Having aortic valve stenosis means that the valve between your heart and the large blood vessel that carries blood to the body (aorta) has narrowed. That forces the heart to pump harder to get enough blood through the valve. As stenosis gets worse, the valve gets narrower. This can cause symptoms. Symptoms include chest pain, dizziness, fainting, or shortness of breath.
Your doctor will check your heart regularly. You may take medicine to lower blood pressure or cholesterol. If the stenosis gets worse, you may choose to have the valve replaced.
Aortic valve stenosis is a narrowing of the aortic valve between the lower left chamber of the heart and the aorta, which supplies blood to the body. A narrowed aortic valve forces the lower left chamber of the heart to pump harder to get enough blood through the valve.
When you have aortic valve stenosis, the valve gets narrower over time. Your heart has to work harder to pump blood through the aortic valve. Symptoms include chest pain, dizziness, and shortness of breath. Stenosis can lead to heart failure. You may choose to have the valve replaced if the stenosis gets worse.
Aortic valve stenosis is a slow process. For many years, even decades, you may not feel any symptoms. But at some point, the valve may become so narrow that you start having symptoms. Symptoms are often brought on by exercise, when the heart has to work harder.
As aortic valve stenosis gets worse, you may have symptoms such as:
Your doctor will check your heart regularly. Your doctor will recommend a heart-healthy lifestyle. You may take medicine that lowers blood pressure or cholesterol. You may choose to have surgery or a procedure to replace the valve. Some people have a procedure to widen the valve.
Most people find out they have aortic valve stenosis when their doctor hears a heart murmur during a physical exam. To be sure of the diagnosis, your doctor may want you to have an echocardiogram. You may have other tests to help your doctor judge how well your heart is working.
You can live a full and active life by doing things that help keep your heart and body healthy. Here's how.
If you have severe stenosis, you may choose to have your aortic valve replaced. Valve replacement is done to help you feel better and live longer.
To help decide about valve replacement, you and your doctor will look at your overall health, your heart health, if you have symptoms, and how bad the stenosis is.
A valve can be replaced with a surgery or a procedure. You and your doctor can work together to decide which way is right for you. The ways to replace a valve are:
Aortic valve stenosis can be caused by calcium buildup on the valve. It can also be caused by a heart defect that you were born with, such as a bicuspid aortic valve. It may also be caused by rheumatic fever, which can damage the valve.
Aortic valve stenosis is a narrowing of the aortic valve. The aortic valve allows blood to flow from the heart's lower left chamber (ventricle) into the aorta and to the body. Stenosis prevents the valve from opening properly, forcing the heart to work harder to pump blood through the valve. This causes pressure to build up in the left ventricle and thickens the heart muscle.
Your heart can make up for aortic valve stenosis and the extra pressure for a long time. But at some point, it may not be able to keep up the extra effort of pumping blood through the narrowed valve. This can lead to heart failure.
Call 911 anytime you think you may need emergency care. For example, call if:
After you call 911, the operator may tell you to chew 1 adult-strength or 2 to 4 low-dose aspirin. Wait for an ambulance. Do not try to drive yourself.
Call your doctor now or seek immediate medical care if:
Watch closely for changes in your health, and be sure to contact your doctor if you have any problems.
