Summary
Speaker: Dr Justin Davies, Imperial College London, UK
Justin Davies discusses the studies which have assessed the diagnostic performance of iFR (Instantaneous Wave-free Ratio) against FFR (Fractional Flow Reserve) against other gold standards including PET (Positron Emission Tomography), SPECT (Single-photon emission computed tomography), CFR (Coronary Flow Reserve), and HSR (Hyperaemic Stenosis Resistance).
Key learning points:
- 1. iFR and FFR has almost identical diagnostic accuracy
- 2. iFR is more closely related to flow than FFR
- 3. Clinical outcome studies like DEFINE-FLAIR and iFR SwedeHeart will further define the value of iFR
