Infectious Diseases - Heart Flashcards
endocarditis mainly affects what in the heart
the valves
endocarditis mainly affects what in the heart
the valves
which kind of endocarditis affects normal valves
acute endocarditis
main cause of acute endocarditis is
s. aureus
what valve is mainly affected in acute endocaridits
aortic valve
which kind of endocarditis is an emergency and needs ICU attention because of the possibility of acute heart failure
acute endocarditis
what are the two tx for acute endocarditis
vancomycin and Rifampin (ahminoglycosides)
what are 6 things that can cause deformed mitral valves
- Rheumatic Fever
- Bicuspid Aortic Valve
- Aortic Sclerosis
- Tetralogy of Fallot
- PDA
- Congenital heart disease
why does PDA cause mitral valve deformity
because it allows for more heart to be put into the left heart, therefore putting more pressure on the mitral valve leading to deformity
organisms that cause subacute endocarditis in deformed valves
s. viridian’s and enterococci(group D strep)
which organism can cause endocarditis and is 50% of the time associated with colon cancer
S. Bovis
how long is early prosthetic endocarditis?
how long is late prosthetic endocarditis
> 2 months
what can cause early prosthetic endocarditis
s. epidemis
s. aureus
s. viridans
what can cause late prosthetic endocarditis
s. viridian’s
s. aureus
s. epididymis
how to dx prosthetic heart valve endocarditis
blood culture (3sets) 3 different times

s. viridian’s
s. aureus
s. epididymis
osier’s nodes, janway lesions. roth spots and immune complex deposition is seen in
subacute endocarditis
how to dx prosthetic heart valve endocarditis
blood culture (3sets) 3 different times
what is inside the blood culture vile that allows the bacteria to grow
BHI-Brain Heart Infusion
what will show the vegetation’s in the heart
echocardiogram (transesophageal is the best)
what is the treatment for endocarditis caused by s. viridian’s
penicillin
what affects the mitral valve by first causing regurgitation and then later in life stenosis of the valve
Rheumatic fever
