    Total surgical correction for truncus arteriosus in infants is recommended between 2 to 3 months of age. Early repair minimizes risks and prevents rapid pulmonary vascular disease development.

    Area of Science:

    • Cardiology
    • Pediatric Surgery
    • Congenital Heart Disease

    Background:

    • Truncus arteriosus is a complex congenital heart defect requiring surgical intervention.
    • Early surgical correction is crucial for improving outcomes in affected infants.
    • Pulmonary vascular disease can rapidly progress in infants with truncus arteriosus.

    Purpose of the Study:

    • To evaluate the outcomes of total surgical correction for truncus arteriosus.
    • To determine the optimal timing for surgical intervention in infants with truncus arteriosus.
    • To assess the risks and benefits of early versus delayed surgical repair.

    Main Methods:

    • Retrospective review of 23 patients with truncus arteriosus undergoing total surgical correction between 1979 and 1983.

  • Surgical techniques included circulatory arrest for infants and cardiopulmonary bypass with core cooling for older patients.
  • Postoperative management focused on close monitoring of pulmonary artery pressure and treatment with hyperventilation and vasodilators.

    • Main Results:

    • Overall mortality was low, with two early deaths in neonates with severe preoperative conditions.
    • One late death occurred, likely due to a preventable pulmonary hypertensive crisis.
    • Infants undergoing repair at 2-3 months of age experienced favorable outcomes.

    Conclusions:

    • Total surgical correction for truncus arteriosus during infancy, ideally at 2-3 months, offers a low-risk approach.
    • Early intervention prevents the rapid development of pulmonary vascular disease.
    • Timely surgical repair significantly improves survival rates and long-term prognosis for patients with truncus arteriosus.
