Purpose : Balloon valvuloplasty(BVP) is the treatment of choice for valvular pulmonary stenosis (PS). However, this procedure was usually performed in children older than 2 years. The purpose of the present study was to assess the safety and efficacy of BVP in young infants. Methods : Retrospective analysis of the medical records of 25 infants younger than 6 months of age...

Congenital pulmonary valvular stenosis was relieved by percutaneous balloon valvuloplasty during cardiac catheterization on 8 children aged 14 months to 8 years. Before dilatation, the transpulmonary systolic pressure gradients ranged from 33 mmHg to 79 mmHg (Mean:52.00 ± 18.16 mmHg). There were significant reduction in the transpulmonic systolic pressure gradients immediate after balloon dilatation (Mean:17.38±11.16mmHg). In follow up 4 patients, this decreased pressure gradients have...
