Successful recanalization and percutaneous revascularization of coronary arteries with chronic total occlusion (CTO) is one of the "last frontiers" in coronary interventions. Conquering this objective may enable complete percutaneous revascularization in an increasing number of patients. Revascularization of CTOs carries multiple theoretical advantages such as improvement in wall motion abnormalities and left ventricular function, and ultimately, increased long-term survival. In the long term, when coronary disease progresses, having an open artery may increase the tolerance to future coronary events. The contemporary principles of the recanalization technique are reviewed.
成功开通和经皮冠状动脉介入治疗慢性完全闭塞病变（CTO）是冠状动脉介入治疗的“最后边界”之一。实现这一目标可能使越来越多的患者能够实现完全经皮血运重建。开通 CTO 具有多种理论优势，如改善心肌运动异常和左心室功能，最终提高长期生存率。从长远来看，当冠状动脉疾病进展时，开放的动脉可能会增加对未来冠状动脉事件的耐受能力。本文回顾了开通技术的当代原则。
