Advanced Aortic Valve Quiz

Q1. Which aortic valve cusp is associated with the right coronary artery?

• Left coronary cusp
• Pulmonary cusp
• Right coronary cusp
• Noncoronary cusp

Q2. Which cusp is associated with the left coronary artery origin?

• Left coronary cusp
• Septal cusp
• Right coronary cusp
• Noncoronary cusp

Q3. What is the function of the aortic sinuses during valve closure?

• Help fill and close the cusps
• Open the mitral valve
• Anchor chordae tendineae
• Contract the cusps actively

Q4. Coronary arterial filling occurs predominantly during which phase?

• Isovolumetric contraction only
• Ventricular diastole
• Peak ventricular systole
• Atrial systole only

Q5. Which valve lies in close fibrous continuity with the aortic valve?

• Tricuspid valve
• Mitral valve
• Valve of inferior vena cava
• Pulmonary valve

Q6. Which heart sound includes closure of the aortic valve?

• Second heart sound
• Fourth heart sound
• First heart sound
• Third heart sound

Q7. Which event immediately precedes normal aortic valve opening?

• Left ventricular pressure exceeds aortic pressure
• Aortic pressure exceeds ventricular pressure
• Mitral valve opens
• Atrial pressure falls below venous pressure

Q8. Why does the aortic valve not require papillary muscles?

• It is attached to the atrial wall
• Its cusps function through pressure gradients
• It remains open during diastole
• Its cusps contain skeletal muscle

Q9. A congenital bicuspid aortic valve has how many functional cusps?

• Two
• Three
• One
• Four

Q10. Which statement best describes normal aortic valve function?

• It opens through papillary muscle contraction
• It permits systolic ejection and prevents diastolic backflow
• It directs blood from the right ventricle into the aorta
• It permits diastolic ejection and prevents atrial backflow
