Abstract: Intravascular ultrasound (IVUS) provides valuable anatomic information about the coronary arterial lumen, wall, and plaques that cannot be assessed by coronary angiography alone. For over 2 decades, IVUS has been shown to be a helpful tool for identifying significant ischemia in angiographically intermediate left main (LM) or non-LM lesions by measuring the minimum luminal area. It can also guide percutaneous coronary intervention (PCI) in complex coronary lesions such as LM, bifurcation, chronic total occlusion, in-stent restenosis, and long or calcified lesions. In these complex lesions, IVUS can reduce stent thrombosi...
