What is Endocarditis?
Endocarditis is an inflammation of the inner layer of the heart, the endocardium. It usually involves the heart valves (native or prosthetic valves). Other structures that may be involved include the interventricular septum, the chordae tendineae, the mural endocardium, or even the surfaces of intracardiac devices. Endocarditis is characterized by a prototypic lesion, the vegetation.
