OCT provides high-resolution (10-20 μm) imaging that effectively identifies vulnerable plaque features such as thin-cap fibroatheroma, macrophages, and cholesterol crystals, influencing PCI strategies for acute coronary syndrome.
Why the study?
Coronary angiography has limitations in assessing coronary plaque morphology, prompting the need to summarize the clinical impact and efficacy of optical coherence tomography.
How does optical coherence tomography (OCT) evaluate coronary plaques and atherosclerosis compared to other imaging modalities?

Overview
OCT plaque characterization should not yet change routine practice; leaves open whether it improves PCI outcomes beyond angiography.

Optical coherence tomography (OCT)
C
Comparator
Coronary angiography (CAG) and other intravascular imaging modalities

OCT is a high-resolution intravascular imaging tool that enhances the identification of vulnerable coronary plaques, thereby guiding medical and interventional management of acute coronary syndromes.
