[Role of optical coherence tomography to optimize complex coronary interventions]

Area of Science:

• Cardiovascular Imaging
• Medical Technology
• Interventional Cardiology

Background:

• Coronary artery disease (CAD) diagnosis and treatment require detailed imaging.
• Percutaneous coronary interventions (PCI) benefit from precise anatomical and pathological information.
• Stent implantation and failure analysis necessitate high-resolution visualization.

Purpose of the Study:

• To highlight the capabilities of Optical Coherence Tomography (OCT) in cardiovascular imaging.
• To demonstrate OCT's role in diagnosing and managing coronary artery disease and PCI.
• To underscore OCT's utility in evaluating stent implantation and failure.

Main Methods:

• Utilizes a catheter-based system employing light and fiberoptics for high-resolution imaging.
• Applies advanced algorithms for lumen measurement and angiographic co-registration.
• Analyzes atherosclerotic plaque characteristics and calcium deposition with microscopic detail.

Main Results:

• OCT accurately maps coronary artery disease extension and plaque types.
• It differentiates atherosclerotic from non-atherosclerotic causes of acute coronary syndromes.
• OCT precisely detects calcium and measures parameters influencing stent expansion, optimizing PCI outcomes.

Conclusions:

• OCT is a valuable tool for diagnosing CAD and guiding complex PCI.
• It accurately assesses plaque and calcium, crucial for successful stent deployment.
• OCT aids in differentiating mechanical from biological causes of stent failure, enabling tailored treatments.
