Intravascular optical coherence tomography (OCT) is a recently developed technology that is becoming more and more increasingly available in the catheter laboratories. OCT is an easy and safe tool that can provide the operator with many valuable information aiding intervention and making the intervention safer and more predictable. OCT can guide all steps of intervention including target lesion assessment before intervention, stent selection, stent optimization, and post-stenting assessment. This review will summarize the role of OCT in guiding percutaneous coronary intervention.

“…OCT is also much more sensitive in detecting inadequate stent findings such as intrastent tissue protrusion, stent malapposition, stent edge dissection, and intrastent thrombus, which is helpful in optimizing stent implantation (11). Moreover, recently developed new stent optimization software such as OCT/angiography co-registration, three-dimensional (3D) navigation (Fig.…”

Optical coherence tomography (OCT) has emerged as a high-resolution (10-20μm), light-based, intravascular imaging technique capable of investigating detailed coronary plaque morphology. OCT is highly sensitive and specific for characterizing fibrous, fibrocalcific, and lipid-rich plaque. OCT is capable of discriminating 3 types of unstable plaque morphologies underlying coronary thrombosis such as plaque rupture, erosion, and calcified nodules. The high resolution of OCT has a potential to identify important features of vulnerable plaques such as thin-cap (<65μm thick) fibroatheroma, macrophages, vasa vasorums, cholesterol crystals, and micro- OCT technologyOCT uses near infrared light, at a wavelength of 1,250-1, 350 nm, to create images. The resolution of OCT is 10-20μm, which is approximately 10 times higher than that of IVUS.The imaging depth of OCT is 1.0-2.0 mm (depending on tissue type), which is approximately one-tenth of that of IVUS. The scan diameter of OCT is up to 10 mm. Imaging catheter of OCT has 2.5-2.8 Fr crossing profile. The imaging catheter is Annals of Nuclear Cardiology
