Compared to the luminogram obtained by angiography, intravascular modalities produce cross-sectional images of coronary arteries with a far greater spatial resolution. It is capable of accurately determining the vessel size and plaque morphology. It also eliminates some disadvantages such as contrast streaming, foreshortening, vessel overlap, and angle dependency inherent to angiography. Currently, the development of its system and the visualization of coronary arteries has shown significant advancement. Of those, optical coherence tomography (OCT) makes it possible to obtain high-resolution images of intraluminal and transmural coronary structures leading to navigation of the treatment strategy before and after stent implantations. The aim of this review is to summarize the published data on the clinical utility of OCT, focusing on the use of OCT in interventional cardiology practice to optimize percutaneous coronary intervention.
与血管造影获得的发光图相比，血管内成像方式能产生具有更高空间分辨率的冠状动脉横截面图像。它能够准确确定血管大小和斑块形态。它还消除了血管造影固有的一些缺点，如造影剂流动、缩短、血管重叠和角度依赖性。目前，其系统的发展和冠状动脉的可视化已取得显著进展。其中，光学相干断层扫描（OCT）能够获得腔内和透壁冠状动脉结构的高分辨率图像，从而在支架植入前后指导治疗策略。本综述的目的是总结已发表的关于OCT临床应用的数据，重点关注OCT在介入心脏病学实践中优化经皮冠状动脉介入治疗的应用。
