Hybrid iFR-FFR decision-making strategy: implications for enhancing universal adoption of physiology-guided coronary revascularisation
Why the study?
Does a hybrid iFR-FFR decision-making strategy reduce the need for vasodilator administration compared to an FFR-only strategy in patients undergoing coronary revascularisation?

Implication
May reduce vasodilator use during physiology-guided PCI; leaves open need for randomized outcome trials.
Key Points
- To evaluate whether a hybrid iFR-FFR decision-making strategy can reduce vasodilator administration while maintaining high diagnostic agreement with an FFR-only approach in guiding coronary revascularisation.
- Assessed a hybrid diagnostic pathway combining instantaneous wave-free ratio (iFR) and fractional flow reserve (FFR) to guide percutaneous coronary intervention (PCI).
- Compared vasodilator administration rates and diagnostic classification agreement of the hybrid strategy against a standard FFR-only strategy.
- The hybrid iFR-FFR strategy reduced the requirement for vasodilator administration by more than 50% compared with an FFR-only approach.
- High diagnostic classification agreement was preserved between the hybrid decision-making protocol and standard FFR-guided treatment decisions.
