Endocarditis

What Is It?

Endocarditis, also called infective endocarditis, is an infection and inflammation of the heart valves and the inner lining of the heart chambers, which is called the endocardium. Endocarditis occurs when infectious organisms, such as bacteria or fungi, enter the bloodstream and settle in the heart. In most cases, these organisms are streptococci ("strep"), staphylococci ("staph") or species of bacteria that normally live on body surfaces.

The infecting organism enters the bloodstream through a break in the skin caused by a skin disorder or injury; a medical or dental procedure; or a skin prick, especially among intravenous drug users.
