  1. Which cardiac valve separates the left atrium from the left ventricle?

    Answer: Mitral valve

    The mitral (bicuspid) valve is the atrioventricular valve located between the left atrium and left ventricle.

  2. The normal left ventricular ejection fraction (LVEF) range is approximately:

    Answer: 55–70%

    A normal LVEF is generally accepted as 55–70%, reflecting adequate systolic function of the left ventricle.

  3. Which structure separates the right and left atria?

    Answer: Interatrial septum

    The interatrial septum is the wall dividing the right atrium from the left atrium.

  4. The papillary muscles of the left ventricle attach to the mitral valve leaflets via which structures?

    Answer: Chordae tendineae

    Chordae tendineae are fibrous cords connecting papillary muscles to the mitral (and tricuspid) valve leaflets, preventing prolapse.

  5. Which coronary artery most commonly supplies the sinoatrial (SA) node?

    Answer: Right coronary artery

    In approximately 60% of individuals, the SA node is supplied by the right coronary artery (RCA).

  6. In echocardiography, the term 'end-diastole' refers to the phase when:

    Answer: The ventricle is maximally filled just before contraction

    End-diastole is the point just before ventricular contraction when ventricular volume is at its maximum.

  7. Which layer of the heart wall is responsible for the contractile function of the myocardium?

    Answer: Myocardium

    The myocardium is the muscular middle layer of the heart wall composed of cardiac muscle cells responsible for contraction.
