心房颤动经导管射频消融术后复发的预测因素

心房颤动（AF）是临床上最常见的心律失常，具有较高的致残率和死亡率，需尽早干预治疗。经导管射频消融（RFA）治疗AF已在世界范围内推广，逐渐成为AF的一线治疗方法。大量的研究表明，RFA治疗AF具有较大的优越性，避免了药物复律引起的副作用，总成功率达73.3％，但仍有近26．1％的复发率。因此，降低RFA治疗AF的复发率及寻找RFA术后复发的预测因素对临床医师识别患者、选择合适的治疗策略具有重要意义。本文从基础指标、临床特征、病理解剖因素、临床生化指标、消融术式及术后管理等方面综述了AF经RFA治疗后复发的预测因素。

Recurrent predictors of atrial fibrillation after radio-frequency catheter ablation treatment

Atrial fibrillation （AF） is the most common type of arrhythmia clinically, which has high morbidity and mortality, and needs early intervention. Radio-frequency catheter ablation （RFA） has been widely used to treat AF throughout the world, with the trend to become first-line treatment of AF. Numerous studies indicate that RFA has great advantages in treating AF and is free of side effects of drug-induced cardioversion. There is a total success rate of 73.3%, but still nearly 26.1% recurrence rate exists clinically. To reduce recurrence rate and＇investigate the recurrent predictors are significant for clinicians to identify patients and choose appropriate treatment strategy. In this paper, we reviewed the predictors of recurrence following RFA of AF in the following aspects： the basic indicators, clinical characteristics, pathological anatomy factors, clinical biochemical index, ablation procedures, postoperative management, and so on.
