Myocardial abscess is a suppurative infection of myocardium, endocardium, native or prosthetic valves, perivalvular structures and cardiac conduction system. It develops in about 20% of patients with infective endocarditis. Due to avascular and fibrous structures, valvular regions are commonly involved.
