Optical Coherence Tomography (OCT) is an intravascular imaging modality that uses near-infrared light to provide high-definition, cross-sectional and three-dimensional images of the vessel microstructure during percutaneous coronary intervention (PCI).

Apr 26, 2022 · Optical coherence tomography (OCT) is a potent intravascular imaging modality that provides high‐resolution (10–20 μm) cross‐sectional images of coronary arteries and can be used for guiding percutaneous coronary interventions (PCIs).

Several validation studies have shown that OCT is more accurate in evaluating neointimal tissue after coronary stent implantation than intravascular ultrasound. Novel findings on OCT evaluation include the detection of strut coverage and the characterization of neointimal tissue in …

Jun 13, 2016 · Intravascular optical coherence tomography (OCT) can add value to angiography as a diagnostic and/or intervention tool for percutaneous coronary intervention (PCI) guidance. In diagnostic terms, it is essential to separate two very distinct populations: Stable coronary artery disease (CAD) and acute coronary syndromes (ACS).

Optical coherence tomography (OCT) provides similar information to IVUS (with some important differences), also potentially improving acute and long-term patient outcomes compared to angiography-guided PCI.

Jul 18, 2017 · Stent thrombosis (ST) is a serious complication following coronary stenting. Intravascular optical coherence tomography (OCT) may provide insights into mechanistic processes leading to ST. We performed a prospective, multicenter study to evaluate OCT findings in patients with ST.

Stent edge dissection is a predictor of stent thrombosis. OCT helps determine the presence or absence of stent edge dissection when angiography shows obscure findings (e.g., haziness, filling defect, or lumen narrowing).

Optical coherence tomography has emerged as a powerful tool for stent assessment, and in a short time, has become the modality of choice for studying stent and vascular interactions in vivo. In this review, we discuss qualitative and quantitative parameters used for stent assessment by …

Nov 3, 2022 · Common causes of in‐stent restenosis. A, Intravascular ultrasound (IVUS) and optical coherence tomography (OCT) cross‐sections of stent underexpansion. B, Significant plaque at the stent edge is seen on IVUS and OCT. C, Thrombus extends into the lumen on IVUS and OCT. D, Nonoverlapping stents.

Mar 31, 2025 · Researchers also observed a significant reduction in all-cause death, stent thrombosis, and target lesion and vessel revascularization among patients in whom intravascular imaging was used compared with angiography. Researchers further analyzed the two imaging modalities—IVUS and OCT—to determine whether one was more effective.
