.9); 2 cases (4%) hadno follow-up. The variables neonatal group, echocardiographic restrictive diastolic pattern,z-score of end-diastolic left ventricle diameter < -2.5, and peak to peak hemodynamic gradient > 60 mmHg were associated with need of surgery during follow-up (p < 0.05). However, wedid not find factors associated with repeated valvuloplasty.Conclusions: Balloon aortic valvuloplasty in children is an effective option for palliative treatment of congenital aortic stenosis. In this study the variables previously described were predictors of the need of surgery.
