Abstract: Introduction: Coronary physiology is recommended for guiding percutaneous coronary intervention (PCI). Previous cases have demonstrated changes in fractional flow reserve (FFR) in a donor collateral vessel after PCI to a chronic total occlusion (CTO). The behaviour of iFR in the context of CTO has not been described. Case summary: In this case we share the first case of the effect of CTO recanalisation on iFR in the donor artery, and show how iFR can reflect the amount of myocardium subtended by a stenosis. Discussion: iFR is able to incorporate the amount of subtended myocardium in its quantification of coronary stenosis severity.
