Optical coherence tomography: on the way to decipher the 'Rosetta stone'

Area of Science:

• Cardiovascular Imaging
• Biomedical Optics
• Interventional Cardiology

Background:

• Optical coherence tomography (OCT) is a light-based imaging technique providing high axial resolution, surpassing intravascular ultrasound.
• OCT enables detailed visualization of stent-tissue interactions at the individual strut level within coronary arteries.

Discussion:

• Key applications of OCT include assessing neointimal coverage over stent struts and identifying strut malapposition.
• These assessments are critical for understanding and improving outcomes following coronary stenting procedures.

Key Insights:

• OCT's high resolution provides unparalleled insights into the micro-architecture of stent implantation.
• Evaluating strut coverage and apposition is vital for predicting and preventing stent-related complications.

Outlook:

• Future research in OCT will likely focus on refining image analysis and expanding its role in guiding interventional cardiology.
• Addressing current limitations and exploring novel applications will further enhance OCT's clinical utility.
