Combining Optical Coherence Tomography and Fractional Flow Reserve for Decision Making in Percutaneous Coronary Intervention: Insights From the FUSION Study

Fractional flow reserve and OCT provide distinct yet complementary information that significantly impacts decision making during PCI. Specifically, FFR informs revascularization decision making, while OCT plays a crucial role in device sizing. Combining anatomical, morphological, and physiological variables in a single modality may enhance decision making and reduce resource utilization.
