Clinical Data
See the data behind FFR, DFR and Pd/Pa

A PCI Guidance portfolio backed by data you can trust

  • Overview on coronary physiology.
  • FFR calculates Pd/Pa during maximal hyperemia.
  • DFR™ calculates a diastolic portion of the cardiac cycle at rest.
  • Pd/Pa calculates the entire cardiac cycle at rest.


What is Fractional Flow Reserve (FFR)?


A strong body of long-term clinical outcomes supports FFR to identify ischemia-producing lesions and shows improved outcomes over angio-guided procedures alone.

An FFR cutoff of ≤0.80 is most commonly used in clinical studies. To expect the outcomes of the major clinical studies (FAME, FAME II, etc.) 0.80 with maximum hyperemia should be used. The AUC Guidelines reflect the FAME cutoff of 0.80.
