Key result
IVUS and OCT outperform angiography alone for PCI guidance though neither imaging method proves superior.
Why the study?
Does intracoronary imaging (IVUS or OCT) improve clinical outcomes and stent optimization in patients undergoing PCI compared to angiography alone?
Does intracoronary imaging (IVUS or OCT) improve clinical outcomes and stent optimization in patients undergoing PCI compared to angiography alone?
Intracoronary imaging with IVUS or OCT provides superior PCI guidance and plaque evaluation compared to angiography alone, though neither modality is definitively superior to the other.

May support intracoronary imaging in complex PCI; leaves choice between IVUS and OCT unresolved.
Intracoronary imaging has brought new insight in the field of interventional cardiology. Intravascular ultrasound (IVUS) and optical coherence tomography (OCT) are the most commonly used imaging modalities. Regarding their technical characteristics IVUS and OCT have similarities as well as differences, a fact that could have significant clinical implications. Both techniques play an important role in percutaneous coronary intervention (PCI) guidance and demonstrated superiority compared to intravascular coronary angiography (ICA) guidance alone. Furthermore, their use can notably assist coronary plaque evaluation; both provide additional information of plaque characteristics, which can lead to a better understanding of the cause of an acute coronary syndrome (ACS) and better clinical outcomes. However, there is not enough clinical evidence for the superiority of one method compared to the other, something that is, also, reflected in the guidelines. In this review, we aim to compare role of IVUS and OCT in the different aspects of coronary artery disease (CAD), according to the latest scientific data. In addition, we present the future perspectives regarding the IVUS and OCT, with co-registration of the two methods or hybrid OCT-IVUS catheters.

Tsigkas et al. (2023) conducted a review in Coronary artery disease (CAD). Intracoronary imaging (IVUS and OCT) vs. Invasive coronary angiography (ICA) was evaluated. Intravascular ultrasound and optical coherence tomography provide superior percutaneous coronary intervention guidance compared to intravascular coronary angiography alone, though neither imaging method has proven definitive superiority over the other.
