AF is the most common arrhythmia in clinical practice. In addition to the severe effect on quality of life, patients with AF are at higher risk of stroke and mortality. Recent studies have suggested that atrial and ventricular substrate play a major role in the development and maintenance of AF. Cardiac MRI has emerged as a viable tool for interrogating the underlying substrate in AF patients. Its advantage includes localisation and quantification of structural remodelling. Cardiac MRI of the atrial substrate is not only a tool for management and treatment of arrhythmia, but also to individualise the prevention of stroke and major cardiovascular events. This article provides an overview of atrial imaging using cardiac MRI and its clinical implications in the AF population.
房颤是临床实践中最常见的心律失常。除了对生活质量有严重影响外，房颤患者发生中风和死亡的风险更高。最近的研究表明，心房和心室基质在房颤的发生和维持中起主要作用。心脏磁共振成像已成为一种可行的工具，用于探究房颤患者的潜在基质。其优势包括对结构重塑进行定位和定量。心房基质的心脏磁共振成像不仅是心律失常管理和治疗的工具，也是个体化预防中风和重大心血管事件的工具。本文概述了使用心脏磁共振成像进行心房成像及其在房颤人群中的临床意义。
