Valvular Heart Disease Overview
1. Common causes of acquired valvular heart disease:
o A) Rheumatic heart disease
o B) Infective endocarditis
o C) Degenerative changes (e.g., calcification)
o D) Trauma
Correct Answer: All of the above (A, B, C, D)
2. What has contributed to the decrease in the incidence of valvular heart diseases
(VHD)?
o A) Increased prevalence of rheumatic fever
o B) Advanced technology and antibiotics
o C) Higher rates of heart surgery
o D) Decreased awareness of heart health
Correct Answer: B) Advanced technology and antibiotics
, 3. Spectral Doppler: flow traveling towards the transducer appears above or below the
baseline?
o A) Above the baseline
o B) Below the baseline
Correct Answer: A) Above the baseline
4. Explain the significance of observing mitral regurgitation below the Doppler
baseline during systole. What does this indicate about the flow of blood?
o A) It indicates normal flow during diastole.
o B) It suggests retrograde flow from the left ventricle to the left atrium.
o C) It shows that there is no regurgitation present.
o D) It indicates forward flow from the left atrium to the left ventricle.
Correct Answer: B) It suggests retrograde flow from the left ventricle to the left
atrium.
5. What happens to the chamber proximal to the stenotic valve?
o A) Hypertrophy of ventricular walls
o B) Increased afterload
o C) Stenotic valve drives the pressure up
o D) All of the above
Correct Answer: D) All of the above
6. Explain how commissural fusion contributes to the doming of valve leaflets in
valvular heart disease.
o A) It restricts leaflet movement during diastole.
o B) It causes increased pressure on the leaflets.
o C) It leads to abnormal blood flow patterns.
o D) It prevents the leaflets from closing properly.
Correct Answer: D) It prevents the leaflets from closing properly.
