Percutaneous balloon pulmonary valvuloplasty.

Z Lababidi, J R Wu

    The American Journal of Cardiology
    |September 1, 1983
    PubMed
    Summary

    Percutaneous balloon pulmonary valvuloplasty effectively treated pulmonary stenosis in pediatric patients. This minimally invasive procedure significantly reduced pressure gradients across the pulmonary valve without impacting cardiac output.

    Area of Science:

    • Cardiology
    • Interventional Cardiology
    • Pediatric Cardiology

    Background:

    • Pulmonary stenosis (PS) is a significant congenital heart defect.
    • Valvular PS requires effective treatment to prevent right ventricular strain.
    • Percutaneous balloon pulmonary valvuloplasty (BPV) is a less invasive option.

    Purpose of the Study:

    • To evaluate the efficacy and safety of BPV in pediatric patients with isolated valvular PS.
    • To assess the impact of BPV on pulmonary valve gradients and right ventricular pressures.

    Main Methods:

    • 18 consecutive patients with valvular PS underwent BPV.
    • Balloon inflations were performed at 80, 100, and 120 psi.
    • Hemodynamic parameters, including peak systolic pulmonary valve gradient (delta P), were measured pre- and post-procedure.

    Main Results:

    • BPV significantly reduced the mean delta P from 81 +/- 31 mm Hg to 23 +/- 11 mm Hg (p < 0.01).
    • Right ventricular peak systolic pressure decreased from 106 +/- 31 to 50 +/- 12 mm Hg (p < 0.01).
    • No pulmonary regurgitation was observed post-BPV.

    Conclusions:

    • BPV is a safe and effective treatment for valvular PS in children and young adults.
    • The procedure leads to significant hemodynamic improvement.
    • BPV may serve as an alternative to surgical intervention for PS.
