Cardiovascular disease remains a leading cause of global mortality, largely driven by the rupture or erosion of atherosclerotic plaques. For decades, two-dimensional luminal angiography has been the gold standard in interventional cardiology.

Cardiovascular disease remains a leading cause of global mortality, largely driven by the rupture or erosion of atherosclerotic plaques. For decades, two-dimensional luminal angiography has been the gold standard in interventional cardiology. However, it falls short in characterizing the complex biology of mural structures and vulnerable plaques. Welcome to 'Optical and Hybrid Intravascular Imaging for Cardiovascular Plaque Assessment,' a comprehensive course designed to bridge the gap between traditional anatomical assessment and cutting-edge plaque characterization. In this advanced program, you will explore the fundamental biological drivers of atherosclerosis and discover why high-resolution intravascular imaging is revolutionizing cardiovascular research and clinical workflows. Dive deep into the principles and applications of Optical Coherence Tomography (OCT), Near-Infrared Spectroscopy (NIRS), Fluorescence-Lifetime Imaging (FLIm), and Intravascular Photoacoustic (IVPA) imaging. Beyond the hardware, this course tackles the critical intersection of computational analysis and artificial intelligence, teaching you how automated semantic segmentation and machine learning are accelerating real-time cath lab decision-making. You will also learn to navigate the complex translation barriers—from regulatory hurdles and interoperability challenges to histology validation and evidence thresholds—that dictate the clinical adoption of novel diagnostic tools. Whether you are looking to optimize percutaneous coronary intervention (PCI) planning or pioneer the next generation of hybrid imaging catheters, this course provides the multidisciplinary expertise needed to advance cardiovascular care.

            <p>Cardiovascular disease management relies heavily on the precise characterization of atherosclerotic plaque biology. Traditional two-dimensional luminology, such as standalone angiography, is inherently limited in its capacity to visualize complex mural structures and identify the pathological mechanisms driving plaque rupture and erosion. To overcome these diagnostic limitations, the integration of high-resolution optical and hybrid intravascular imaging has emerged as a critical advancement in both clinical workflows and cardiovascular research. This comprehensive program elucidates the foundational morphology of expansive vascular remodeling, lipid core formation, and localized inflammation, establishing the clinical imperative for advanced plaque characterization beyond simple anatomical assessment.</p>

<p>Throughout this curriculum, participants will systematically analyze the optical principles, procedural mechanics, and diagnostic yields of Optical Coherence Tomography (OCT) alongside emerging hybrid modalities. The course provides an in-depth examination of Near-Infrared Spectroscopy (NIRS), Fluorescence-Lifetime Imaging (FLIm), near-infrared fluorescence (NIRF) molecular imaging, and Intravascular Photoacoustic (IVPA) imaging. By differentiating the unique endogenous contrasts and depth penetration capabilities of these systems, professionals will learn to accurately identify fibrous, lipid-rich, calcified, and thrombotic components. This technical mastery is directly applied to clinical interpretation, enabling precise risk stratification, the differentiation of active culprit versus high-risk nonculprit lesions, and the optimization of percutaneous coronary intervention (PCI) guidance and safety protocols.</p>

<p>Beyond image acquisition and clinical prognosis, the successful implementation of novel diagnostic tools requires navigating complex translational and methodological landscapes. The final segments of this course critically evaluate the integration of artificial intelligence and automated semantic segmentation in expediting real-time decision-making, while emphasizing the necessity of rigorous histological co-registration to establish accurate reference standards. By addressing frequently underestimated translation barriers—including regulatory approval pathways, interoperability challenges, and health economic assessments—this program equips interventional cardiologists, imaging scientists, biomedical engineers, and regulatory stakeholders with a robust evidence framework to critically evaluate and drive the future adoption of cardiovascular imaging technologies.</p>
