Double-outlet right ventricle. Surgical results, 1970-1980.

J P Judson, G K Danielson, F J Puga

    The Journal of Thoracic and Cardiovascular Surgery

    Summary

    Surgical repair of double-outlet right ventricle (DORV) shows decreasing early mortality but significant late mortality, primarily due to arrhythmias. Further research is needed to address long-term complications in DORV patients.

    Area of Science:

    • Cardiovascular Surgery
    • Pediatric Cardiology
    • Congenital Heart Disease

    Background:

    • Double-outlet right ventricle (DORV) is a complex congenital heart defect.
    • Surgical repair outcomes for DORV have evolved over time.
    • Long-term survival and complications after DORV repair require ongoing evaluation.

    Purpose of the Study:

    • To analyze the early and late outcomes of surgical repair for classic double-outlet right ventricle (DORV).
    • To identify risk factors associated with mortality after DORV repair.
    • To assess the long-term functional status and causes of death in DORV survivors.

    Main Methods:

    • Retrospective review of 62 consecutive patients undergoing DORV repair between 1970 and 1980.
    • Exclusion of patients with specific complex cardiac anomalies.

  • Analysis of early mortality, late mortality, and functional status of survivors.

    • Main Results:

    • Overall early mortality was 15%, with higher rates in patients without pulmonary stenosis (25%).
    • Mortality risk was significantly related to the patient's age at operation.
    • Late mortality among survivors was 21%, with 91% attributed to arrhythmia.

    Conclusions:

    • While operative mortality for DORV repair has decreased, late mortality remains a significant concern.
    • Arrhythmia is a major cause of late death in DORV repair survivors.
    • Further investigation into the management and prevention of late arrhythmias is crucial for improving long-term outcomes in DORV patients.
