Summary
This session highlights the utility of Near-Infrared Spectroscopy (NIRS) in guiding precise PCI beyond traditional angiographic assessment. It covers identification of vulnerable lipid-rich plaques, optimization of lesion preparation using atherectomy or lithotripsy when indicated, and improving stent deployment through integrated NIRS and IVUS guidance. Case presentations illustrate how this advanced imaging modality enhances procedural safety and effectiveness by targeting high-risk plaque features and tailoring interventional strategies.
Learning Objectives
- To identify vulnerable plaques: NIRS detects lipid-rich plaques that are invisible to angiography. This allows interventionalists to anticipate complications like distal embolisation or no-reflow and adjust their approach accordingly
- To optimise lesion preparation: when NIRS reveals high lipid burden or calcific nodules, operators can choose atherectomy, intravascular lithotripsy, or specialised balloons to modify the lesion before stenting
- To improve stent placement and expansion: NIRS-IVUS guidance ensures stents are deployed in stable segments, avoiding lipid-rich or heavily calcified areas that may compromise expansion or healing
