Left atrial appendage aneurysm (LAAA) is a rare pathologic entity that can be congenital or, more frequently, acquired. Its complications include arrhythmias and thromboembolic events, palpitations, hiccups, chest pain, dyspnea, and myocardial infarction. LAAA can be isolated or associated with other congenital anomalies such as atrial septal defect, ventricular septal defect, anomalous renal artery, Noonan syndrome, and Hurler-Scheie syndrome. We report a rare case of giant LAA with intra-aneurysmal thrombus diagnosed by contrast-enhanced echocardiography.
左心耳动脉瘤（LAAA）是一种罕见的病理实体，可为先天性，但更常见的是后天获得性。其并发症包括心律失常和血栓栓塞事件、心悸、呃逆、胸痛、呼吸困难和心肌梗死。LAAA可以是孤立性的，也可与其他先天性异常相关，如房间隔缺损、室间隔缺损、肾动脉异常、努南综合征和胡勒尔-谢伊综合征。我们报告一例经对比增强超声心动图诊断为伴有动脉瘤内血栓形成的巨大左心耳的罕见病例。
