| 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. |
