Article Title: Coronary CT Angiography Derived Fractional Flow Reserve: The Game Changer in Noninvasive Testing.
Abstract: PURPOSE OF REVIEW: To summarize the scientific basis of CT derived fractional flow reserve (FFR) and present an updated review on the evidence from clinical trials and real-world observational data RECENT FINDINGS: In prospective multicenter studies of patients with stable coronary artery disease (CAD), FFR showed high diagnostic performance. More recently, FFR has advanced to the realm of clinical utility and real-world clinical practice with emerging data showing that FFR when compared to standard care is efficient in safely reducing downstream utilization of invasive coronary angiography (ICA), and costs, as well as improving the diagnostic yield of ICA. Moreover, FFR may broaden applicability of frontline coronary CTA testing to patients with high pre-test risk of CAD. Introducing FFR into clinical practice has the potential to significantly improve the management of patients with stable CAD. The optimal FFR testing interpretation strategy, as well as the relative cost-efficiency of FFR against standard noninvasive functional testing, need further investigation.
