OPTICAL COHERENCE TOMOGRAPHY-DEFINED PLAQUE VULNERABILITY IN RELATION TO FUNCTIONAL STENOSIS SEVERITY STRATIFIED BY FRACTIONAL FLOW RESERVE AND CONTRAST QUANTITATIVE FLOW RATIO

Recent studies have reported the association between plaque instability and physiological stenosis severity. Both functional stenosis severity and OCT-defined plaque instability are both related with adverse clinical outcomes. Measurement of the contrast-flow quantitative flow ratio (cQFR) is a
