Optical Coherence Tomography (OCT) is an advanced intracoronary imaging modality that uses near-infrared light to generate high-resolution cross-sectional images of the coronary artery wall. Its detailed visualization, far superior to conventional angiography, makes OCT an essential tool for evaluating plaque morphology, stent apposition, thrombus burden and vessel response following percutaneous coronary intervention. As interventional cardiology increasingly relies on precision imaging, clinicians look to expert-led cardiology conference sessions to deepen understanding of image interpretation, procedural optimisation and technological advancements. Given its direct connection to coronary plaque imaging, this session explores how OCT improves diagnostic accuracy and guides procedural decisions across a broad range of clinical scenarios.

OCT enables clinicians to characterise plaques with exceptional clarity, distinguishing fibrous, lipid-rich and calcified components. Participants will learn how to identify vulnerable plaques, thin-cap fibroatheromas, erosions, healed lesions and microchannels. The session covers stent-evaluation parameters such as expansion, apposition, edge dissections, malapposition, tissue prolapse and neoatherosclerosis. These insights guide real-time adjustment of balloon sizing, lesion preparation and stent optimisation.

The programme reviews OCT acquisition techniques including contrast injection methods, pullback parameters, frame selection and artifact interpretation. Attendees will learn how to integrate OCT findings with angiography, IVUS and physiological indices such as FFR and IFR to improve decision-making and reduce complication rates.

OCT is also valuable for complex interventions such as bifurcation stenting, calcified lesion modification, left main evaluation and thrombus-rich lesions. Case studies demonstrate how OCT supports device selection, procedural planning and post-intervention assessment, improving long-term outcomes.

Future innovations include faster pullback systems, AI-assisted analysis, ultra-resolution imaging and integration with 3D vessel reconstruction. These developments promise enhanced precision and expanded use in interventional cardiology. This session provides a comprehensive view of how OCT transforms procedural quality, safety and patient outcomes.
