How To Ffr When The Ffr Wire Can T Pass Youtube Fractional flow reserve (ffr) wires are notoriously difficult to maneuver. we discuss a quick and simple technique to pass ffr wires across difficult lesion. To measure fractional flow reserve (ffr), the operator crosses the coronary stenosis with an ffr specific guide wire designed to record the coronary arterial pressure distal to the stenosis. the pressure transducer is located approximately 20 mm proximal to the distal tip of the wire, and it can be seen fluoroscopically.
Ffr Ifr And Other Resting Indices Pressure Wire Based Assessment Of The fractional flow reserve (ffr)—determined by comparing the aortic pressure (red) and the mean coronary artery pressure distal to the stenosis (yellow) after adenosine administration—is 0.84. thus, the stenosis is classified as not hemodynamically relevant, and consequently would not benefit from revascularization. Numerous multicenter, randomized trials have demonstrated improved clinical outcomes when measuring fractional flow reserve (ffr) with a coronary pressure wire to guide decisions regarding revascularization in the cardiac catheterization laboratory. 1–3 based on these data, guidelines now recommend the routine use of ffr in a variety of settings. 4 however, ffr remains underutilized for a.

A. a. a. fractional flow reserve (ffr) utilizes a specialized guide wire to measure blood pressure within a coronary artery. the original description of ffr required the induction of maximal hyperemia to achieve near linear correlation between coronary pressure and blood flow. 1 the most commonly used pharmacological agent is adenosine as an. Ffr and rfr for epicardial assessment. to determine the need for percutaneous coronary intervention, physiology indices such as fractional flow reserve (ffr) and resting full cycle ratio (rfr) are used to identify functionally significant epicardial coronary stenoses at stress or rest. 1. measure ffr and rfr with pressurewire™ x guidewire.
