ARDMS AE-Adult-Echocardiography Exam - Topic 1 Question 9 Discussion

Actual exam question for ARDMS's AE-Adult-Echocardiography exam
Question #: 9
Topic #: 1
[All AE-Adult-Echocardiography Questions]

Which flow component is indicated by the arrows on this image?

Show Suggested Answer Hide Answer
Suggested Answer: C

The Doppler waveform shows pulmonary vein flow with several components. The arrows point to small reversed flow spikes just after the atrial contraction wave, which corresponds to the atrial reversal (AR) flow component. Atrial reversal occurs as blood briefly flows backward into the pulmonary veins during atrial contraction.

Ventricular reversal is not typically seen in pulmonary veins. Diastolic flow reversal is abnormal and usually not part of normal pulmonary vein flow. Systolic forward flow is the major forward component during ventricular systole.

This interpretation is standard in ASE guidelines on diastolic function assessment and pulmonary vein Doppler evaluation12:ASE Diastolic Function Guidelinesp.85-9016:Textbook of Clinical Echocardiography, 6ep.130-135.

No way, it's systolic forward flow for sure!

I think it's actually atrial reversal.

Wait, is that really what it shows? I'm not convinced.

I feel like the answer could be atrial reversal, but I need to double-check my notes on flow patterns.

I remember something about ventricular reversal, but I can't recall if that's what this image shows.

This looks similar to a practice question we did on flow components, but I can't remember the exact details.

I think the arrows might indicate diastolic flow reversal, but I'm not entirely sure.
