E is for Entrance
- Entrance and Effusion
- Effusion (tamponade)
- Backs up in IVC
- Sonographic equivalent of jugular venous distension (JVD)
Effusion with IVC dilation

Narration
So here is another example of 2 of the Es in this case entrance, the IVC you can see is dilated and non-collapsable, you can also see what’s called 'smoke' in there, which is sort of the echogenicity of the blood running into the heart which happens in a low flow state. The other thing you can see as shown in the diagram with the arrow is a fairly large pericardial effusion at the inferior pericardium just over the liver. The combination of a dilated IVC with an effusion is indicative of tamponade physiology. The IVC is the equivalent of the physical exam finding of jugular venous distention. Again, when the fluid is around the heart it prevents filling of the heart, it'll back up into the venous system, whether that is the IVC or the jugular vein.
