Also known as heart pump. A ventricular assist device (VAD) is a mechanical pump that supports heart function and blood flow in people who have weakened hearts. These devices can support the function of the left, right, or both heart ventricles. Ventricles are the lower chambers of your heart.
The left ventricle is the large, muscular chamber of the heart that pumps blood out to the body. A left ventricular assist device (LVAD) is a battery-operated, mechanical pump-type device that's surgically implanted. It helps maintain the pumping ability of a heart that can't effectively work on its own.
