Patient receiving a standard of care FFR measurment in the cath lab setting.
Exclusion Criteria:
Hemodynamic Severity
Percentage of stenosis properly classified in terms of hemodynamic severity by iFR values ≤0.85 and ≥0.94. Hemodynamic severity will be established with an FFR value ≤ 0.80.
Time frame: at the time of study procedure- 1 day
Specificity
Minimum iFR exclusion ranges around iFR 0.89 in which iFR and FFR agreement is equal to or greater than 80% and 90%

Sensitivity
Minimum iFR exclusion ranges around iFR 0.89 in which iFR and FFR agreement is equal to or greater than 80% and 90%
