    Area of Science:

    • Cardiovascular Surgery
    • Cardiac Valve Repair and Replacement
    • Thoracic Surgery

    Background:

    • Double valve replacement surgery for aortic and mitral positions is associated with high morbidity and mortality.
    • Current surgical techniques include ischemic arrest or coronary perfusion, each with limitations.

    Purpose of the Study:

    • To describe a new surgical technique for double valve replacement aimed at reducing operative mortality.
    • To evaluate the efficacy and safety of this novel approach in patients undergoing aortic and mitral valve replacement.

    Main Methods:

    • A hybrid technique involving ischemic arrest for anterior mitral and aortic valve replacement.
    • Subsequent repair of the posterior mitral valve and left atrium during native ostial myocardial perfusion.

  • Application of the technique in a cohort of 33 patients over a 4-year period.

    • Main Results:

    • The novel technique was employed in 33 patients.
    • A single operative death was recorded in the patient cohort.
    • This approach demonstrated a significant reduction in the observed mortality rate.

    Conclusions:

    • The described surgical method offers a promising alternative for double valve replacement.
    • This technique effectively reduces operative mortality and morbidity in complex cardiac valve procedures.
    • Further research may validate this approach as a new standard of care for aortic and mitral valve replacement.
