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.
Types of VADs. Ventricular assist devices are mechanical pumps that take over the function of the damaged ventricle in order to re-establish normal hemodynamics and end-organ blood flow. In addition, VADs unload the native heart allowing it to rest and, in some cases, the heart can recover function.
