Abstract

Objectives:The aim of this article is to report a 16-year experience with percutaneous balloon aortic valvuloplasty (BAVP) in newborns and young infants up to 3 months of age in a tertiary care cardiac reference center in a developing country and to determine its value in postponing open heart surgery. Background:Congenital aortic stenosis (AS) is a potentially life threatening disorder. BAVP and surgical procedures have similar short and medium-term efficacy. Methods:Thirty-one consecutive newborns and young infants with critical AS underwent BAVP in our department from 1991 to 2007. Mean patient age at time of the procedure was 22 days (range 2-92 days) and mean weight was 3,310 g (1,840-4,400 g). Results:There was a significant reduction in mean Doppler-derived peak gradient across the aortic valve immediately after the procedure (75.1 ± 22 versus 32.2 ± 13.02, P <0.001), and this finding was maintained throughout follow-up. Since 2003, when the carotid approach became routine practice, no major vascular complications were observed. Mean time of follow-up was 81 months (5 days-196 months) with only two deaths (7.4%). Only 24% patients required surgical reintervention on the aortic valve during follow-up. Survival free from aortic valve surgery was 80% at 24 months, 66% at 63 months, and 50% at 80 months. Conclusion:Percutaneous intervention for relief of critical aortic stenosis in newborns in a tertiary center of a developing country is safe and has excellent short and long-term results comparable to other centers throughout the world.
