Valvular Disease & Cardiomyopathies MCQs: practice questions

Sample Valvular Disease & Cardiomyopathies multiple-choice questions from Cardiovascular.

Infective endocarditis classically produces which characteristic lesion on affected valves?
- A. Small, sterile fibrin deposits mainly
- B. Large, friable vegetations with organisms and fibrin
- C. Pure calcific nodules with no vegetation
- D. Isolated leaflet thickening with no vegetation
- E. Complete leaflet destruction with no vegetative material
Which best explains the mechanism of syncope in severe aortic stenosis?
- A. Fixed output can't rise with exertional vasodilation
- B. Isolated arrhythmia unrelated to the valve lesion
- C. Direct cerebral embolism in most cases
- D. Complete absence of any hemodynamic explanation
- E. Isolated hypoglycemia
Which best distinguishes acute rheumatic fever from chronic rheumatic heart disease?
- A. The two terms describe comparable, simultaneous processes
- B. Chronic rheumatic heart disease commonly occurs without a preceding acute episode
- C. Acute rheumatic fever mainly affects the valves, rarely the myocardium
- D. Chronic rheumatic heart disease resolves largely without any lasting damage
- E. Acute: initial episode. Chronic: long-term scarring
Libman-Sacks endocarditis, associated with systemic lupus erythematosus, characteristically produces vegetations in which location?

- E. Both surfaces of the mitral leaflets
Endocarditis affecting the tricuspid valve is most classically associated with which risk factor?
- A. Isolated hypertension
- B. Advanced age alone, with no other risk factor
- C. Intravenous drug use
- D. Isolated hyperlipidemia
- E. Chronic kidney disease mainly
