Information for Patients


Endocarditis, also called infective endocarditis (IE), is an inflammation of the inner lining of the heart. The most common type, bacterial endocarditis, occurs when germs enter your heart. These germs come through your bloodstream from another part of your body, often your mouth. Bacterial endocarditis can damage your heart valves. If untreated, it can be life-threatening. It is rare in healthy hearts.

Risk factors include having

  • An abnormal or damaged heart valve
  • An artificial heart valve
  • Congenital heart defects

The signs and symptoms of IE can vary from person to person. They also can vary over time in the same person. Symptoms you might notice include fever, shortness of breath, fluid buildup in your arms or legs, tiny red spots on your skin, and weight loss. Your doctor will diagnose IE based on your risk factors, medical history, signs and symptoms, and lab and heart tests.

Early treatment can help you avoid complications. Treatment usually involves high-dose antibiotics. If your heart valve is damaged, you may need surgery.

If you're at risk for IE, brush and floss your teeth regularly, and have regular dental checkups. Germs from a gum infection can enter your bloodstream. If you are at high risk, your doctor might prescribe antibiotics before dental work and certain types of surgery.

Heart Valve Diseases

Also called: Valvular heart disease

Your heart has four valves. Normally, these valves open to let blood flow through or out of your heart, and then shut to keep it from flowing backward. But sometimes they don't work properly. If they don't, you could have

  • Regurgitation - when blood leaks back through the valve in the wrong direction
  • Mitral valve prolapse - when one of the valves, the mitral valve, has "floppy" flaps and doesn't close tightly. It's one of the most common heart valve conditions. Sometimes it causes regurgitation.
  • Stenosis - when the valve doesn't open enough and blocks blood flow

Valve problems can be present at birth or caused by infections, heart attacks, or heart disease or damage. The main sign of heart valve disease is an unusual heartbeat sound called a heart murmur. Your doctor can hear a heart murmur with a stethoscope. But many people have heart murmurs without having a problem. Heart tests can show if you have a heart valve disease. Some valve problems are minor and do not need treatment. Others might require medicine, medical procedures, or surgery to repair or replace the valve.
