CV ASC Registry Education-Seq#7513-7533 (Native-Graft Vessel Instantaneous Wave-Free Ratio)

Video Transcription

Sequence 7513-7533, Native or Graphed Vessel Instantaneous Wave-Free Ratio, is indicating the lowest instantaneous wave-free ratio, also called IFR, of the native or graphed  vessel intra-procedure and prior to the intervention. The notes further clarify to accommodate for other assessment methods not collected specifically within the static dataset.  A CTFFR result, or a Resting Non-Hyperemic Flow Reserve Ratio, may also be coded in this field.  The instructions to code is to code 0 in this field to indicate ischemia was identified or an abnormal result.  As well, ischemia is defined as any one single of the following criteria. A CTFFR of 0.80 or less, the Abbott RFR of 0.89 or less, the PDPA of 0.91 or less, the  Boston Scientific DFR of 0.89 or less, the Boston Science DPR 0.89 or less, the Boston Scientific PDPA of 0.89 or less, the CathWorks FFR Angio 0.80 or less, the Medus Imaging  QFR of 0.89 or less, or physician documentation that the study results demonstrate ischemia. You will code 1 to indicate ischemia was not identified otherwise.  Continue to enter the actual IFR value documented if IFR was used.

Video Summary

The transcript discusses coding for ischemia based on the Instantaneous Wave-Free Ratio (IFR) in native or graphed vessels during medical procedures. It explains that a value of 0 should be coded if ischemia is present, defined by specific criteria such as CTFFR of 0.80 or less. A value of 1 should be coded if no ischemia is found. Additionally, if IFR was used, the actual IFR value should be recorded. The instructions also mention accomodating for other assessment methods and the range of ratios signifying abnormal results.
