    Repeated cardiac valve replacement surgery, even third or fourth replacements, is becoming more common. This study found that despite increased complexity, repeated valve replacement carries an acceptable operative risk for patients.

    Area of Science:

    • Cardiovascular Surgery
    • Cardiac Valve Disease
    • Medical Device Technology

    Context:

    • Increasing frequency of repeat cardiac valve replacement surgeries.
    • Over two decades of data collection (1970-1984) at Hôpital Foch.
    • Analysis of 2072 implanted prostheses, with 6.4% requiring at least one reoperation.

    Purpose:

    • To evaluate the outcomes and risks associated with multiple cardiac valve reoperations.
    • To assess the technical feasibility and patient survival after repeated valve replacements.
    • To determine the long-term functional status of patients undergoing multiple valve surgeries.

    Summary:

    • 134 out of 2072 valve prostheses required reoperation; 27 (1.3%) underwent three or more replacements in 23 patients.
    • Procedures, primarily median sternotomy, involved simple valve replacement or more complex techniques.

  • Hospital mortality was 13%, with 10% late deaths; 17 survivors showed improved NYHA functional class.

    • Impact:

    • Repeated valve replacement demonstrates an acceptable operative risk.
    • Suggests feasibility of complex cardiac valve reoperations.
    • Highlights the need for careful patient selection and surgical planning for multiple valve replacements.
