摘要
左束支传导阻滞与心力衰竭、心肌重构及不良预后密切相关。与传统心电图相比,心脏磁共振可对心肌机械运动不同步性、心肌纤维化及血流动力学异常等进行多维度分析,为左束支传导阻滞的诊疗及预后评估提供影像学依据,优化心脏再同步化治疗的适应证筛选策略。本文就心脏磁共振在左束支传导阻滞疾病中的应用进展进行综述。
Left bundle branch block is associated with heart failure,myocardial remodeling and adverse clinical outcomes.Cardiac magnetic resonance imaging provides a comprehensive assessment of myocardial mechanical dyssynchrony,myocardial fibrosis and hemodynamic abnormalities.This multimodal imaging analysis enhances the diagnosis,treatment and prognosis evaluation of left bundle branch block and refines patient selection for cardiac resynchronization therapy.This review summarizes recent advances in the application of cardiac magnetic resonance in left bundle branch block disease.
