Abstract

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 maintained with mean late residual pressure gradi- ents of 13.75± 10.52 mmHg by Doppler echocardiography. In conclusion, balloon pulmonary valvuloplasty appears to provide good relief of pulmonary valvular stenosis and may be considered the treatment of choice in congenital pulmonary valvular stenosis.
