Abstract

Background: Slow flow caused by distal embolization during percutaneous coronary intervention (PCI) worsens outcomes. Near-infrared spectroscopy with intravascular ultrasound (NIRS-IVUS) can quantify the preoperative lipid burden. We investigated the utility of combining measurement of plaque size and lipid burden. Methods and Results: and 523, respectively. Either criterion identified all slow-flow cases (sensitivity 100%). Conclusions: enables simple and highly sensitive identification of lesions at risk of slow flow during PCI.
