The effect of radiofrequency catheter ablation for atrial fibrillation (AF-ABL) has been established in the last decade and has become one of the major therapeutic options. As for the outcome of AF-ABL, there exit wide varieties in the success rate among the reports published so far, mainly due to the differences in the patient characteristics, ablation methods, and the observation manner/periods. In general, approximately 90% of success can be obtained in paroxysmal AF by a single procedure without the use of antiarrhythmic drugs, while it is around 60 to 80 % in persistent AF even with both repeat sessions and the use of drugs. The success rate has been shown to be constantly reduced during the long-term followup periods irrespective of the AF-type. Although AF-ABL has been shown to be effective to maintain sinus-rhythm compared to the pharmacological method, its impact on the prognosis has not been established yet.
在过去十年中，射频导管消融治疗心房颤动（房颤消融）的效果已得到确立，并已成为主要的治疗选择之一。至于房颤消融的结果，在目前已发表的报告中，成功率存在很大差异，这主要是由于患者特征、消融方法以及观察方式/观察期的不同。一般来说，阵发性房颤单次手术不使用抗心律失常药物时，成功率约为90%，而持续性房颤即使进行重复手术并使用药物，成功率也在60%至80%左右。长期随访期间，无论房颤类型如何，成功率都持续下降。虽然与药物治疗方法相比，房颤消融已被证明对维持窦性心律有效，但其对预后的影响尚未明确。
