I just wanted to let you know that even though I'm looking quite old, I'm still a millenial.
So I just had a "New Year, New Me" moment and my resolution is to become a new and improved version of myself in a couple of weeks.
Don't worry, my wisdom won't change. You're still going to find the same useful information here. Stay tuned!
Regurgitant Flow Rate
to get a Regurgitant Flow Rate in Pulmonic Regurgitation.
Step 1: Obtain
a CFD of the PR Jet with a good PISA formation under
zoomed view. The Arch SAX view, DTG
or TG view of the PV LAX are good views for this calculation.
2: Measure the Diameter of the PISA radius.
The radius is from the center of the PISA formation,
typically from the center of the valve, to the first
aliasing velocity. If the PISA is small, try
slightly decreasing the aliasing velocity (VA) which
will increase the size of the PISA formation.
3: Obtain the angle of the PISA formation.
The angle is typically 180 degrees.
