Fractional flow reserve (FFR) measured after percutaneous coronary intervention (PCI) has been identified as a surrogate marker for vessel related adverse events. FFR can be derived from standard coronary computed tomography angiography (CTA). Moreover, the FFR derived from coronary CTA (FFRCT ) Planner is a tool that simulates PCI providing modeled FFRCT values after stenosis opening.
Aim: To validate the accuracy of the FFRCT Planner in predicting FFR after PCI with invasive FFR as a reference standard.
