Prognosis of CT-derived Fractional Flow Reserve in the Prediction of Clinical Outcomes.

Purpose: To examine the prognostic implication of fractional flow reserve (FFR) derived from coronary CT (FFR) in routine clinical practice.

Materials And Methods: Patients referred for FFR analysis at a single center between October 2015 and June 2017 were retrospectively included and followed up for rates of invasive angiography and clinical events.
