  • Mechanical heart pump gives a young man back his life ...

    2021-6-15 · LVAD adds “horsepower” back to the heart. The LVAD acts as a mechanical pump when the heart is unable to pump blood effectively on its own. It’s attached to the heart and then connected via wire to a battery-operated controller worn outside of the body. Dr. Kiel uses an analogy when explaining the LVAD to his patients.
