Around 1990, OCT was independently developed by two Japanese researchers, Naohiro Tanno of Yamagata University, Japan, and James G. Optical coherence tomography (OCT) is a method of obtaining tomographic images of a human organ based on the coherence of light. OCT is a novel, promising imaging modality with more in-depth assessments of its use, it may impact clinical outcomes in patients with symptomatic coronary artery disease. Recent OCT studies have provided insights into restenotic tissue characteristics DES restenotic morphologies differ from those with BMSs. While newer DESs promote more favorable vascular healing, the clinical implications remain unknown. Several OCT studies have demonstrated delayed neointimal coverage following drug-eluting stent (DES) implantation vs. At follow-up examinations after stent implantation, stent strut coverage and ISA can be assessed. During percutaneous coronary intervention (PCI), OCT can provide detailed information (dissection, tissue prolapse, thrombi, and incomplete stent apposition ). A recently developed frequency-domain OCT system has a faster frame rate and pullback speed, making the OCT procedure more user-friendly and not requiring proximal balloon occlusion. ![]() Because of the strong attenuation of light by blood, OCT systems required the removal of blood during OCT examinations. Based on polarization properties, OCT can differentiate tissue characteristics (fibrous, calcified, or lipid-rich plaque) and identify thin-cap fibroatheroma. ![]() Optical coherence tomography (OCT) is an optical analog of intravascular ultrasound (IVUS) that can be used to examine the coronary arteries and has 10-fold higher resolution than IVUS.
