Recently, other coronary physiologic parameters have been introduced: the "instantaneous wave-free ratio" (iFR). In this review, we will discuss the FFR, the iFR, and their use in the functional assessment of coronary stenosis in the cardiac catheterization laboratory. This review will cover ...
Instantaneous wave free ratio (iFR) is another physiological index which can be obtained at rest without hyperemic stimulation. iFR is conceptually different from FFR, leading to lively scientific debate about this index. In this review article, the concept, differences and similarities of FFR and ...

Another trial may offer a solution to better optimize PCI using a variant of FFR technology from Philips Healthcare called instant wave-free ratio (iFR). It co-registers the pressure drops with angiography so physician can identify precise locations causing ischemia, plan stent length and even pla...
Using recording methods we have employed for the last 20 + years, we have explored many analysis strategies. In this tutorial, we review what we have learned and what we think constitutes the most effective ways of capturing what the FFR can tell us. The tutorial covers FFR components (...
(Distal Evaluation of Functional Performance With Intravascular Sensors to Assess the Narrowing Effect: Guided Physiologic Stenting; NCT04451044), which is currently enrolling up to 3,200 patients to investigate whether physiology-guided PCI (using preinstantaneous and postinstantaneous wave-free ratio) ...
(hemodynamically significant) and the intermediate zone was defined as QFR 0.77–0.87 (non-conclusive). In addition, multiple limits (per 0.01 QFR-units) for normal (QFR-defer) and abnormal (QFR-treat) were simulated. The proportions of potential adenosine- and wire-free (FFR-free) procedures...
