This clinical consensus document proposes standardized atrial segments for 3D imaging, electroanatomical mapping and computational modelling, based on anatomical, electrophysiological and clinical considerations, with precise definitions of regional borders allowing for reproducible and automated regionalization. 3D imaging and high-resolution electroanatomical mapping have become an integral part of cardiac electrophysiology and the management of patients with arrhythmias. However, to perform regional quantitative analyses and intra- and inter-individual, as well as cross-modality comparisons, a universal definition of atrial regions and their boundaries is required. While for the left ventricle there is already an established standardized regionalization (AHA 17-segment model), there is no such consensus for the atria. In a multi-disciplinary writing group consisting of cardiologists, cardiac electrophysiologists, cardiovascular imaging specialists, and anatomists as well as specialists in computational cardiac modelling from European Heart Rhythm Association and European Association of Cardiovascular Imaging, a standardized regionalization based on a 15-segment bi-atrial model was elaborated. This clinical consensus document will enable consistent regional analyses and homogeneous data acquisition across different centres and modalities, and may thus have a significant impact on atrial arrhythmia research and personalized treatment approaches based on individual arrhythmia patterns and phenotypes.
本临床共识文件基于解剖学、电生理学和临床考量，提出了用于三维成像、电解剖标测和计算建模的标准化心房节段，对区域边界进行了精确界定，以实现可重复和自动化的分区。三维成像和高分辨率电解剖标测已成为心脏电生理学和心律失常患者管理不可或缺的一部分。然而，为了进行区域定量分析以及个体内和个体间以及跨模态比较，需要对心房区域及其边界进行统一的定义。虽然左心室已有既定的标准化分区（美国心脏协会17节段模型），但心房尚无此类共识。由欧洲心律协会和欧洲心血管影像协会的心脏病学家、心脏电生理学家、心血管影像专家、解剖学家以及心脏计算建模专家组成的多学科写作小组，精心制定了基于15节段双心房模型的标准化分区。本临床共识文件将使不同中心和模态之间能够进行一致的区域分析和统一的数据采集，因此可能对心房颤动研究以及基于个体心律失常模式和表型的个性化治疗方法产生重大影响。
