    A novel technique for apex cannulation without extracorporeal circulation was developed, simplifying left ventricle assist device implantation. This method minimizes bleeding and cardiac trauma, making it ideal for research and clinical applications.

    Area of Science:

    • Cardiovascular Surgery
    • Medical Devices
    • Surgical Techniques

    Background:

    • Left ventricle assist device (LVAD) implantation often involves complex procedures.
    • Minimizing complications during LVAD surgery is crucial for patient outcomes.
    • Extracorporeal circulation can increase surgical risks and costs.

    Purpose of the Study:

    • To present a simple, fast, and reliable technique for apex cannulation.
    • To demonstrate the feasibility of apex cannulation without extracorporeal circulation.
    • To reduce complications associated with traditional LVAD implantation methods.

    Main Methods:

    • Over 30 left ventricle assist device implants were performed in calves.
    • A novel technique for apex cannulation was developed and refined.

  • The procedure was conducted without the use of extracorporeal circulation.

    • Main Results:

    • The technique proved to be simple, fast, and highly reliable.
    • Minimal bleeding and reduced risk of ventricular fibrillation, air emboli, muscle flap, and cardiac trauma were observed.
    • No special tools or expensive apparatus were required.

    Conclusions:

    • The described apex cannulation technique is unique and highly applicable to investigative laboratories.
    • The method is practical for immediate clinical application.
    • This approach can avoid potential complications associated with conventional cannula insertion.
