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 occurs when the heart is too weak to pump all the blood it receives and blood begins to back up. Blood can back up into the lungs and into the lower parts of the body. This can cause trouble breathing, cough, and swelling of 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 for permanent treatment in people who:
If you are planning to have VAD implantation, your doctor will review a list of possible complications, which may include:
Factors that may increase the risk of complications include:
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 discuss these risks with your doctor before the surgery.
If you need a VAD, it is because your heart is failing. Most likely, you will be on a list to receive a heart transplant. You may already be in the hospital. Your doctor will do many tests, including:
Leading up to the procedure, your doctor will instruct you to:
General anesthesia will be used. It will block any pain and keep you asleep through the surgery.
This procedure involves open heart surgery. An incision will be made down the length of your breast bone. The breast bone will then be split and separated. You will be placed on a heart-lung machine. This machine will take the place of your heart and lungs during the surgery. The VAD will be placed into a pocket on the inside of the abdominal wall. Tubes will be sewn to your heart. Tubes may also be sewn to your aorta, depending on the type of device.
You will be in the intensive care unit (ICU) after the procedure. You will be connected to many tubes. The medical staff will monitor you.
About 4-8 hours
You will have pain from the surgery. Ask your doctor about medications to help with the pain.
When you return home, do the following to help ensure a smooth recovery:
After you leave the hospital, contact your doctor if any of the following occurs:
In case of an emergency, call for emergency medical services right away.
