nonbacterial thrombotic 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.

nonbacterial thrombotic endocarditis

[-baktir′ē·əl]

Etymology: L, non + bakerion, small rod

one of the three main types of endocarditis, characterized by various kinds of lesions affecting the heart valves, most often on the left side of the heart. The disease may be the first step in the development of bacterial endocarditis, and the lesions may cause peripheral arterial embolisms, resulting in death. The disease equally affects men and women between 18 and 90 years of age and causes heart murmurs in about 30% of cases. There is no successful treatment, but anticoagulation therapy may be used to reduce the incidence of peripheral arterial embolism. See also Libman-Sacks endocarditis.

endocarditis

exudative and proliferative inflammatory alterations of the endocardium, 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.

Lesions on the valves may interfere with the ejection of blood from the heart by causing insufficiency or stenosis of the valves. Murmurs associated with the heart sounds are the major manifestation and if interference with the blood flow is sufficiently severe congestive heart failure develops. The further hazard with endocarditis, especially if it is bacterial in origin, is that of septic emboli in the lungs or in the other organs.

bacterial endocarditis

infectious endocarditis, acute or subacute, caused by various bacteria, including streptococci, staphylococci, enterococci and gram-negative bacilli. Of particular interest in animals is the predilection of Erysipelothrix rhusiopathiae to cause endocarditis, epecially in pigs.

ductal endocarditis

due to thrombosis in a persistent ductus arteriosus with resulting mural inflammation.

infectious endocarditis, infective endocarditis

that due to infection with microorganisms, especially bacteria and fungi.

mural endocarditis

that affecting the lining of the walls of the heart chambers only.

nonbacterial thrombotic endocarditis

that in which the vegetations, single or multiple, consist of fibrin and other blood elements.

parietal endocarditis

mural endocarditis.

tuberculous endocarditis

that resulting from extension of a tuberculous infection from the pericardium and myocardium.

valvular endocarditis

that affecting the membrane over the heart valves only.

vegetative endocarditis

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