Despite the detailed imaging information provided by optical coherence tomography (OCT) during percutaneous coronary intervention (PCI), clinical benefits of this imaging technique in this setting remain uncertain. The aim of the OCCUPI trial was to compare the clinical benefits of OCT-guided versus angiography-guided PCI for complex lesions, assessed as the rate of major adverse cardiac events at 1 year.

光学相干断层扫描引导与血管造影引导的经皮冠状动脉介入治疗复杂病变患者 (OCCUPI)：一项在韩国由研究者发起的、多中心、随机、开放标签的优越性试验


尽管光学相干断层扫描（OCT）在经皮冠状动脉介入治疗（PCI）期间提供了详细的成像信息，但这种成像技术在这种情况下的临床益处仍然不确定。 OCCUPI 试验的目的是比较 OCT 引导与血管造影引导 PCI 对于复杂病变的临床益处，以 1 年时主要不良心脏事件的发生率进行评估。
