The diagnosis of atrial septal defect by transthoracic echocardiography remains difficult in a small subset of patients because of either suboptimal acoustic windows or unusual anatomy, for example, fenestrated defects. We report the case of a 55-year-old woman with a fenestrated atrial septal aneurysm that was incompletely visualized by transthoracic echocardiography. Subsequent transesophageal echocardiography demonstrated three defects within the atrial septal aneurysm with left-to-right shunting across each defect. Normal pulmonary venous connections were also defined. All echocardiographic findings were confirmed at surgery. This case demonstrates the additional diagnostic accuracy of transesophageal echocardiography for detecting disease of the atrial septum.
对于一小部分患者而言，经胸超声心动图诊断房间隔缺损仍存在困难，原因在于声学窗口欠佳或解剖结构异常，比如多孔型缺损。我们报告一例55岁女性患者，患有多孔型房间隔瘤，经胸超声心动图未能完全显示该病变。随后的经食管超声心动图显示房间隔瘤内有三处缺损，且每个缺损处均存在左向右分流。同时也明确了肺静脉连接正常。所有超声心动图检查结果均在手术中得到证实。该病例表明经食管超声心动图在检测房间隔疾病方面具有更高的诊断准确性。
