Jet/RVOT Ratio:
PR Severity:
jet width in PR
Formula:JET/RVOT Ratio = DAR / DRVOT

How to calculate Aortic Regurgitation Jet Width Ratio.

  1. Obtain a long axis view of the RVOT in CFD Mode. A good view is the RVIO view with CFD of the PR Jet. The RVOT and jet width can be accurately measured under a zoomed view.
