The Left Ventricular Assist Device (LVAD) is now an FDA-approved practical remedy for people with failing hearts. This device typically bypasses the left ventricle and pumps blood directly into the aorta, from which it enters the systematic circulation. More recent systems also assist the right ventricle as well. The device is either implanted entirely within the body with power lines and an air vent brought outside the body through the skin, or their pumps are located outside the body and connected to the heart and large blood vessels with tubes passing through the chest. This technology will definitely have greater impact on society than the artificial heart. The only and very important issue hindering its wide application is cost.
