Abstract

A system determines the individual Fractional Flow Reserve (FFR) values for the lesion of a multi-lesioned blood vessel during continuous blood flow therethrough, using a multi-lesion FFR processor (8). The individual FFR value for a lesion of interest can be determined by one of two different approaches. Both approaches require a hyperemic pressure measurement distal to the last lesion. However, one approach requires additional pressure measurements at rest, while the other requires additional hyperemic pressure measurements.
