Question 2
Question
The infective endocarditis is characterized by:
Answer
-
vegetation often occurs at the point where the pressure is higher (at the chamber side of the mitral valve, the aortic side of the aortic valve)
-
mature vegetation consisting of cardiomyocytes, fibroblasts, and inflammatory cells of the bacterium
-
cerebral embolism may occur in more than 2/3 of patients
-
the native Valve is a frequent obstruction due to vegetation
-
Endocarditis is reflected by vegetation on the valves, abscesses in the field of valves and valve perforation
Question 3
Question
What are the main clinical diagnostic criteria for infective endocarditis (under the scheme Duke):
Answer
-
Ultrasound evidence of endocardial involvement (vegetation, abscess)
-
Oslerjevi nodules
-
positive blood culture
-
major arterial embolism
-
artificial cardiac valve
Question 4
Question
Typical laboratory findings in infectious endocarditis are:
Answer
-
Leukocytopenia
-
microscopic hematuria
-
erythrocyte sedimentation rate slowed
-
elevated CRP

Janeway lesions
Question 5
Question
Infectious endocarditis caused by streptococcus viridans treated:
Answer
-
penicillin G intravenously for 4 weeks; the first 14 days an additional aminoglycoside
-
with azithromycin, 5 days orally
-
with a combination of ampksicilin / clavulanic acid, for 14 days orally
-
with a combination of ampksicilin / clavulanic acid, for 14 days intravenously
-
penicillin G intravenously in combination with an aminoglycoside, for 14 days

Question 7
Question
What is the recommended antibiotic scheme for prevention of infectious endocarditis in high-risk surgery:
Answer
-
amoxicillin 2 g orally 1 hour prior to surgery
-
amoxicillin 1 g intravenously 3g before and 3 hours after the procedure
-
amoxicillin + clavulanate 1g 1g before and 12 hours after surgery
-
azithromycin 500 mg 1 day before and 2 days after surgery
-
imipenem 500 mg intravenously during surgery
Question 8
Question
What is characteristic of rheumatic fever:
Answer

rheumatoid arthritis treated with high-dose acetylsalicylic acid
-
rheumatoid carditis treated with steroids
-
the acute phase is characterized by a migratory polyarthritis
-
only affects endocardial

-
the treatment with antibiotics is required at least 4 weeks
-
endocarditis can not cause valve regurgitation

For healthy and more frequently, the modified native Valve
-
The valve prosthesis
-
Only the previously modified Valve
-
On the atrial side of the mitral valve and aortic valve chamber side
