Heart failure can make your heart too weak to pump out enough oxygen-rich blood to meet your body's needs. That will leave you tired and short of breath. It may be hard to climb stairs, go to work, or exercise.
One way to get your heart back into a healthy rhythm, and help you get back to your normal routine, is with an implanted left ventricular assist device (LVAD). An LVAD takes over some of the work for your heart.
