During percutaneous coronary intervention (PCI), intravascular ultrasound (IVUS) provides anatomic information for the coronary artery lumen, wall, and plaques, which can help the accurate evaluation of the lesion with vessel sizing. Moreover, post-PCI stent underexpansion, malapposition, or edge dissections can be detected for stent optimisation, resulting in improved clinical outcomes. Recently, much evidence demonstrating the clinical usefulness of IVUS has become available, particularly for complex lesions, such as left main disease, chronic total occlusions, and diffuse long lesions.
