Endocarditis is an infection of the endocardium, which is the inner lining of your heart chambers and heart valves.
Endocarditis generally occurs when bacteria, fungi or other germs from another part of your body, such as your mouth, spread through your bloodstream and attach to damaged areas in your heart. If it's not treated quickly, endocarditis can damage or destroy your heart valves and can lead to life-threatening complications. Treatments for endocarditis include antibiotics and, in certain cases, surgery.
Since there are many ways to develop endocarditis, your doctor might not be able to pinpoint the exact cause of your condition. However, people at greatest risk of endocarditis usually have damaged heart valves, artificial heart valves or other heart defects.

Endocarditis may develop slowly or suddenly, depending on what germs are causing the infection and whether you have any underlying heart problems. Endocarditis signs and symptoms can vary from person to person.
Common signs and symptoms of endocarditis include:
Endocarditis can also cause symptoms that are more uncommon. These include:
If you develop signs or symptoms of endocarditis, and if they don't go away, see your doctor as soon as possible â especially if you have risk factors for this serious infection, such as a heart defect or a previous case of endocarditis.
Although less serious conditions can cause similar signs and symptoms, you won't know for sure until you're evaluated by your doctor.

Endocarditis occurs when germs enter your bloodstream, travel to your heart, and attach to abnormal heart valves or damaged heart tissue. Certain types of bacteria cause most cases, but fungi or other microorganisms also may be responsible.
Usually, your immune system destroys harmful bacteria that make it into your bloodstream. Even if bacteria reach your heart, they may pass through without causing an infection. However, bacteria that live in your mouth, throat or other parts of your body, such as your skin or your gut, can sometimes cause serious infections like endocarditis under the right circumstances.
Bacteria, fungi or other germs that cause endocarditis might enter your bloodstream through:
Bacteria can more easily attach to the lining of your heart (endocardium), if the lining's surface is rough. You're also more likely to develop endocarditis if you have faulty, diseased or damaged heart valves. However, endocarditis does occasionally occur in previously healthy individuals.

Your doctor may suspect endocarditis based on your medical history, signs and symptoms you're experiencing, and your test results. A diagnosis of endocarditis is usually based on several factors instead of a single positive test result or symptom.
Your doctor may order several tests to help make a positive diagnosis, including:
Echocardiogram. An echocardiogram uses sound waves to produce images of your heart while it's beating. This test is often used to check for signs of infection. Your doctor may use two different types of echocardiograms to help diagnose endocarditis.
In a transthoracic echocardiogram, sound waves directed at your heart from a wandlike device (transducer) held on your chest produce video images of your heart in motion. This test can help your doctor look at your heart's structure and check it for any signs of infection or damage.
Doctors may conduct another type of echocardiogram called a transesophogeal echocardiogram to get a closer look at your heart valves. During this test, a small transducer attached to the end of a tube is inserted down the tube leading from your mouth to your stomach (esophagus). This test can allow your doctor to get much more detailed pictures of your heart than is possible with a transthoracic echocardiogram.

In endocarditis, clumps of bacteria and cell fragments form in your heart at the site of the infection. These clumps, called vegetations, can break loose and travel to your brain, lungs, abdominal organs, kidneys or limbs. As a result, endocarditis can cause several major complications, including:

You can help prevent endocarditis in several ways, including:
Certain dental and medical procedures may allow bacteria to enter your bloodstream. For some people with heart disease or damaged or diseased heart valves, taking antibiotics before these procedures can help destroy or control the harmful bacteria that may lead to endocarditis. This is because these people are more at risk of developing endocarditis after having these procedures.
In the past, doctors gave antibiotics to many people before dental or other surgical procedures, such as procedures involving the intestinal or urinary tracts, even if they weren't at high risk of developing endocarditis. However, antibiotics are no longer recommended before all dental or other surgical procedures, or for all people. As doctors have learned more about endocarditis prevention, they've realized endocarditis is much more likely to occur from exposure to random germs than from a standard dental exam or surgery.
If you're at risk of endocarditis, let your doctor and dentist know before having any dental work. They will decide whether you need antibiotics before any dental procedures.
It's still important to take good care of your teeth through brushing and flossing, since doctors have some concern that infections in your mouth from poor oral hygiene might increase the risk of germs entering your bloodstream. In addition to brushing and flossing, regular dental exams are an important part of maintaining good oral health.

If you're at risk of endocarditis, let all of your health care providers know. You may want to request an endocarditis wallet card from the American Heart Association. Check with your local chapter or print the card from the association's website.

If your heart is healthy, you could be less likely to develop endocarditis, although it is still possible. The germs that cause infection tend to stick to and multiply on damaged or surgically implanted heart valves, or on endocardium that has a rough surface.
People at highest risk of endocarditis are those who have:
