房间隔动脉瘤是罕见的。它们与栓塞现象和房室口阻塞等并发症有关。我们描述了两名患者，一名成人和一名儿童，房间隔动脉瘤的诊断是由实时，二维超声心动图。房间隔动脉瘤表现为房间隔的薄的、局部的外凸，突出到右心房中，并且在心动周期期间其轮廓和大小显示出明显的变化。通过其相对较低的反射率、与房间隔的关系、心动周期内轮廓的显著变化以及外周静脉声学造影的特征性模式，可将其与其他心房内结构（如肿瘤、大咽鼓管瓣膜和心房内挡板）相鉴别。
Aneurysms of the interatrial septum are rare. They have been associated with complications such as embolic phenomena and atrioventricular orifice obstruction. We describe two patients, one adult and one child, with atrial septal aneurysms that were diagnosed by real-time, two-dimensional echocardiography. Atrial septal aneurysms appeared as thin, localized outpouchings of the atrial septum that protruded into the right atrium and showed marked variations in their contour and size during the cardiac cycle. They could be differentiated from other intra-atrial structures such as tumor mass, large eustachian valve and intra-atrial baffle by their relatively low reflectance, relationship to the atrial septum, considerable alterations in their outline during the cardiac cycle and characteristic patterns during peripheral venous contrast echocardiography.
