    Insights

    Pulmonary vascular disease does not impact infant mortality from large ventricular septal defect repair. Optimal surgical timing depends on patient age, pulmonary vascular resistance, and pressure for improved long-term outcomes.

    Area of Science:

    • Cardiology
    • Pediatric Surgery
    • Pulmonology

    Background:

    • Ventricular septal defects (VSDs) are common congenital heart defects.
    • Pulmonary vascular disease (PVD) can complicate VSD management.
    • Surgical closure is a primary treatment for large VSDs.

    Purpose of the Study:

    • To evaluate the impact of PVD on surgical outcomes for large VSDs.
    • To identify factors influencing late results after VSD repair.
    • To determine optimal timing for surgical intervention.

    Main Methods:

    • Review of cases involving surgical closure of large VSDs.
    • Analysis of hospital mortality and late outcomes.
    • Application of probability of event analysis.

    Main Results:

    • Preoperative PVD did not affect in-hospital mortality in infants.
    • Late results were significantly influenced by age at operation, preoperative pulmonary vascular resistance, and pulmonary artery pressure.
    • Probability of event analysis identified optimal age ranges for repair.

    Conclusions:

    • Surgical closure of large VSDs is feasible in infants with PVD without increased immediate mortality.
    • Long-term success is optimized by considering age, pulmonary hemodynamics, and utilizing probability of event analysis for timing.
    • Individualized surgical timing is crucial for favorable late outcomes in VSD repair.
