Aortic valve regurgitation — also called aortic regurgitation — is a type of heart valve disease. The valve between the lower left heart chamber and the body's main artery doesn't close tightly. As a result, some of the blood pumped out of the heart's main pumping chamber, called the left ventricle, leaks backward.
The leakage may prevent the heart from doing a good enough job of pumping blood to the rest of the body. You may feel tired and short of breath.
Aortic valve regurgitation can develop suddenly or over many years. Once the condition becomes severe, surgery often is needed to repair or replace the valve.
Most often, aortic valve regurgitation develops over time. You may have no symptoms for years. You might not realize that you have the condition. But sometimes, aortic valve regurgitation occurs suddenly. Usually, this is due to an infection of the valve.
As aortic valve regurgitation becomes worse, symptoms may include:
Call a member of your health care team right away if you have symptoms of aortic valve regurgitation.
Sometimes the first symptoms of aortic valve regurgitation are related to heart failure. Heart failure is a condition in which the heart can't pump blood as well as it should. Make an appointment with your health care team if you have:
These are common symptoms of heart failure.
The aortic valve is one of four valves that control blood flow through the heart. It separates the heart's main pumping chamber, called the left ventricle, and the body's main artery, called the aorta. The aortic valve has flaps, also called cusps or leaflets, that open and close once during each heartbeat.
In aortic valve regurgitation, the valve doesn't close properly. This causes blood to leak back into the lower left heart chamber, called the left ventricle. As a result, the chamber holds more blood. This could cause it to get larger and thicken.
At first, the larger left ventricle helps maintain good blood flow with more force. But eventually, the heart becomes weak.
Any condition that damages the aortic valve can cause aortic valve regurgitation. Causes may include:
Heart valve disease present at birth. Some people are born with an aortic valve that has only two cusps, called a bicuspid valve. Others are born with connected cusps rather than the typical three separate ones. Sometimes the valve may have only one cusp, called a unicuspid valve. Other times, there are four cusps, called a quadricuspid valve.
Having a parent or sibling with a bicuspid valve raises your risk of the condition. But you can have a bicuspid valve even if you don't have a family history of the condition.
Things that raise the risk of aortic valve regurgitation include:
The condition also can happen without any known risk factors.
Complications of aortic valve regurgitation can include:
If you have any type of heart disease, get regular health checkups.
If you have a parent, child or sibling with a bicuspid aortic valve, you should have an imaging test called an echocardiogram. This can check for aortic valve regurgitation. Early diagnosis of heart valve disease, such as aortic valve regurgitation, is important. Doing so may make the condition easier to treat.
Also, take steps to prevent conditions that can raise the risk of aortic valve regurgitation. For example:
To diagnose aortic valve regurgitation, a member of your health care team examines you. You usually are asked questions about your symptoms and health history. You also might be asked about your family's health history.
Your blood pressure is checked using a cuff, usually placed around your arm. A device called a stethoscope is used to listen to your heart. Your health care professional may hear an irregular sound called a heart murmur.
You may be referred to a doctor trained in heart diseases, called a cardiologist.
Treatment of aortic valve regurgitation depends on:
The goals of aortic valve regurgitation treatment are to ease symptoms and prevent complications.
If your symptoms are mild or you don't have symptoms, you may only need regular health checkups. You may need regular echocardiograms to check the health of the aortic valve. Heart-healthy lifestyle changes also are usually recommended.
If you have aortic valve regurgitation, you may be given medicines to:
Surgery may be needed to repair or replace the diseased valve, especially if the condition and symptoms are severe. Heart valve surgery may be needed even if aortic regurgitation isn't severe or when there are no symptoms.
The decision to repair or replace a damaged aortic valve depends on:
If you're having another heart surgery, surgeons may do aortic valve surgery at the same time.
Surgery to repair or replace an aortic valve may be done as open-heart surgery. This involves a cut, also called an incision, in the chest. Sometimes surgeons can do minimally invasive heart surgery to replace the aortic valve.
Surgery for aortic valve regurgitation includes:
Aortic valve replacement. The surgeon removes the damaged valve and replaces it. The replacement might be a mechanical valve or one made from cow, pig or human heart tissue. A tissue valve also is called a biological tissue valve.
Sometimes, surgeons can do minimally invasive heart surgery to replace the aortic valve. This procedure is called transcatheter aortic valve replacement (TAVR). It uses smaller incisions than those used in open-heart surgery.
Sometimes the aortic valve is replaced with your own lung valve, also called the pulmonary valve. Your pulmonary valve is replaced with a biological lung tissue valve from a deceased donor. This more complicated surgery is called the Ross procedure.
Biological tissue valves break down over time. Eventually, they may need to be replaced. People with mechanical valves need blood thinners for life to prevent blood clots. Ask your health care team about the benefits and risks of each type of valve.
While lifestyle changes can't prevent or treat your condition, your health care team might suggest that you practice some heart-healthy habits. These may include:
Careful and regular checkups are needed for those who have heart valve disease, including aortic valve regurgitation, during pregnancy. If you have a severe heart valve condition, you might be told not to get pregnant to reduce the risk of complications.
If you think you might have symptoms of heart valve disease, make an appointment for a health checkup. You may be referred to a doctor trained in heart diseases. This doctor is called a cardiologist.
If you have aortic valve regurgitation, consider being cared for by a medical team that specializes in heart valve disease.
