Abstract
Atrial fibrosis is an independent predictor of the recurrence of atrial fibrillation (AF) after catheter ablation. Low-voltage areas (LVA) measured during catheter ablation for AF are a commonly used surrogate for the presence of atrial fibrosis. LVA are associated with clinical outcomes and comorbidities and have links to triggering sites for AF. Several trials have shown promising data of targeting ablation in LVA, however the results have been mixed. This article will review the role of LVA in the prediction of adverse events in AF patients, including stroke, how to predict the presence of LVA, and the impact of LVA ablation on the recurrence of AF.
摘要
心房纤维化是导管消融术后心房颤动（AF）复发的独立预测因素。在AF导管消融期间测量的低电压区（LVA）是心房纤维化存在的常用替代指标。LVA与临床结局和合并症相关，并且与AF的触发部位有关。多项试验显示了针对LVA进行消融的有前景的数据，然而结果不一。本文将综述LVA在预测AF患者不良事件（包括卒中）中的作用、如何预测LVA的存在以及LVA消融对AF复发的影响。
