摘　　要：心房颤动(AF)是成人最常见的心律失常,其发病机制尚未被完全阐明。左心房结构重塑和心肌纤维化是AF的诱发因素和维持因素,左心房纤维化会导致左心房心肌细胞电传导不均、减慢及左心房顺应性下降,增加永久性AF的发生及导管消融术后的复发率,故早期、快捷、准确评估AF患者左心房纤维化程度对AF患者治疗方案的选择和预后分析具有重要作用。大量研究表明,超声心动图在评估AF患者左心房纤维化上有一定的临床价值,本文旨在对其研究进展进行综述。Atrial fibrillation is the most common arrhythmia in adults.The pathogenesis of atrial fibrillation has not been fully elucidated.Left atrial structural remodeling and myocardial fibrosis are inducing and sustaining factors for atrial fibrillation.Left atrial fibrosis can cause uneven and slow electrical conduction of myocardial cells in the left atrium and reduce elasticity of the left atrium.This can increase the occurrence of permanent atrial fibrillation and recurrence rate after catheter ablation.Therefore,early,rapid and accurate assessment of the degree of left atrial fibrosis in patients with atrial fibrillation plays an important role in the decision-making of treatment and prediction of prognosis.Numerous studies have shown that echocardiography has some clinical value in the assessment of left atrial fibrosis in patients with atrial fibrillation.This article aims to review the research progress in this field.
