[All AE-Adult-Echocardiography Questions]

The parasternal long axis view can be used to visualize which anatomical structure?

ACoronary sinus

BPulmonic valve

CEustachian valve

DLeft atrial appendage

Show Suggested Answer

Suggested Answer: A

The parasternal long axis (PLAX) view provides visualization of the left ventricle, left atrium, mitral and aortic valves, and importantly, the coronary sinus located posteriorly between the left atrium and left ventricle.

The pulmonic valve is best visualized in the parasternal short axis or suprasternal views. The eustachian valve is in the right atrium and visualized best in subcostal or apical views. The left atrial appendage is usually seen in transesophageal echocardiography.

This anatomical visualization is discussed in standard echocardiography textbooks and ASE imaging protocols12:ASE Imaging Guidelinesp.70-7516:Textbook of Clinical Echocardiography, 6ep.100-105.

I feel confident about the left atrial appendage. It’s a common focus.

But the coronary sinus is also a possibility, right?

I lean towards the pulmonic valve. It's often visualized there.

Wait, can you really see the Eustachian valve there?

Pulmonic valve, hands down. I mean, come on, that's Echocardiography 101. *laughs* Whoever wrote this question must have been having an off day.

Hmm, I'm not so sure about that. I feel like the parasternal long axis is more for looking at the coronary sinus. But hey, what do I know, I'm just guessing!

I think the left atrial appendage is the correct answer here. The parasternal long axis is great for getting a good look at that little structure.

The parasternal long axis view is definitely used to visualize the pulmonic valve. That's just basic cardiac anatomy knowledge.

I thought the Eustachian valve was something we could see in this view, but I might be mixing it up with another view.

I feel like the coronary sinus might be seen in this view too, but I don't know if it's the best answer here.

I remember practicing questions about the pulmonic valve in this view, but I can't recall if it's the primary structure visualized.

Ah yes, the parasternal long axis view - that's the one where you can see the left ventricle, aortic valve, and mitral valve. I'm pretty sure the answer is B) Pulmonic valve.

The parasternal long axis view, that's one of the standard echocardiogram views, right? I think it's used to see the left ventricle and mitral valve. I'm leaning towards D) Left atrial appendage.

Ugh, I'm drawing a blank on this one. The parasternal long axis view... is it for looking at the atria? I'm not sure, I'll have to guess and hope for the best.

The Eustachian valve? Really? That's in the right atrium, not something you'd see in the parasternal long axis view. Gotta love these trick questions!

Okay, the parasternal long axis view - I remember learning that this view lets you see the left ventricle and aortic valve. I'm pretty confident the answer is B) Pulmonic valve.

Hmm, the parasternal long axis view... I think that's used to look at the heart valves, but I'm not sure which one specifically. I'll have to think this through carefully.
