Revisiting Best Practices for an Accurate FFR and Non-Hyperemic Pressure Ratios (NHPR)

09/04/2018

“When is the right time to accept the fractional flow reserve (FFR) during the adenosine hyperemic recording?” I thought this issue had been settled a few years ago, but after speaking with Arnold, we thought we should revisit some of the...

iFR - The New Kid in Coronary Physiology. Results of 2 Outcome Trials: DEFINE-FLAIR and SWEDEHEART

04/30/2017

Morton J. Kern , MD, MSCAI, FACC, FAHA;

iFR is non-inferior to FFR and associated with fewer stents/CABG procedures. However, compared to FFR, there are no long-term outcome or independent ischemic testing validation data. Currently, FFR remains the comparative standard for iFR.

iFR is non-inferior to FFR and...
