    Area of Science:

    • Cardiovascular Surgery
    • Thoracic Surgery
    • Organ Transplantation

    Background:

    • Organ preservation is critical for successful transplantation.
    • Current preservation times limit the viability of donor organs, particularly the heart and lungs.
    • Robicsek's original autoperfusing preparation provided a foundation for improved techniques.

    Purpose of the Study:

    • To evaluate a modified autoperfusing heart-lung preparation system.
    • To assess the structural integrity of canine lungs and hearts after prolonged preservation.
    • To determine the potential of this modified system for extending organ preservation limits.

    Main Methods:

    • A modified Robicsek's autoperfusing heart-lung preparation was utilized.
    • Canine lungs and hearts were preserved using the modified system.

  • Structural integrity of preserved organs was assessed over time.

    • Main Results:

    • Normal lung structure was maintained for up to 8 hours.
    • Normal heart structure was maintained for up to 12 hours.
    • The modified preparation demonstrated effective organ preservation.

    Conclusions:

    • The modified autoperfusing heart-lung preparation significantly extends organ preservation times.
    • This technique shows promise for improving outcomes in heart and heart-lung transplantation.
    • Extended preservation could increase organ availability and reduce transplant waiting times.
