To explore the clinical effects of percutaneous balloon pulmonary valvuloplasty (PBPV) on the treatment of congenital pulmonary valvular stenosis (PS) in children.
From March 1996 to December 2006, 16 children were diagnosed as pulmonary valvular stenosis in the First People's Hospital of Zhaoqing and First People's Hospital of Foshan. They were performed by percutaneous balloon pulmonary valvuloplasty using one balloon (n=9) or dual balloon (n=7) according to their age and degrees of pulmonary valvular stenosis.Informed consent was obtained from all participants.
There were remarkable declines in post-ballooning residual transvalvular pressure gradient (ΔP) after the percutaneous balloon pulmonary valvuloplasty on 16 children. There had significant difference between post-ballooning and pre-ballooning in transvalvular pressure gradient (t=4.13, P<0.05).
Percutaneous balloon pulmonary valvuloplasty operation is simple and safe, which should be the first choice for children with pulmonary valvular stenosis.
