    Area of Science:

    • Cardiovascular Surgery
    • Cardiac Anesthesia
    • Cardioplegia

    Background:

    • Myocardial protection is critical during cardiac surgery.
    • Traditional cardioplegia methods can be complex.
    • Need for simplified and effective myocardial protection strategies.

    Purpose of the Study:

    • To describe a novel technique for myocardial protection using cold blood cardioplegia.
    • To evaluate the efficacy and safety of this technique in cardiac surgical procedures.
    • To present a simplified approach to myocardial preservation during cardiac surgery.

    Main Methods:

    • Utilized a cardioplegic solution of cold blood (10°C) with potassium (30 mEq/L).
    • Employed a disposable cooling coil, eliminating the need for a separate coronary perfusion pump head.

  • Used the aortic perfusion cannula for left ventricular venting and air removal.

    • Main Results:

    • Successfully applied the technique in 125 consecutive coronary revascularization procedures.
    • Successfully applied the technique in 73 consecutive pediatric cardiac surgical procedures.
    • Reported excellent clinical outcomes in all treated patients.

    Conclusions:

    • The described cold blood cardioplegia technique offers an effective and simplified method for myocardial protection.
    • This approach is suitable for both adult coronary revascularization and pediatric cardiac surgery.
    • The technique demonstrates excellent results and potential for widespread adoption in cardiac surgery.
