The mitral valve lets blood flow from the upper to the lower heart chamber on the left side of the heart. Mitral valve regurgitation occurs when the valve can't close all the way and blood backs up into the upper chamber of the heart. This causes the heart to work harder to pump the extra blood.
You may have this condition for many years without having problems. But over time, it can weaken the heart and lead to heart failure.
This condition can be caused by many things, including mitral valve prolapse, calcium buildup on the valve, coronary artery disease, and heart failure.
Your doctor will check your heart regularly. Your doctor will likely recommend a heart-healthy lifestyle. You may take medicine to treat a problem that is causing, or was caused by, the regurgitation. If the disease becomes severe, you may choose to have the valve repaired or replaced.
Mitral valve regurgitation (MR) is the leaking or backflow of blood through the valve between the upper left heart chamber (atrium) and the lower left heart chamber (ventricle). If serious, this condition can lead to a backup of blood in the left atrium and the lungs, cause enlargement of and damage to the left ventricle, and lead to heart failure.
Symptoms of chronic mitral valve regurgitation may take decades to appear. They include being tired or short of breath when you're active. A heart murmur might be the first sign your doctor notices. Acute mitral regurgitation happens suddenly and is an emergency. Symptoms include severe shortness of breath, lightheadedness, and weakness, and chest pain.
For chronic mitral regurgitation, you may take medicines to treat problems caused by the regurgitation or to treat a heart problem that is causing it. Your doctor will check your heart regularly. You may choose to repair or replace the valve. For acute regurgitation, you likely need valve repair or replacement right away.
When your doctor suspects that you have mitral valve regurgitation, you will be asked about your past health and have a physical exam. To diagnose the problem and check your heart, you'll likely have an echocardiogram. You may have other tests to help your doctor see how well your heart is working.
If you have severe chronic mitral valve regurgitation, you may choose to have the mitral valve repaired or replaced. The goal is for blood to flow more normally through the valve. Valve repair may be done with surgery or a catheter procedure. Valve replacement is done with a surgery. You and your doctor can decide if repair or replacement is right for you.
Valve repair may be done to help the valve work better. Or the valve may be replaced. Repair or replacement helps prevent damage to the heart that can be caused by the regurgitation.
Valve repair or replacement may be done to help relieve symptoms, help you live longer, and improve your quality of life. Repair or replacement cannot cure secondary mitral regurgitation because it is caused by another heart problem.
With acute mitral regurgitation, urgent repair or replacement surgery is usually needed.
Primary mitral valve regurgitation may be caused by problems like mitral valve prolapse or calcium buildup on the mitral valve. Secondary regurgitation may be caused by coronary artery disease or heart failure. Acute regurgitation is caused by a problem that happens all of a sudden, such as a heart attack.
Mitral valve regurgitation happens when the mitral valve does not close tightly enough after blood flows through the valve into the lower chamber of the heart. This makes a small opening in the valve even when the valve is closed. This opening can let blood leak (regurgitate) back into the upper chamber of the heart.
