infectious endocarditis

endocarditis /en·do·car·di·tis/ (-kahr-di´tis) exudative and proliferative inflammatory alterations of the endocardium, usually characterized by the presence of vegetations on the surface of the endocardium or in the endocardium itself, and most commonly involving a heart valve, but also affecting the inner lining of the cardiac chambers or the endocardium elsewhere.endocardit´ic

atypical verrucous endocarditis  Libman-Sacks e.

bacterial endocarditis  infectious endocarditis caused by various bacteria, including streptococci, staphylococci, enterococci, gonococci, and gram-negative bacilli.

infectious endocarditis , infective endocarditis that due to infection with microorganisms, especially bacteria and fungi; currently classified on the basis of etiology or underlying anatomy.

Libman-Sacks endocarditis  nonbacterial endocarditis found in association with systemic lupus erythematosus, usually occurring on the atrioventricular valves.

Löffler's endocarditis , Löffler's parietal fibroplastic endocarditis endocarditis associated with eosinophilia, marked by fibroplastic thickening of the endocardium, resulting in congestive heart failure, persistent tachycardia, hepatomegaly, splenomegaly, serous effusions into the pleural cavity, and edema of the limbs.

mycotic endocarditis  infectious endocarditis, usually subacute, due to various fungi, most commonly Candida, Aspergillus, and Histoplasma.

nonbacterial thrombotic endocarditis  (NBTE) that usually occurring in chronic debilitating disease, characterized by noninfected vegetations consisting of fibrin and other blood elements and susceptible to embolization.

prosthetic valve endocarditis  infectious endocarditis as a complication of implantation of a prosthetic valve in the heart; the vegetations usually occur along the line of suture.

rheumatic endocarditis  that associated with rheumatic fever; more accurately termed rheumatic valvulitis when an entire valve is involved.

rickettsial endocarditis  endocarditis caused by invasion of the heart valves with Coxiella burnetii; it is a sequela of Q fever, usually occurring in persons who have had rheumatic fever.

vegetative endocarditis , verrucous endocarditis endocarditis, infectious or noninfectious, the characteristic lesions of which are vegetations or verrucae on the endocardium.

infectious endocarditis,

endocarditis caused by infection with microorganisms, especially bacteria and fungi. It was formerly classified according to course as acute and subacute: the acute form is usually caused by staphylococci, pneumococci, gonococci, or streptococci, involves a normal heart valve, and has a short history and rapid course; the subacute form usually is caused by viridans or fecal streptococci or fungi, affects damaged heart valves, and has a prolonged course. Because underlying causes and available therapies have changed, this division has little current clinical validity and has been largely replaced by classification on the basis of cause or underlying anatomy.
