Infective endocarditis (infective endocarditis) refers to the inflammation of heart valve or ventricular wall endometrium caused by direct infection by bacteria, fungi and other microorganisms (such as virus, rickettsia, chlamydia, spirochadium, etc.). Non-infective endocarditis caused by rheumatic fever, rheumatoid, systemic lupus erythematosus, etc. This disease was called bacterial endocarditis in the past, but it is not used because it is not comprehensive enough.
