FloWireÂ® Doppler Guide Wire image, courtesy Volcano Corporation. What is FFR? Fractional Flow Reserve, or FFR, is a guide wire-based procedure that can accurately measure blood pressure and flow through a specific part of the coronary artery. FFR is done through a standard diagnostic catheter at the time of a coronary angiogram (a.k.a. cardiac catheterization). The measurement of Fractional Flow Reserve has been shown useful in assessing whether or not to perform angioplasty or stenting on intermediate blockages. 1  The point of opening up narrowings or blockages in the coronary arteries is to increase blood flow to the heart.
