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.
冠状动脉内成像为介入心脏病学领域带来了新的见解。血管内超声（IVUS）和光学相干断层扫描（OCT）是最常用的成像方式。就其技术特性而言，IVUS和OCT既有相似之处，也有不同之处，这一事实可能具有重大的临床意义。这两种技术在经皮冠状动脉介入治疗（PCI）指导中都发挥着重要作用，并且与单独的血管内冠状动脉造影（ICA）指导相比显示出优势。此外，它们的使用可以显著辅助冠状动脉斑块评估；两者都提供了斑块特征的额外信息，这有助于更好地理解急性冠状动脉综合征（ACS）的病因并改善临床结果。然而，没有足够的临床证据表明一种方法优于另一种方法，这一点也在指南中有所体现。在本综述中，我们旨在根据最新科学数据比较IVUS和OCT在冠状动脉疾病（CAD）不同方面的作用。此外，我们还介绍了IVUS和OCT的未来前景，包括两种方法的联合注册或混合OCT-IVUS导管。
