    This study reports the first balloon pulmonary valvuloplasty in the country for a 12-year-old girl with severe pulmonary valve stenosis. The procedure significantly reduced the transvalvular gradient, offering a promising treatment option.

    Area of Science:

    • Cardiology
    • Interventional Cardiology
    • Pediatric Cardiology

    Background:

    • Congenital pulmonary valve stenosis is a significant cause of right ventricular outflow tract obstruction in children.
    • Traditional surgical interventions carry risks and may require re-intervention.
    • Balloon pulmonary valvuloplasty offers a less invasive alternative.

    Observation:

    • A 12-year-old female presented with severe pulmonary valve stenosis, indicated by a transvalvular gradient of 94 mmHg.
    • The first balloon pulmonary valvuloplasty was successfully performed in the country for this condition.
    • Immediate post-procedure gradient decreased to 20 mmHg.

    Findings:

    • Cardiac catheterization four months post-procedure showed a sustained gradient of 26 mmHg, indicating durable results.

  • The technique, hemodynamic changes, and potential complications were detailed.
  • Literature review supports balloon valvuloplasty as a primary treatment modality.

    • Implications:

    • Balloon pulmonary valvuloplasty is a safe and effective first-line treatment for congenital pulmonary valve stenosis.
    • This procedure can significantly improve hemodynamic status and reduce the need for surgery.
    • Further research and widespread adoption can improve outcomes for pediatric patients with this condition.
