Abstract
- Transluminal balloon valvuloplasty was performed in the treatment of congenital pulmonic valvular stenosis in5 children, aged 4 months to 15 years. the right ventricular outflow tract pressure gradient decreaed significantly immediately after the procedure from 87.18±56mmHg to 29.62±26.48 mmHg (p<.001). Technical success rate was 98%(54/55 patients) and failed case(1 patient) was due to severe fibrous thickening of valve. Complication occurred in one case, that is tricuspid regurgitation (Grade II) due to suspected rupture of chordaetendinae. The degree of pulmonary conus dilatation was closely related with age than the pressure gradient.
