Optical coherence tomography imaging in acute coronary syndromes

Area of Science:

• Cardiovascular Imaging
• Medical Technology
• Pathology

Background:

• Optical coherence tomography (OCT) offers high-resolution, microscopic visualization of coronary plaques.
• OCT imaging is gaining interest for clinical and research applications in cardiology.

Purpose of the Study:

• To review the potential of OCT for in vivo identification of vulnerable coronary plaques.
• To highlight OCT's role in assessing features of vulnerable plaques relevant to acute coronary syndromes.

Main Methods:

• Review of recent studies utilizing OCT for coronary plaque assessment.
• Analysis of OCT's capability in visualizing plaque characteristics like rupture, erosion, and thrombus.

Main Results:

• OCT enables detailed assessment of coronary atherosclerotic plaques, including rupture, erosion, and thrombus.
• The technique can identify thin-cap fibroatheroma, vasa vasorum proliferation, and macrophage distribution around vulnerable plaques.

Conclusions:

• OCT is a valuable tool for cardiologists to understand thrombosis-prone vulnerable plaques and acute coronary syndromes.
• In vivo OCT imaging enhances the understanding of atherosclerotic lesion characteristics and their clinical implications.
