Prospective (analysis of retrospective data), multi-center, observational, single-arm study. This structure was selected as the "worst case" due to the fact that it represents real life usage of invasive FFR measurement is performed mostly in "gray zone" cases, which are that their severity cannot be determined intuitively and based on the physician eyeball. By using real-world historical data of invasive FFR, the analysis of the obtained data can ensure that the study results are expected to include invasive FFR results that are in the grey zone, when invasive FFR is used in real life and represent the real expected use of the product. Furthermore, the analysis of the data obtained in the studies with these similar devices measuring FFR obtained from angiograms was actually performed in a retrospective manner. That is, although the angiographic images and pressure wire recordings were obtained in real-time, due to the need to mark the vessel in real-time and obtain specific projections during the procedure without which the FFR cannot be calculated, the primary endpoint (sensitivity and specificity) and accuracy were determined in all studies by a post-hoc review by a similar independent QCA core laboratory. The invasive FFR data, as well as the software generated FFR data were reviewed post-hoc by a core laboratory or even at the company.
