Angiography-Derived Quantitative Functional Assessment Versus Pressure-Derived FFR and IMR: The FAIR Study

Coronary Artery Disease Clinical Trial

Official title:
Diagnostic Performance of Angiography-Derived Quantitative Functional Assessment Compared to Pressure-Derived Fractional Flow Reserve and Index of Microcirculatory Resistance: The FAIR Study

Clinical Trial Summary

Coronary angiography-derived FFR assessment (AngioQFA) is a novel technique for physiological lesion assessment based on 3-dimensional (3D) quantitative coronary angiography (QCA) and virtual hyperemic flow derived from contrast frame count without drug-induced hyperemia. The goal of this prospective, multicenter trial is to compare the diagnostic performance of AngioQFA with invasive FFR as the reference standard. The secondary purpose is to compare the diagnostic accuracies of the computational fluid dynamics (CFD)-based index of microcirculatory resistance (IMR) using wire-based IMR as the reference standard.
