    Area of Science:

    • Biomedical Engineering
    • Cardiovascular Surgery
    • Medical Device Technology

    Background:

    • Acute cardiac conditions necessitate temporary circulatory support for diagnosis and prognosis.
    • Chronic heart failure requires long-term solutions, including ventricular support or replacement.
    • Current pneumatic assist devices have limitations, driving the need for improved technologies.

    Purpose of the Study:

    • To explore the evolving landscape of cardiac assist and replacement devices.
    • To evaluate the potential roles of different device types in cardiac surgery.
    • To project the future impact of advanced artificial heart technologies.

    Main Methods:

    • Review of current and emerging cardiac assist and replacement technologies.
    • Analysis of the clinical applications for extracorporeal and intrathoracic devices.
    • Discussion of the advancements in electrically driven artificial hearts.

    Main Results:

    • Extracorporeal assist devices are crucial for acute cardiac situations.
    • Intrathoracic paraventricular assist devices offer temporary or permanent ventricular support.
    • Electrically driven artificial hearts demonstrate long-term viability in animal models.

    Conclusions:

    • A range of cardiac assist and replacement devices will be integral to cardiac surgery.
    • Pneumatic ventricles will see increased use, but electrically driven systems represent the future.
    • Electrically driven artificial hearts are poised to become the standard of care within the next decade.
