摘　　要：冠状动脉慢性完全闭塞(CTO)为冠状动脉造影的常见发现,发生率在15%~25%。CTO经皮冠状动脉介入治疗(PCI)仍然是冠状动脉粥样硬化性心脏病介入治疗领域的热点与难点,适当的术前评估和患者选择有助于术者采取更加合理的治疗策略,提高PCI成功率。心脏磁共振成像(CMR)作为复杂心血管疾病评估的重要非侵入性成像方法,对于准确判断CTO再血管化手术的适应证具有重要指导意义。本文从CMR的优势及局限性、CMR与CTO患者心肌存活、CTO-PCI及预后4个方面对CMR在CTO诊疗中的应用与进展进行综述,以期为CTO患者的正确治疗策略提供参考。Chronic total occlusion(CTO)of the coronary artery is a common finding in coronary angiography,with an incidence rate of 15%to 25%.percutaneous coronary intervention(PCI)for CTO remains a hotspot and a challenge in the field of coronary heart disease intervention.Proper preoperative evaluation and patient selection can help the surgeon adopt a more reasonable treatment strategy and improve the success rate of PCI.Cardiac magnetic resonance imaging(CMR)is an important non-invasive imaging method for evaluating complex cardiovascular diseases.It plays an important role in guiding the selection of patients suitable for revascularization surgery for CTO.This review summarizes the application and progress of CMR in the diagnosis and treatment of CTO from the advantages and limitations of CMR,the relationship between CMR and myocardial viability in CTO patients,CTO-PCI and prognosis.It is hoped that this review can provide reference for the correct treatment strategy of CTO patients.
