Rheumatic Heart Disease Quiz

What is the primary function of the heart valves?

• To increase heart rate

• To separate blood chambers

• To facilitate smooth blood flow and prevent backflow

• To produce red blood cells

Which valves are predominantly affected in rheumatic heart disease (RHD)?

• Tricuspid and pulmonary valves

• Mitral and aortic valves

• Right atrial valves

• None of the above

What condition is caused by the body's autoimmune response to a Group A Streptococcal infection?

• Myocardial infarction

• Acute rheumatic fever (ARF)

• Aortic dissection

• Coronary artery disease

What occurs during valvular regurgitation?

• Blood flows smoothly through the valves

• Blood leaks backward due to incomplete closure of the valves

• Valves become narrowed and restrict blood flow

• Valves are completely healthy

When does valvular stenosis typically develop in the course of RHD?

• Early in the disease

• At the onset of symptoms

• Later in the disease process

• It does not develop in RHD

What is a potential consequence of blood pooling in the heart chambers?

• Increased oxygenation of blood

• Enhanced blood flow to the body

• Increased risk of clotting and stroke

• Improved valve function

How does severe RHD affect the heart muscle?

• It becomes more elastic and efficient

• It enlarges and thickens, losing elasticity

• It remains unchanged

• It develops new valves

In RHD, what may happen to the heart's ability to pump blood?

• It improves significantly

• It may lead to heart failure

• It remains the same

• It becomes more efficient

Which of the following is NOT a characteristic of the leaflets in RHD?

• They may become scarred and stiff

• They always regain their original shape

• They can become thickened and immobile

• They may not close completely

What is the role of the mitral and aortic valves in the heart?

• To regulate heartbeats

• To ensure blood flows in one direction

• To filter impurities from the blood

• To store oxygen for the body
