disorders of the endocardium Flashcards
what are the valvular disorders?
heart murmur, stenosis, and regurgitation
what is stenosis?
nability of a valve to open fully during systole
what are they types of causes of stenosis and regurgitation?
congenital and acquired
what causes acquired stenosis?
heumatic heart disease, bacterial endocarditis
what types of stenosis is there?
aortic and mitral
aortic valve stenosis lead to what?
L ventricular hypertrophy
why do the atriums dilate?
because they empty by gravity so they don’t typically hypertrophic
what is regurgitation?
when valves fail to close properly, causing backflow of blood
what are the types of regurgitation?
aortic and mitral
what happens to the SV initially in aortic regurgitation?
it increases
what are the causes of regurgitation?
bacterial endocarditis or rheumatic heart disease
what is the most frequent target of endothelial cells in rheumatic heart disease?
the mitral valve
