Q

In acute rheumatic fever, watch would you expect to see as a result of the endocarditis?

A
  • edematous and thickened valves with foci of fibrinoid necrosis
  • tiny wart like vegetations along the lines of closure of the mitral valve → no effect on cardiac function

Q

Calcified aortic stenosis most commonly occurs in (3)

A
  • elderly patients
  • congenital bicuspid aortic vale
  • rheumatic heart disease
18
Q

____________ is a valvular disease that can be a complication of Marfan Syndrome

A

mitral valve prolapse

19
Q

What heart sound is indicative of mitral valve prolapse?

A

Mid systolic click due to the ballooning of the leaflets into the left atrium during systole

20
Q

In mitral valve prolapse there is ________ of the ___________ layer of the valve and ________ of the _________ layer

A

Thinning of the fibrosa layer and thickening/expansion of the spongiosa layer

21
Q

Which layers of the valve are affected in mitral valve prolapse?

A

Spongiosa: expansion (accumulation of CT)
Fibrosa: thinning

22
Q

The midsystolic click seen in________ is de to when _______

A

Mitral valve prolapse; due to the abrupt tension on the leaflets and chordae tendonae when the valve tries to close

23
Q

Typically in ________ endocarditis, there is infection of a normal valve

A

Acute;

Destructive and fulminant and caused by high virulent organisms

24
Q

Subacute endocarditis occurs in normal/abnormal valves

A

Abnormal

Less destruction and most patients recover with appropriate therapy

25
Microorganisms in infective endocarditis adhere to the deposits of platelets an fibrin via _____ and ________
Fibronectin and adhesion factors such as polysaccharides
26
describe the vegetations seen in acute IE
friable, bulky and potential destructive and contain fibrin
27
how are the vegetations different in subacute IE vs acute IE
subacute: vegetations are less friable and have lesser degree of valve destruction. and ring abscesses are uncommon. will see chronic inflammatory infiltrate, granulation tissue, fibrosis and calcification
28
what are clinical features of infective endocarditis?
- finger clubbing - splinter hemorrhages under nail beds - Osler nodes: tender subcutaneous nodules on finger tips - Janeway lesions: non tender maculae on palms and soles - Roth spots: retinal hemorrhages
29
splenomegaly and weight loss are features seen in acute/subacute IE?
subacute; | other features of subacute: CHANGING murmurs and low grade fever w/ malaise
30
the release of the bacterial antigen in IE lets to what host consequences
causes immune complex formation leading to: glomerulonephritis, Osler's nodes, and Roth spots
31
in addition to Duke's criteria, what else is needed for diagnosis?
repeated blood cultures and echocardiography
32
what is marantic endocarditis?
presence of STERILE thrombi on the leaflets of previously normal valves (seen in debilitated patients like those with cancer)
33
marantic endocarditis / NBTE (non bacterial thrombotic endocarditis) is associated with:
- endothelial abnormalities - hypercoagulable states - adenocarcinomas
34
sterile vegetation on cardiac valves in patients with SLE is known as what disease?
Libman Sacks endocarditis (LSE in SLE)
35
what kind of vegetations are seen in Libman sacks endocarditis?
STERILE
36
what are some clinical features of someone suffering from acute bacterial endocarditis?
- high grade fever w/ chills - NEW cardiac murmur - features of septicemia
37
in calcific aortic stenosis, the calcium is deposited ____________ leading to ______
behind the valve cusps and thus extend into the sinus of valsalva → coronary ischemia
38
_________ and _______ lesions are due to the fragmentation of the vegetations in IE
splinter hemorrhage and Janeway lesion
39
life long anticoagulation and thus risk for hemorrhage is a complication of ______ type of prosthetic valve
mechanical;
40
what are some complications of mechanic prosthetic valves?
- thrombo embolism - life long anitcoagulation (risk for hemorrhage) - hemolysis (RBC destruction) - paravascular leak due to inadequate healing - IE
41
because tissue valves (bioprosthetic valves) are less durable, what are some possible complications?
- matrix deterioration → rigidity and calcification → stenosis and can perforate
42
do you need anticoagulation for bioprosthetic valves?
NO (only with mechanical)
