Mechanical cardiac support with the HVADTM system

The HVADTM is surgically implanted in your chest and is connected directly to your heart, at the bottom of the left ventricle, where it draws oxygenated blood through the pump and pushes it into your aorta. From the aorta, the blood flows around your whole body.

Illustration of the HVAD system with numbered parts
  1. The HVADTM Pump is implanted in your heart at the bottom of the left ventricle.
  2. A driveline cable transfers power and information between the pump and the controller. Part of the driveline exits the body through a small incision in the skin.
  3. The wearable controller monitors the pump, sending you information to tell you about how the system is working. Batteries, or an electrical (A/C) cable, are connected to the controller and continuously power the pump. The driveline cable must be attached to the controller and two power sources at all times.
  4. A wearable pack holds the external equipment, allowing the patient to move about freely when A/C power is not required.

Living with the HVADTM system

Part of living with the HVADTM system is looking after all of the system components that come with the pump.

The control unit is a small computer that monitors the HVADTM pump. It displays text messages and emits audible alarms to help you manage the system.

The external components of the HVADTM system

The HVADTM system alleviates the symptoms of heart failure, enabling patients to feel stronger and return to a more active lifestyle and better quality of life.1,2

The control unit is powered by two batteries, or by electricity from the mains or a car socket. Two fully charged batteries can run the control unit for 8 to 12 hours on the move. The HVADTM system is supplied with several batteries, a battery charger and multiple power adapters.

The control unit and batteries together weigh less than 1.6 kg. Both can be easily stowed together in the shoulder or hip pouch provided.

Note

Consult your GP or cardiologist if you have signs of heart failure or if your symptoms worsen.

Your doctor can provide you with comprehensive information about further treatment and hospitals in which VAD therapy is offered — should this be recommended in your case.
