Quantification of the change in shape of the dicrotic notches of so-called distal pressure pulses acquired distal to a lesioned section of a lesioned blood vessel relative to the dicrotic notches of so-called proximal pressure pulses acquired proximal thereto enable determination of values of hemodynamic parameters. The envisaged hemodynamic parameters can include so-called Pulse Transmission Coefficients, non-hyperemic substitutes to the clinically accepted Fractional Flow Reserve and Coronary Flow Reserve indices, and a RC time constant indicative of the health of the vascular bed fed by a lesioned blood vessel.
A system for determining the values of hemodynamic parameters for a lesioned blood vessel, the system comprising:
The system according to claim I wherein the hemodynamic parameter is a Pulse Transmission Coefficient index PTC(E) where
For use with intravascular pressure measurement apparatus capable of acquiring pressure measurements in a blood vessel during continuous blood flow therethrough, a processor capable of executing the following steps:
A method for determining the values of hemodynamic parameters for a lesioned blood vessel, the method comprising the steps of
