However, the reproducibility of QFR is modest and there is high inter- and intra-observer variability even when fairly experienced but non-core lab operators (at least 150 QFR procedure experience) are performing the analysis. Although smaller studies have demonstrated that non-core analysis and even paramedical user analysis can have good correlation with FFR, the concern about the diagnostic performance of QFR in real-world clinical practice by inexperienced users remains.\n\nThe primary objective of \"Dedinje FFR\u002FQFR Registry\" is to determine the feasibility and diagnostic performance of QFR analysis by vendor-certified inexperienced medical users in a real-world setting using FFR as the gold standard. All patients \\>18 years old who present to the Institute for Cardiovascular Diseases \"Dedinje\" and undergo a planned or ad hoc FFR procedure will be asked to participate in the registry. FFR procedure is performed according to the standardized institutional protocol.
