A ventricular assist device (VAD) takes over some or all of the pumping function of the heart. It is implanted either as a bridge-to-transplantation or, as an alternative to transplantation (called destination therapy).
At the core of the HeartWare® Ventricular Assist System is the HVAD® Pump. The pump sits inside your chest and is connected directly to your heart. It pumps blood from the left side of your heart into your aorta (large blood vessel that carries blood from your heart to the rest of your body). The blood exits the pump in a continuous stream much like water out of a garden hose. This continuous flow of
blood is different than the pulsing beat of a normal heart, and as a result you may not be able to feel your pulse. There is no need for concern, this is completely normal.
The HVAD Pump is run by a small external computer, called a controller. The pump and the controller are connected by a small cable (driveline) that passes through the skin on your upper abdomen. The controller runs the pump and also provides text messages and audible alarms to help you manage the operation of the system. The controller is powered by two batteries, or one battery and electricity from a wall or car outlet.
