Endocarditis is an inflammation of the lining of the heart valves that is most often caused by infection. While not very common, it can be a very serious disease. Men are twice as likely to be affected as women.
There are two types of endocarditis: infective and non-infective. With prompt treatment, the majority of people with infective endocarditis will survive. Non-infective endocarditis is more difficult to treat.
