Optical Coherence Tomography (OCT)

Optical Coherence Tomography (OCT) is one of the most advanced imaging technologies used in interventional cardiology today. It provides microscopic-level clarity of the coronary arteries, offering far greater detail than traditional angiography or even Intravascular Ultrasound (IVUS). Using near-infrared light, OCT generates high-resolution, cross-sectional images of the inside of coronary arteries — allowing cardiologists to visualize the vessel wall structure, plaque characteristics, and stent placement with unmatched precision.

Dr. Arun Mohanty uses OCT technology to achieve exceptional accuracy in diagnosing and treating complex coronary artery diseases, ensuring safer and more effective outcomes for his patients.

How OCT Works

OCT uses a special optical fiber catheter that emits near-infrared light into the coronary artery. As the light reflects off different tissue layers, it is captured to create detailed, real-time images of the artery’s interior. These images have a resolution of about 10–20 microns, providing a microscopic view that helps identify even the smallest abnormalities inside the vessel.

During a coronary angioplasty or stent placement, OCT imaging is performed to:

• Assess the severity and nature of plaque buildup (fatty or calcified).
• Determine precise vessel dimensions for optimal stent selection.
• Guide accurate stent deployment and ensure full expansion.
• Evaluate stent apposition and tissue coverage after placement.
• Detect micro-tears, thrombus, or complications that may not be visible on angiography.

Advantages of OCT Over Traditional Imaging

OCT offers a much higher resolution compared to angiography and IVUS, making it the gold standard for precision-guided coronary interventions. Its key advantages include:

• Microscopic Detail: Provides unparalleled visualization of artery walls and stents.
• Accurate Diagnosis: Helps distinguish between different plaque types and detect early disease.
• Improved Stent Optimization: Ensures proper expansion and positioning for long-term results.
• Enhanced Safety: Reduces the risk of complications during and after angioplasty.
• Better Clinical Decisions: Empowers the cardiologist with precise data for personalized treatment planning.

When OCT is Recommended

OCT imaging is particularly beneficial in cases where:

• The coronary anatomy is complex or unclear on angiography.
• There is uncertainty about plaque composition or lesion severity.
• The patient has previously placed stents and requires evaluation for restenosis.
• Precise stent deployment and optimization are crucial for successful outcomes.
