【摘要】 冠状动脉慢性完全闭塞(CTO)病变在经皮冠状动脉介入治疗(PCI)患者中非常普遍，其手术难度大，风险高，目前的临床终点获益尚不明确。本文总结了CTO-PCI随机对照临床试验和观察性研究，介绍了近些年最新的PCI器械和管理策略，以期为CTO-PCI提供全新的理论和实践依据。更多还原

【Abstract】 Chronic total occlusion(CTO) of the coronary artery is a common occurrence among patients undergoing percutaneous coronary intervention(PCI), a procedure known for its difficulty and associated risks. However, the precise clinical endpoint benefit of CTO-PCI remains unclear. In this review, we aim to provide a comprehensive summary of recent randomized controlled clinical trials(RCTs) and observational studies pertaining to CTO-PCI. Additionally, we introduced the latest PCI devices and management strategies developed in recent years. By consolidating existing evidence and advancements, this review seeks to offer a new theoretical and practical foundation for enhancing CTO-PCI procedures and outcomes.更多还原
