[Re-operations on patients with ball valve prostheses].

J Valty, P Bickert, P Maurice

    Archives Des Maladies Du Coeur Et Des Vaisseaux
    |May 1, 1977
    PubMed
    Summary

    Reoperation for ball-valve prostheses occurred in 6.7% of cases, primarily due to displacement. While 71% of survivors had satisfactory results, operative mortality was high, emphasizing the need to prevent reoperations.

    Area of Science:

    • Cardiovascular Surgery
    • Biomaterials Science
    • Clinical Outcomes Research

    Context:

    • Ball-valve prostheses are widely used in cardiac surgery.
    • Reoperation rates and outcomes are critical for long-term patient management.
    • Understanding failure modes is essential for improving prosthetic device longevity.

    Purpose:

    • To analyze the indications, risk factors, and outcomes of reoperations in patients with ball-valve prostheses.
    • To identify key factors contributing to operative mortality and long-term survival.
    • To inform strategies for preventing future reoperations and improving patient care.

    Summary:

    • A study of 989 cases found a 6.7% reoperation rate for ball-valve prostheses.
    • Primary indications included displacement (75.5%), malfunction (10.5%), and associated lesions (14%).
    • Significant risk factors for mortality included prior endocarditis, NYHA Class IV, QRS widening, urgent reoperation, and prolonged extracorporeal circulation.

    Impact:

    • High operative mortality (31.8%) necessitates improved prevention of reoperations.
    • Despite risks, 71% of survivors experienced satisfactory clinical results.
    • Findings guide research towards preventing prosthetic valve failures and reducing reoperation rates.
