Chronic Total Occlusion Percutaneous Coronary Intervention (CTO PCI) is now performed with high success rates and acceptable complication rates.
We describe recent clinical and technological developments in CTO PCI from 2018 to 2020.
After publication of six randomized controlled trials, improving patient symptoms remains the principal indication for CTO PCI. Although good outcomes can be achieved with CTO PCI at experienced centers, success rates are significantly lower at less experienced centers, despite increased use in CTO crossing algorithms and development of novel and improved equipment and techniques.
慢性完全闭塞性冠状动脉介入治疗（CTO PCI）目前的成功率较高，并发症发生率也可接受。
我们描述了2018年至2020年CTO PCI领域近期的临床和技术进展。
六项随机对照试验发表后，改善患者症状仍是CTO PCI的主要指征。尽管在经验丰富的中心进行CTO PCI可取得良好效果，但在经验较少的中心，成功率显著较低，尽管CTO通过算法的应用有所增加，且新型改良设备和技术不断发展。
