IVUS- Versus OCT-Guided Coronary Stent Implantation: a Comparison of Intravascular Imaging for Stent Optimization

Purpose of Review: Intravascular imaging provides improved diagnostic accuracy and optimization of percutaneous coronary interventions (PCI) compared with angiography alone. We review the latest literature on the predominant intravascular imaging modalities, intravascular ultrasound (IVUS), and optical coherence tomography (OCT). Recent Findings: A number of recently published clinical studies evaluating OCT and IVUS use have demonstrated improved procedural and clinical outcomes over angiography. Recent literature also reports on novel potential applications of these technologies. Summary: Intravascular imaging is an important diagnostic tool that augments angiography. IVUS has been the primary adjunctive intravascular imaging modality in interventional cardiology over the past three decades, while OCT is a newer modality of growing clinical importance. Both modalities augment angiography alone while having their own specific advantages and disadvantages. © 2018, Springer Science+Business Media, LLC, part of Springer Nature.
