WebThe LVAD keeps the heart pumping until a donor heart organ is available. Destination therapy. The LVAD is used as a permanent implant to lessen symptoms for people who can't have other treatments, such as transplantation. How does an LVAD work? An LVAD is a battery-operated pump implanted inside the heart’s left ventricle or attached to it. A ventricular assist device (VAD) — also known as a mechanical circulatory support device — is a device that helps pump blood from the lower chambers of your heart (ventricles) to the rest of your body.
