The heart has two stages, in the first stage the left and right Atria contract at the same time pumping blood through the left and right ventricle. In the second stage the ventricles contract together to push blood out of the heart.

An artificial heart provides an extra ventricle to help to pump blood around your body that is called ventricular assist device. A ventricular assist device is made from metal and plastic, and has a small pumping chamber made by a special material that stops blood clots forming.

The “VAD” is connected in many ways, it depends on which side of the heart needs support, your right or left.

If the heart needs support on both sides of your heart, it is attached in both of the above ways.
