    Area of Science:

    • Cardiovascular Surgery
    • Cardiothoracic Anesthesia
    • Medical Device Innovation

    Background:

    • Hypothermic coronary perfusion is crucial for extending safe cardiac arrest durations.
    • Current methods offer myocardial protection but may have limitations.
    • Achieving profound myocardial hypothermia is key for extended cardiac procedures.

    Purpose of the Study:

    • To describe an innovative method for profound myocardial hypothermia.
    • To demonstrate selective deep hypothermic coronary perfusion without a separate pump head.
    • To enhance myocardial protection during cardiac surgery.

    Main Methods:

    • Utilized a cooling coil for selective deep hypothermic coronary perfusion.
    • Achieved profound myocardial hypothermia.
    • Eliminated the need for a separate pump head in the perfusion system.

    Main Results:

    • Successfully induced profound myocardial hypothermia.
    • Demonstrated the efficacy of the cooling coil method.
    • Extended the safe duration of anoxic arrest through selective hypothermic perfusion.

    Conclusions:

    • Selective deep hypothermic coronary perfusion using a cooling coil is an effective method.
    • This technique provides extended myocardial protection.
    • The described method offers a simplified approach to profound hypothermia in cardiac surgery.
