A Left Ventricular Assist Device (LVAD) is a mechanical pump that helps the left ventricle—the heart's main pumping chamber—circulate blood throughout the body. It is often used in patients with advanced heart failure, either as a temporary support while waiting for a heart transplant (bridge to transplant) or as a long-term solution (destination therapy) for those who are not transplant candidates. The LVAD is surgically implanted and powered by an external battery pack worn outside the body. While not a cure, it can greatly improve symptoms and quality of life.
