Impression:
Dry lungs, IVC with intramural tumor extending to the right atrium. LV OK. No flow on IVC or HV. Low stroke volume. Normal right kidney (some free fluid). Left kidney tumor
9/10
There is severe leg edema with low preload (low stroke volume, no lung edema) and no flow in the IVC
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!
