Renal Venous Doppler 👇
According to doi.org/10.1161/JAHA.1…, Which curve color would best describe this patient's PH-related morbidity?
Poll and 🧵👇
1/6
Which curve in the Kaplan Meier Curve above best fits this particular patient?
2/6
The Renal Doppler shown 👆 looks like a biphasic pattern. This would mean the green curve 🟢
However there is a catch.....
3/6
This is not the correct location for evaluating renal congestion
It should be done in an intra-renal vein (arcuate, interlobar) and NOT the main renal vein!
The main renal vein displays more pulsatility than intra-renal veins.
This is an example from a healthy person:
4/6
In fact, this is the actual interlobar renal vein from the case discussed.
It is definitely NOT biphasic. I would call it pulsatile.
So the answer is the red 🔴 curve!
5/6
IRV Doppler can sometimes be hard to get and can easily be misinterpreted. This is why #VExUS exists!
In this case IVC was non plethoric, hepatic and portal veins had normal flow patterns (#VExUS = 0) arguing agains a "biphasic" intra-renal venous flow!

1⃣ Intra-Renal Doppler (IRVD) alterations are usually classified using morphological patterns (Continuous, Biphasic, Monophasic)
Looking at the relationship between Portal Vein Flow and IRVD you can notice the "Biphasic" pattern shows a very large spread of values! (2/6)
Switching to a classification based on interruption-time identified pts with a "Biphasic" pattern who were non-congested (short interruptions) or severely congested (long interruptions)
This classification has a much better agreement with Portal Vein Alterations! (3/6)
Normal HV is a mirror image of normal CVP waveform.
It usually has 4 waves:
2 antegrade (flow from liver to 🫀) waves (S and D)
2 retrograde (flow from 🫀 to liver) waves (A and V)
2/12
A frequent alteration in pts w severe PH is Severe Tricuspid Regurgitation
In severe TR, there is retrograde flow from the RV to the RA in systole. If the right atrium is not compliant, this flow reaches the HV and gives a reverse S wave!
