Infective endocarditis is an infection of the inner surface of the heart (endocardium), usually the valves. [1] Signs and symptoms may include fever, small areas of bleeding into the skin, heart murmur, feeling tired, and low red blood cell count.
Endocarditis is an inflammation of the inner layer of the heart, the endocardium.It usually involves the heart valves.Other structures that may be involved include the interventricular septum, the chordae tendineae, the mural endocardium, or the surfaces of intracardiac devices.
If the person had aortic regurgitation, meaning blood’s going from the higher pressure aorta to the lower pressure ventricle, then vegetations would tend to be located on the lower pressure ventricular surface of the valve. Infective endocarditis used to be classified into groups like acute and subacute based on how quickly the infection ...
Nonbacterial thrombotic endocarditis (NBTE) is a form of endocarditis in which small sterile vegetations are deposited on the valve leaflets. Formerly known as marantic endocarditis , which comes from the Greek marantikos , meaning "wasting away". [ 1 ]
Histopathology of a vegetation of bacterial endocarditis, taken from a valve repair, H&E stain. Abnormal growths in the heart associated with endocarditis In medicine, a vegetation is an abnormal growth [ 1 ] named for its similarity to natural vegetation .
Endocarditis of the valves can lead to regurgitation through that valve, which is seen in the tricuspid, mitral, and aortic valves. [16] Certain medications have been associated with valvular heart disease, most prominently ergotamine derivatives pergolide and cabergoline .
The following outline is provided as an overview of and topical guide to cardiology, the branch of medicine dealing with disorders of the human heart. [1] The field includes medical diagnosis and treatment of congenital heart defects, coronary artery disease, heart failure, valvular heart disease and electrophysiology.
Aortic regurgitation (AR), also known as aortic insufficiency (AI), is the leaking of the aortic valve of the heart that causes blood to flow in the reverse direction during ventricular diastole, from the aorta into the left ventricle. As a consequence, the cardiac muscle is forced to work harder than normal.
