    Summary

    A new method allows direct intraoperative observation of mitral valve function after surgery. This technique aids in assessing the success of mitral valve repair and commissurotomy procedures.

    Area of Science:

    • Cardiovascular Surgery
    • Cardiac Surgery Techniques
    • Mitral Valve Repair

    Background:

    • Preoperative assessment of mitral valve function is typically accurate.
    • There is a need for intraoperative methods to evaluate dynamic mitral valve function, especially after procedures like open commissurotomy or valvuloplasty.

    Purpose of the Study:

    • To develop a safe intraoperative method for direct observation of the mitral valve closure mechanism.
    • To assess the efficacy of mitral valve repair (annuloplasty) during surgery.

    Main Methods:

    • Utilized direct observation of the mitral valve closure mechanism.
    • Employed a left ventricular vent.
    • Incorporated a slight modification to the standard cardiopulmonary bypass circuit.
    • Applied the method in over 250 mitral annuloplasty cases.

    Main Results:

    • Developed a safe and effective method for direct intraoperative visualization of mitral valve dynamics.
    • The technique allows for real-time assessment of mitral valve function post-intervention.

    Conclusions:

    • The described method provides direct intraoperative insight into mitral valve function.
    • This technique is valuable for evaluating the success of mitral valve repair and commissurotomy.
