The valve in this preparation is healthy, so this is a case of ''acute'' infective endocarditis. Many types of bacteria can cause this, like streptococci, staphylococci and enterococci. | The valve in this preparation is healthy, so this is a case of ''acute'' infective endocarditis.

In any form of endocarditis will form ''vegetations'' on the valves. Vegetations are small growths that contain fibrin, leukocytes, RBCs, platelets and, if the endocarditis is infective, bacteria as well. Vegetations usually grow on the superior side of the valve. The consequences of endocarditis can be divided into systemic and local. The systemic consequences can be embolization and sepsis. The local consequences can be perforation of the valve, leading to heart failure, or the bacteria can spread from the vegetation to the myocardium. This forms a phlegmone that will eventually form a characteristic type of abscess called ''ring abscess''.[[File:Infective endocarditis prep.jpg|center|thumb|Infective endocarditis prep.
