摘要
导管消融治疗已广泛应用于症状性、药物难治性心房颤动,但手术成功率仍相对较低,部分患者需要二次手术。利用成像技术了解心脏解剖、功能、组织特性等有助于提高消融手术的成功率。相比传统影像学方法,心脏核磁共振拥有无电离辐射性及对软组织高特异性的特点,可评估心房颤动术前肺静脉、左房结构以及术后损伤与瘢痕情况等,为导管消融的围术期、脑卒中预测、二次消融位点确定等提供有价值的证据。
Catheter ablation has been widely used for the treatment of symptomatic,drug-resistant atrial fibrillation. The success rate,however,is still relatively low,some patients may be obligated to have second procedure. Imaging techniques will help to improve the successful rate of catheter ablation by visualizing the cardiac anatomy,function,and its tissue characteristics. As compared with conventional imaging methods,the cardiac magnetic resonance have the features of non-ionizing radiation and unsurpassed soft tissue resolution,which assess information of pulmonary vein,left atrial structures before operative and damage,scar after procedure,providing valuable evidence for perioperative period of catheter ablation,predicting apoplexy,confirming precise site of the second procedure,and so on.
