A Method for Estimating the Physiological Significance of Each of Serial Vascular Lesions
Abstract
The physiological severity of a stenosis is determined by its fractional flow reserve (FFR). Coronary arteriosclerosis is a diffuse disease and it is not uncommon for 2-3 serial lesions to be observed in the same vessel. Direct measurement of the physiological severity of each lesion is impossible due to the homodynamic interaction between them. The "true FFR" of a given lesion is defined as the FFR that would be measured if of other stenosis in the same vessel were absent.
