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.
Heart passages open vertically (atrium and ventricle) and the heart is divided into side-by-side pumps serving two blood circuits: 1  Pulmonary circuit - receives blood returning to the heart from the body and sends it through the lungs for oxygenation.  Systemic circuit - supplies the entire body with oxygenated blood.
