Left atrial appendage aneurysm (LAAA) is a rare congenital cardiac anomaly that involves the progressive dilatation of the left atrial appendage (LAA), predisposing the patient to serious complications such as atrial tachyarrhythmias, life-threatening systemic thromboembolism, and cardiac dysfunction.
We described a case of a 36-year-old woman with incessant atrial tachycardia (AT) originating from LAAA, which surgical intervention successfully terminated AT after attempted ablation failed. The AT terminated after the LAA was excised. There was no recurrence at the follow-up period of 3 months.
We present and discuss the management of rare incessant AT arising from giant LAAA where the localization was confirmed on electroanatomic mapping. LAA resection via video-assisted thoracoscopic surgery is minimally invasive approach to manage the LAAA AT, uniformly considered safe and successful.
左心耳动脉瘤（LAAA）是一种罕见的先天性心脏异常，涉及左心耳（LAA）的进行性扩张，使患者易发生严重并发症，如房性快速心律失常、危及生命的系统性血栓栓塞和心脏功能障碍。
我们描述了一例36岁女性患者，其持续性房性心动过速（AT）起源于LAAA，在尝试消融失败后，手术干预成功终止了AT。LAA切除后AT终止。在3个月的随访期内未复发。
我们展示并讨论了由巨大LAAA引起的罕见持续性AT的治疗，其定位通过电解剖标测得以确认。通过电视辅助胸腔镜手术切除LAA是治疗LAAA合并AT的微创方法，普遍认为安全且成功。
