In the treatment of stable coronary artery disease (CAD) the identification of patients who may gain the highest benefit from further invasive treatments is of pivotal importance for the healthcare system. In this setting, it has been established that an ischemia-guided revascularization strategy yields improved clinical outcomes in a cost-effective fashion compared with anatomy-guided revascularization alone. Invasive fractional flow reserve (FFR) is considered the gold standard, especially in the intermediate-range atherosclerotic lesions, for assessing lesion specific ischemia at the time of invasive coronary angiography and has now become the standard of reference for studies assessing the diagnostic performance of the various non-invasive stress tests. Coronary computed tomography angiography (cCTA) is an increasingly utilized non-invasive test that enables direct anatomical visualization of CAD in the epicardial coronary arteries with excellent sensitivity and negative predictive value. However, cCTA alone has poor specificity with FFR. With advances in computational fluid dynamics, it is possible to derive FFR from cCTA datasets improving its positive predictive value and specificity. The aim of this review is to summarize the technical aspects of FFR-CT, clinical evidence and limitations behind the novel technology, with a special focus on the recent PLATFORM Trial analyzing the effectiveness, clinical outcomes and resource utilization of FFR-CT. Finally, the future perspective of FFR-CT will be presented.
