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.
