Mitral Valve Regurgitation
Mitral valve regurgitation is the name for one of those times when your blood isn’t going where it should. With this condition, some of it leaks backward instead of flowing out to the rest of your body.
The most common reason this happens is because the mitral valve is damaged. This can be either from birth or because of a heart attack, which can weaken the tissue around it. You might hear a doctor say a valve is
prolapsed if it doesn’t close up the way it should.
Other possible causes:
A buildup of calcium
Rheumatic fever, which can develop as a result of strep throat
A type of bacterial infection called
infective endocarditis,which attacks the lining of your heart’s chambers and valves
Heart palpitations, which happen when your heart skips a beat. They produce feelings in your chest that can range from fluttering to pounding. They may be more likely to happen when you’re lying on your left side.
Shortness of breath
Doctors usually find a problem with your heart valve by sound. If blood is leaking back into your left atrium, it will produce a murmur or a whooshing sound. Your doctor can hear that through a stethoscope.
A common follow-up test is called an echocardiogram. This uses sound waves to make a picture of your beating heart, similar to the ultrasound tests given to pregnant women.
Your doctor might also want to get a CT or MRI scan of your chest to help figure out what’s going on. These are just two more ways to get a visual picture of your insides.
Severe regurgitation can cause blood clots, gel-like clumps that can create serious problems if they get to the lungs or brain.
The condition can also cause fluid to build up in the lungs, straining the right side of the heart.
If you have regurgitation, less blood is going to your body. Your heart works harder to make up for the shortfall. If this goes on long enough, your heart could enlarge, making it harder to pump blood and raising the risk of heart failure.
It also can lead to an irregular, or uneven, heartbeat or a stroke.
Medications can’t actually fix a valve problem, but they can target other things that make regurgitation worse. Drugs called diuretics (or
water pills) can lessen fluid buildups.
Blood thinners can help prevent clots if you have atrial fibrillation. You can take something if you have high blood pressure, which makes regurgitation worse.
In more severe cases, you might need an operation.
Sometimes, a surgeon can fix your valve. If it has to be replaced, they can implant either a man-made device or one taken from a cow, a pig, or a person who died and donated the organ.
They may also use a catheter to insert a clothespin-like device called a MitraClip which helps the valve close more completely and improve blood flow.
People who have had valve surgery are often asked to take antibiotics before they have dental work or other surgery to prevent endocarditis, or infection of the heart valves or inner lining of the heart.
You should ask your doctor whether you’ll need to take them.
