COMMENTARY: Broadening the Applications of Fractional Flow Reserve

08/01/2008

The concept of fractional flow reserve (FFR) was introduced by Pijls et al in his publication in 1993.1 This concept uses pressure measurement as a surrogate for flow, in a state where resistance is minimal and constant, a state of maximal...
