Intracoronary Imaging for Percutaneous Coronary Intervention Guidance

Intracoronary imaging (ICI) is an important adjunct to invasive coronary angiography for the assessment of lesion morphology and guidance of percutaneous coronary intervention. Extensive data, including several randomized clinical trials and meta-analyses, support the use of ICI to improve clinical outcomes. Despite a modest increase in utilization, adoption remains limited, even in the setting of a robust evidence base and guideline recommendations. In this review, we provide a comprehensive overview of contemporary ICI modalities, including clinical indications, comparative advantages and limitations, and key supportive evidence. We also offer practical guidance on their use, procedural considerations, and address common pitfalls, as well as address the identification and clinical implications of high-risk "vulnerable" plaque features.
