The left atrial appendage (LAA) has recently been recognized as a potential source of arrhythmia in patients undergoing repeat ablation procedures for atrial fibrillation (AF). In this case report we describe sustained fibrillation contained entirely within the LAA, that continued even after electrical isolation of the LAA was performed. This case supports the concept that in selected patients with AF, catheter ablation strategies may need to incorporate LAA isolation to minimize recurrence.
左心耳（LAA）最近被认为是接受房颤（AF）重复消融手术患者心律失常的一个潜在来源。在本病例报告中，我们描述了一种完全局限于左心耳内的持续性颤动，即使在对左心耳进行电隔离后仍持续存在。该病例支持这样一种观点，即在特定的房颤患者中，导管消融策略可能需要纳入左心耳隔离以尽量减少复发。
