J H Kay, P Zubiate, M A Mendez

    American Heart Journal
    |August 1, 1978
    PubMed
    Summary

    Mitral valve repair offers superior long-term outcomes compared to valve replacement, with fewer complications like emboli. This study emphasizes repair as the preferred surgical option for mitral insufficiency.

    Area of Science:

    • Cardiovascular Surgery
    • Cardiac Valve Repair
    • Mitral Valve Disease

    Background:

    • Skepticism has historically surrounded the long-term efficacy of open heart surgery for pure mitral insufficiency.
    • Mitral valve repair versus replacement outcomes remain a critical area of surgical research.

    Purpose of the Study:

    • To evaluate the long-term results of mitral valve repair for pure mitral insufficiency.
    • To compare the efficacy of mitral valve repair with valve replacement using prosthetic valves.

    Main Methods:

    • Retrospective analysis of 145 patients undergoing isolated mitral valve repair.
    • Analysis of 55 patients undergoing mitral valve repair combined with myocardial revascularization.
    • Comparison of outcomes with historical data on Starr-Edwards and Hancock valve replacements.

    Main Results:

    • Mitral valve repair demonstrated superior outcomes compared to replacement with mechanical (Starr-Edwards) and bioprosthetic (Hancock) valves.
    • Fewer embolic events were observed in patients who underwent mitral valve repair.
    • Successful long-term results were achieved in patients with repaired mitral valves.

    Conclusions:

    • Mitral valve repair is a safe and effective procedure for mitral insufficiency, offering better results than valve replacement.
    • The study advocates for a conservative approach, prioritizing valve repair over replacement in eligible patients.
    • Mitral valve repair should be considered the preferred surgical strategy for patients with mitral insufficiency.
