Hybrid use of intracoronary imaging and physiology to guide coronary revascularisation. Coronary angiography demonstrating intermediate distal left main coronary artery (LMCA) stenosis (A) with downstream severe disease in the mid left anterior descending (LAD) artery (B). Both fractional flow reserve (C) and resting full-cycle ratio (F) assessment confirm ischaemia within the LAD territory. Optical coherence tomography imaging demonstrates the minimal luminal area within the LMCA is 7.95 mm² (D), highlighting that targeted revascularisation of the proximal to mid LAD should be considered and precluding need for intervention of the LMCA.
