LVAD at Piedmont Augusta
Piedmont Augusta's Advanced Heart Failure Center
1350 Walton Way
Augusta, GA 30901-2629
Hours: 8 a.m.-4:30 p.m.
Piemont Augusta is the only hospital in the region to offer this life-saving heart failure treatment to those patients in need of left ventricular assistance. LVAD devices help your heart pump blood from one of the main pumping chambers to the rest of your body or to the other side of the heart. These pumps are implanted in your body. In most cases, they are connected to machinery outside your body.
Piedmont Augusta uses the HeartMate 3 device that circulates blood throughout the body when the heart is too weak to pump blood adequately on its own. It is sometimes called a “heart pump” or “VAD.” HeartMate 3 is a small implantable LVAD that represents a breakthrough in medical technology and has rapidly become the most widely used device of its kind in the world.
Is HeartMate 3 an artificial heart?
No. HeartMate 3 is not an artificial heart, nor is it a heart replacement. The patient’s native heart is not removed. HeartMate 3 attaches to the heart and is designed to assist – or take over – the pumping function of the patient’s left ventricle - the main pumping chamber of the heart.
How does HeartMate 3 work?
HeartMate 3 is designed to supplement the pumping function of the heart. The device is placed just below the diaphragm in the abdomen. It is attached to the left ventricle, and the aorta, the main artery that carries oxygenated blood from the left ventricle to the entire body. An external, wearable system that includes a small controller and two batteries is attached by an external driveline. The wearable system is either worn under or on top of clothing.
How does HeartMate 3 help a heart failure patient?
HeartMate 3 is designed to restore blood flow throughout the body, enabling the patient to breathe more easily and feel less fatigued. The patient’s organs will receive more blood than they did before receiving the LVAD, and this will likely improve their organ function. After receiving an LVAD, patients generally feel more energetic and are able to resume normal activities that they were unable to do prior to receiving the device
A ventricular assist device has 3 parts:
- A pump. The pump weighs 1 to 2 pounds (.5 to 1 kilogram). It is placed inside or outside of your belly.
- An electronic controller. The controller is like a small computer that controls how the pump works.
- Batteries. The batteries are carried outside your body. They are connected to the pump with a cable that goes into your belly.
You will need general anesthesia when your VAD is implanted. This will make you sleep and be pain-free during the procedure.
- The heart surgeon opens the middle of your chest with a surgical cut and then separates your breastbone. This allows access to your heart.
- Next, the surgeon will make space for the pump under your skin and tissue in the upper part of your belly wall.
- The surgeon will then place the pump in this space.
- A tube will connect the pump to your heart. Another tube will connect the pump to your aorta or one of your other major arteries. Another tube will be passed through your skin to connect the pump to the controller and batteries.
- The VAD will take blood from your ventricle (main pumping chamber of the heart) through the tube that leads to the pump. Then the device will pump the blood back out to one of your arteries and through your body.
- Surgery most often lasts 4 to 6 hours.
- There are other types of VADs that can be placed with less invasive techniques to help the left or right ventricle. However, these typically cannot provide as much flow (support) as the surgically implanted ones.
Why the Procedure Is Performed
You may need a VAD if you have severe heart failure that cannot be controlled with medicine, pacing devices, or other treatments. You may get this device while you are on a waiting list for a heart transplant. Some people who get a VAD are very ill and may already be on a heart-lung support machine.
Not everyone with severe heart failure is a good candidate for this procedure.
Risks for this surgery are:
- Blood clots in the legs that may travel to the lungs
- Blood clots that form in the device and can travel to other parts of the body
- Breathing problems
- Heart attack or stroke
- Allergic reactions to the anesthesia medicines used during surgery
Before the Procedure
Most people will already be in the hospital for treatment of their heart failure.
After the Procedure
Most people who are put on a VAD spend from a few to several days in the intensive care unit (ICU) after surgery. You may stay in the hospital from 2-8 weeks after you have had the pump placed. During this time you will learn how to care for the pump.
Less invasive VADs are not designed for ambulatory patients and those patients need to stay in the ICU for the duration of their use. They are sometimes used as a bridge to a surgical VAD or heart recovery.
A VAD may help people who have heart failure live longer. It may also help improve patients' quality of life.
