Balloon valvuloplasty as a treatment of congenital aortic stenosis in children and adolescents

摘要

Introduction. Balloon valvuloplasty (BVP) is one of the primary therapies for congenital aortic stenosis in children and adolescents. The aim of this interventional procedure is to gain time before possible surgical therapy (aortic valve replacement) until adulthood. Objective. The aim of this study was to evaluate the efficacy, safety and mid-term results of transcatheter BVP in children and adolescent in our Center. Methods. From 2004 to 2011, 50 patients, aged 18 days to 18 years (mean 6.3 years) underwent BVP. Retrospective analysis of the echocardiographic and hemodynamic parameters were performed before and after procedure, especially peak pressure gradient (PG) across the aortic valve, semiquantification of the aortic regurgitation (AR) after the BVP as well as the left ventricle dimensions and functions. Results. The mean peak PG in the whole group decreased from 74.80±27.72 mm Hg to 27.86±13.04 mm Hg (p
