A heart assist system implantation is an artificial heart. It is also called a ventricular assist device (VAD). This single-chamber artificial heart works by compressed air or battery power. The device boosts the function of a failing heart ventricle.

Heart failure happens when the heart is too weak to pump the blood the body needs. Blood starts to back up. It backs up into the lungs and lower parts of the body. This can cause breathing problems, coughing, as well as swelling in the legs and ankles.
Getting a VAD is a way to improve the heart's ability to pump without having a heart transplant. A VAD is sometimes referred to as a bridge to transplant, since it can be used while a person is waiting for a heart transplant. This device can also be used as a permanent treatment in people who:
Problems from the procedure are rare, but all procedures have some risk. Your doctor will review possible problems such as:
Your chances for problems are higher for:
Also, if you have a small stature, you may not be able to get a VAD due to the size of the device.
Be sure to talk about these risks with your doctor before the surgery.
If you need a VAD, it's because your heart's failing. Most likely, you will be on a list to receive a heart transplant. You may already be in the hospital. You may also have:
Leading up to the procedure:
General anesthesia will be used. You will be asleep.
This is an open heart surgery. A cut will be made down the length of the breastbone. The breastbone will then be split open. A machine will replace heart and lung function during the procedure. The VAD will be placed into a pocket on the inside of the belly wall. Tubes will be sewn to the heart. Tubes may also be sewn to the aorta. This will depend on the type of device needed.
You will be in the intensive care unit (ICU). You will be connected to many tubes. The healthcare staff will watch you.
About 4-8 hours
Anesthesia will prevent pain during surgery. Medicines will help ease pain after.
