摘要

介绍。先天性左心耳发育不全并伴有异常位置的狭窄是一种极为罕见的疾病。我们报告一例发育不全的LAA伴二尖瓣狭窄在异常位置的病例,经食管超声心动图(TEE)误诊为腔内血栓。病例报告。一名43岁女性因用力时呼吸困难入院。TEE显示LAA存在严重的二尖瓣狭窄和血栓。病人接受体外循环心脏直视手术。术中左心房检查显示左心房发育不全,伴有狭窄和狭缝样口。也有一个错位的LAA被放置在瓣旁位置。LAA口不圆不宽,呈狭缝状。结论。作者认为,这种异常可能对轻度结构衰竭患者有一些生理后果。事实上,这种异常可能会加重心房壁和瓣膜的压力负担,从而加重结构失效的严重程度。

Incidental finding of a rare left atrial appendage anomaly: A case report
Introduction. Congenital hypoplasia of the left atrial appendage (LAA) with stenotic ostium in an abnormal position is an extremely rare entity. We report an exceptional case of hypoplastic LAA with ostial stenosis in an abnormal location in the patient with mitral valve stenosis that was mistaken in the transesophageal echocardiography (TEE) for an intraluminal thrombus. Case report. A 43-year-old woman was admitted to our center with dyspnea on exertion. TEE revealed the presence of severe mitral stenosis and clot in the LAA. The patient underwent open cardiac surgery by cardiopulmonary bypass. Intraoperative inspection of the left atrium revealed hypoplasia of the LAA with stenotic and slit-like ostium. There was also a malposition of the LAA that was placed in a paravalvular location. The ostium of the LAA was not round and wide but narrowed and slit-like. Conclusion. The authors believe that this anomaly may have some physiologic consequences in patients with mild structural failure. Indeed, this anomaly may aggravate the severity of structural failure by pressure burden on the atrial wall and valve.
