Abstract

Introduction

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.

Methods and Results

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.

Conclusion

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.

巨大左心房附件动脉瘤伴持续性房性心动过速。

左心房附件动脉瘤（LAAA）是一种罕见的先天性心脏异常，涉及左心房附件（LAA）的进行性扩张，使患者容易出现严重的并发症，如心房性心动过速、危及生命的全身血栓栓塞和心功能障碍。方法和结果：我们描述了一例36岁女性因LAAA引起的不间断房性心动过速（AT），在尝试消融失败后手术成功终止了AT。LAA切除后AT终止。随访3个月无复发。结论：我们报告并讨论了罕见的由巨大LAAA引起的连续AT的处理方法，并在电解剖图上确定了定位。通过电视胸腔镜手术切除LAA是治疗LAAA AT的微创方法，被一致认为是安全和成功的。
