From QFR to OFR: Intracoronary OCT derived FFR for Assessment of Stenosis Severity

European Bifurcation Club 2019, EBC 2019 - Barcelona, Spain NEWS 2 From QFR to OFR: Intracoronary OCT-derived FFR for assessment of stenosis severity Author: Shengxian Tu, MD, PhD, Shanghai Jiao Tong University, China Limitations of angiography-based FFR Angiographic image overlap and significant foreshortening Post-PCI optimization: stent mal-apposition/under-expansion OFR Analysis Steps Automatic OCT lumen contour delineation and 3D reconstruction Automatic reconstruction of cut- planes at the side branches ostia Compute OFR using the QFR algorithm SUMMARY OFR (OCT-based FFR) provides lesion morphology and physiological assessment in a single OCT pullback. Compared with FFR, OFR showed good diagnostic accuracy, excellent reproducibility and short analysis time. OFR had substantially better diagnostic accuracy than OCT-MLA. OFR is promising for use in the cath lab for PCI optimization.
