Abstract:
iFR‐guided revascularization is non‐inferior to FFR at 1 year, despite being discordant with FFR in 20% of cases. In 587 patients, we studied predictive factors for this discordance. Stenosis location involving the left main or proximal left anterior descending coronary, more severe stenosis, younger age and slower heart rate were significant predictors of a negative discordant iFR (FFR+/iFR‐). Lack of use of a beta‐blocker, older age, and less severe stenosis were significant predictors of a positive discordant iFR (FFR‐/iFR+). Clinical, angiographic and hemodynamic conditions during iFR acquisition influence concordance with FFR and must be taken into account when interpreting iFR. image
