Abstract
Open AccessIntravascular imaging has revolutionized the assessment and management of coronary artery disease, providing unparalleled insights into plaque morphology, lesion severity, and percutaneous coronary intervention (PCI) optimization. This comprehensive review explores the current landscape of intravascular imaging, detailing the principles and clinical utility of intravascular ultrasound (IVUS) and optical coherence tomography (OCT). We discuss the role of these technologies in various clinical scenarios, ranging from stable coronary artery disease to acute coronary syndromes, emphasizing their ability to refine diagnostic accuracy and therapeutic decision-making. A key focus is placed on their application in identifying vulnerable plaques, a critical step in preventing adverse cardiovascular events. Furthermore, we highlight the role of intravascular imaging in guiding PCI, improving stent deployment, and reducing procedural complications. Finally, we explore emerging imaging modalities and technological advancements poised to further enhance coronary assessment, including hybrid imaging techniques. In addition to established modalities, this review examines emerging imaging technologies and the growing integration of artificial intelligence (AI) and hybrid imaging systems, which hold promise for automated plaque characterization, improved reproducibility, and enhanced decision support during PCI. By summarizing the latest evidence and future directions, this review aims to provide a comprehensive reference for clinicians and researchers seeking to optimize the use of intravascular imaging in contemporary cardiovascular practice.
