A 65-year-old man was referred to our hospital with persistent atrial fibrillation (AF). Before the ablation procedure, 3-dimensional computed tomography revealed a left atrial anomalous muscular band connecting the posterior side of the left atrial roof and the right edge of the fossa ovalis. During the first ablation procedure, the band interfered with the manipulation of the catheter, resulting in only the left pulmonary vein (PV) being isolated. However, AF recurred. During the second procedure, careful catheter manipulation permitted complete right PV isolation, after which, the patient has not had AF recurrence for more than 3 years.
一名65岁男性因持续性心房颤动（AF）转诊至我院。在消融手术前，三维计算机断层扫描显示一条左心房异常肌束连接左心房顶部后侧和卵圆窝右缘。在首次消融手术期间，该肌束妨碍了导管操作，仅隔离了左肺静脉（PV）。然而，房颤复发。在第二次手术中，通过仔细的导管操作实现了右肺静脉的完全隔离，此后，患者已超过3年未出现房颤复发。
