Pssst! It's me, the website.

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!

How to get a Regurgitant Fraction in Pulmonic Regurgitation.
Step 1:  Obtain a CFD of the PR Jet with a good PISA formation under zoomed view.  The Arch SAX, DTG PVLAX, or TG PVLAX views should provide a good view of the pulmonary valve.  The RVIO view can also be used, although Vmax cannot be obtained with this view.
Step 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.
Step 3: Obtain a VTI of the Regurgitant Jet by CWD.    From the flow profile the Vmax and the VTI of the regurgitant jet can be obtained by tracing the diastolic flow profile.
Step 4: Obtain the angle of the PISA formation. The angle is typically 180 degrees.
