Intravascular Ultrasound (IVUS) / Optical Coherence Tomography (OCT) Imaging

Meaning:
Intravascular Ultrasound (IVUS) and Optical Coherence Tomography (OCT) are advanced imaging techniques used during coronary interventions to obtain detailed, real-time images from inside the blood vessels. These modalities provide precise information about vessel size, plaque composition, and stent positioning, enabling accurate assessment of coronary anatomy.

Causes:
IVUS and OCT imaging are required in complex coronary artery disease, unclear angiographic findings, heavily calcified lesions, left main or multivessel disease, and cases where precise stent sizing and placement are critical. They are especially valuable when standard angiography alone does not provide sufficient detail.

Treatments:
While IVUS and OCT are diagnostic tools, they play a key role in guiding treatment during PCI. Imaging helps optimize stent selection, ensure proper expansion and apposition, detect complications early, and improve overall procedural accuracy and outcomes.

Prevention:
Image-guided interventions help prevent complications such as stent under-expansion, restenosis, or thrombosis. Early and precise assessment of coronary disease using IVUS or OCT supports safer procedures and better long-term results in complex coronary care.
