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 heart and blood vessels (arteries, capillaries, and veins) are called the cardiovascular system. The cardiovascular system carries blood throughout the body. The heart pumps blood through blood vessels called arteries and then through smaller blood vessels called capillaries to each organ and tissue in the body.
