Echocardiography Techniques II Exam 1 Practice

Question 1

Which of the following sets lists the causes of systolic flow disturbances?

Aortic stenosis, pulmonary stenosis, and mitral regurgitation Aortic stenosis, pulmonary stenosis, and mitral and tricuspid regurgitation Aortic stenosis, pulmonary stenosis, and mitral stenosis

Correct Answer:

Aortic stenosis, pulmonary stenosis, and mitral and tricuspid regurgitation

Explanation:

Systolic flow disturbances stem from issues that affect flow during ventricular contraction: either something obstructs the outflow tract or blood leaks backward through the atrioventricular valves. Aortic stenosis and pulmonary stenosis are obstructions to ejection during systole, making it harder for the ventricle to push blood out. Regurgitant lesions—mitral regurgitation and tricuspid regurgitation—cause backflow into the atria during systole when the valves fail to close properly. Mitral stenosis and tricuspid stenosis, by contrast, impede flow during diastole, not systole. Therefore, the complete set of causes of systolic flow disturbances includes both stenotic lesions (aortic and pulmonary) and regurgitant lesions (mitral and tricuspid), which is why the option listing all four is correct.

Question 2

Which statement best describes TAPSE measurement?

Measured in the apical four-chamber view using M-mode to assess longitudinal displacement of the tricuspid annulus toward the apex during systole Measured using tissue Doppler imaging at the tricuspid annulus Measured in the parasternal long-axis view to assess tricuspid annulus movement Measured in the apical four-chamber view using M-mode or 2D to assess longitudinal displacement of the tricuspid annulus toward the apex during systole

Correct Answer:

Measured in the apical four-chamber view using M-mode or 2D to assess longitudinal displacement of the tricuspid annulus toward the apex during systole

Explanation:

TAPSE measures how far the tricuspid annulus moves toward the apex during systole, reflecting RV longitudinal contraction. This is best assessed from the apical four-chamber view, using either M-mode through the lateral tricuspid annulus or 2D imaging to quantify the displacement. Tissue Doppler imaging at the annulus gives velocity (S'), not the total excursion, and the parasternal long-axis view isn’t ideal for visualizing the tricuspid annulus movement. So, the description that TAPSE is measured in the apical four-chamber view using M-mode or 2D to assess longitudinal displacement of the tricuspid annulus toward the apex during systole is the most accurate.

Question 3

What is the normal right atrial pressure?

5-10 mmHg 0-5 mmHg 10-15 mmHg 15-20 mmHg

Correct Answer:

0-5 mmHg

Explanation:

Normal right atrial pressure is about 0–5 mmHg. This reflects the preload of the right heart and corresponds to the central venous pressure in a healthy adult. In echocardiography, RAP is often estimated from the inferior vena cava: a small IVC with brisk inspiratory collapse supports a RAP in the 0–5 mmHg range, while a dilated IVC with little collapse suggests a higher RAP (often around 10–20 mmHg). Be aware that body position and ventilation can shift these values, so end-expiration in a resting, supine patient is the typical reference.

Question 4

What is a key advantage of 3D echocardiography for assessing the mitral valve morphology prior to surgery?

Not useful for valve repair planning. Replaces all 2D imaging. Allows detailed assessment of mitral valve apparatus, including annulus size, leaflet geometry, and billow; aids in planning repair strategy and device sizing without relying on geometric assumptions. Only used for research.

Correct Answer:

Allows detailed assessment of mitral valve apparatus, including annulus size, leaflet geometry, and billow; aids in planning repair strategy and device sizing without relying on geometric assumptions.

Explanation:

Three-dimensional echocardiography gives a true three-dimensional view of the mitral valve, allowing a complete and direct assessment of its anatomy before surgery. It provides en face and dynamic measurements of the annulus size and shape, leaflet geometry and billowing/tethering, and precise identification of which scallops are involved. Because you can quantify these features in their real spatial relationships, you can tailor the repair strategy and size devices without relying on geometric assumptions that are common with 2D reconstructions. This makes it a major advantage for preoperative planning, while it complements rather than replaces standard 2D imaging.

Question 5

In color Doppler imaging, which color represents flow away from the transducer in the aortic valve study?

Blue Red Green Yellow

Correct Answer:

Blue

Explanation:

Color Doppler encodes flow direction relative to the transducer. Flow toward the transducer is typically shown as red, while flow moving away is shown as blue. In the aortic valve study, the jet that moves from the left ventricle through the valve into the aorta is directed away from a standard transducer position, so it appears blue on the color map. Turbulent or very high-velocity areas can appear green or yellow depending on the palette, but the direction cue for flow away from the transducer is blue.
