Brief Summary

Optical coherence tomography (OCT) provides valuable information to guide percutaneous coronary intervention (PCI) in acute coronary syndrome (ACS) regarding lesion preparation, stent sizing, and stent optimization.

Detailed Description

OCT can be used in acute coronary syndrome (ACS). ACS has more complex culprit lesion morphologies and larger extent of coronary atherosclerosis compared with stable coronary artery disease. The detailed vascular information obtained by OCT may impact PCI in ACS, and which may improve acute results and late outcomes of PCI. Stent expansion immediately after PCI is a strong predictor of late outcomes of PCI, and it is associated with late clinical outcomes in many previous trials.
