IS147: Coronary Pressure Measurement and Fractional Flow Reserve
Nico H.J. Pijls, M.D., Ph.D.

Figure 3. To measure fractional flow reserve (FFR) in the catheterization laboratory, a pressure wire is placed across the stenosis and an adequate hyperemic stimulus administered. One recording of the proximal and distal pressure allows for calculating the FFR. (Pijls 2000)
