Reoperation in congenital aortic stenosis.

R G Johnson, G R Williams, J D Razook

    The Annals of Thoracic Surgery
    |August 1, 1985
    PubMed
    Summary

    Critical aortic stenosis in children requires ongoing management. Repeat operations improve long-term survival, especially for subvalvular lesions, emphasizing the need for vigilant follow-up and intervention.

    Area of Science:

    • Pediatric Cardiology
    • Cardiac Surgery
    • Congenital Heart Disease

    Background:

    • Critical aortic stenosis presents a significant challenge in pediatric cardiac care.
    • Management strategies evolve over time, impacting long-term outcomes.

    Purpose of the Study:

    • To evaluate the long-term outcomes and survival rates of pediatric patients undergoing surgical repair for critical aortic stenosis.
    • To assess the impact of reoperations on survival and functional status.

    Main Methods:

    • Retrospective analysis of 81 pediatric patients (3 days to 20 years) undergoing initial aortic stenosis surgery over 22 years.
    • Long-term follow-up of survivors, including those requiring one or more reoperations.
    • Actuarial survival analysis and comparison of outcomes based on stenosis type (valvular vs. subvalvular).

    Main Results:

    • Perioperative mortality was 3.7% for initial operations and 18.2% for reoperations.
    • Actuarial reoperation-free survival was 56.7% at 10 years; overall survival was 88.6% at 10 years.
    • Patients with valvular stenosis had significantly poorer survival compared to those with subvalvular lesions (p = 0.03).

    Conclusions:

    • Children with critical aortic stenosis benefit from continuous monitoring, including recatheterization and timely reoperations.
    • Aggressive management with reoperation is crucial for optimizing long-term survival and functional outcomes in this population.
    • Distinguishing between valvular and subvalvular stenosis is important for prognostic assessment.
