Discuss ARDMS AE-Adult-Echocardiography Exam Topic 5 Question 15

Based on this video, what is the estimated right atrial pressure in millimeters of mercury (mmHg)?

C10

D15

Suggested Answer: C

Comprehensive and Detailed Explanation From Exact Extract:

The video shows a subcostal IVC view with measurement of IVC diameter and respiratory collapsibility. The IVC appears dilated (>2.1 cm) with less than 50% collapse on inspiration, suggesting elevated right atrial pressure (RAP).

According to ASE guidelines for noninvasive RAP estimation, an IVC diameter >2.1 cm with <50% collapsibility corresponds to an RAP of approximately 10 mmHg.

Lower RAP values correspond to smaller IVC and greater collapsibility. This is a standard measurement in adult echocardiography practice and ASE chamber quantification guidelines12:ASE Chamber Quantification Guidelinesp.80-8516:Textbook of Clinical Echocardiography, 6ep.115-120.

I feel like D) 15 is too much. It doesn’t match the visuals.

Rosalyn 2 months ago

I’m leaning towards C) 10. The measurements seem higher.

Raelene 2 months ago

I think it's B) 8. Looks reasonable from the video.

Glenn 2 months ago

I agree with you, Blair. A is too low for right atrial pressure.

Serina 2 months ago

Wait, 15 mmHg? That seems really high!

Tomas 2 months ago

I’m leaning towards C, 10 mmHg.

Blair 3 months ago

Definitely A, 3 mmHg seems too low.

Deeanna 3 months ago

I think it's option B, 8 mmHg.

I keep mixing up the values, but I think I saw a question where 15 mmHg was considered elevated. Could that be the answer here?

Barbra 3 months ago

I recall that normal values for right atrial pressure are usually lower, so maybe 3 mmHg is a possibility?

Shanda 3 months ago

I'm not entirely sure, but I feel like the right atrial pressure could be closer to 10 mmHg based on what we discussed in class.

Essie 4 months ago

I think I remember something about estimating right atrial pressure being around 8 mmHg in similar practice questions.
