Supravalvular aortic stenosis 4. All of the following are related to rheumatic fever, except: a. Fibrinoid inflammation of the pericardium b. Pancarditis c. Deformation of the valve d. Foci of fibrinoid degeneration in the endocardium e. Deformation of joints 5. What is present in rheumatic heart disease? a. Ballooning of the mitral valve b. Cross reactant antibodies to staphylococcus aureus c. Myocardial infiltration with PMNs d. Fibroid deformation of the mitral valve e. Annular abscess 6. Which immunological mechanism is involved in the development of aseptic vasculitis in patients with infective endocarditis? a. Cytotoxic T8 lymphocytic reaction b. Immune complex c. Cross reacting antibodies d. Antinuclear antibodies e. Anaphylaxis 7. All of the following are related to nonbacterial thrombotic endocarditis, except: a. Extensive burns b. Advanced malignancy c. Hypercoagulability d. Acute valvular inflammation e. Thromboembolism -1- 8. What is correct regarding atherosclerosis? a. Atheroma at the aortic valve is called verruca b. LDL particles enter the intima of the artery through vasa vasorum c. Antischkow cell appear sometimes in atheromas and participate in phagocytosis d. Smooth muscle cells participate in phagocytosis in the atheroma e. Monocytes that migrate to the atheroma secrete HDL 9. All of the following are related to atheromatous plaque disruption in a coronary artery, except: a. Bleeding into the atheroma b. Ulceration of the atheroma c. Calcification of the atheroma d. Erosion of the atheroma e. Rupture in the fibrous cap of the atheroma 10. What is correct regarding fatty streak? a. Fatty streaks appear only in women taking pills (oral contraceptives) b. A fatty streak is a small laceration in the intima of the aorta c. A fatty streak is thickening of the intima d. The lipids in the fatty streak are inside phagocytes e. The lipids in the fatty streak are free in the intima in the form of cholesterol crystals 11. A patient has died due to MI. In a histological examination of his left ventricular myocardium, the muscle fibers has presented necrosis and marked infiltration by PMNs. What is the age of the infarction? a. Less than 24 hours b. 2-3 days c. A week d. 3 weeks 12. Which area of the myocardium is most sensitive to ischemia? a. Apex b. Septum c. Internal third of the cardiac wall d.
