摘　　要：肥厚型心肌病常继发心房颤动(简称房颤),导致临床结局显著变差,早期识别其房颤易感性、量化风险尤为重要。心脏磁共振成像集心脏解剖成像、功能成像于一体,可从左心房、左心室的结构、功能进行评价,可以对房颤发生风险进行早期预测、分层。本文回顾了心脏磁共振在肥厚型心肌病合并房颤时左心房、室结构、功能改变的相关进展,阐述了肥厚型心肌病发生房颤的相关机理,探讨了各种结构、功能参数在疾病发生发展过程中的应用价值及局限性,为制订更精准的诊断、治疗、管理策略提供可靠依据。Atrial fibrillation(AF)is often secondary to hypertrophic cardiomyopathy(HCM),which leads to significantly worse clinical ending.It is particularly important to identify the risks of AF and quantification.Cardiac magnetic resonance(CMR)imaging integrates cardiac anatomy and function,evaluates the structure and function of the left atrium and ventricle,and can predict and stratify the risk of AF early.We reviewed the relevant progress of CMR in the structure and function changes of the left atrium and ventricle in HCM complicated with AF,expounds the relevant mechanism of AF in hypertrophic cardiomyopathy,discussed the application value and limitations of various structural and functional parameters in the process of disease occurrence and development,to provide a reliable basis for formulating more accurate diagnosis,treatment and mangement strategies.
