A round swelling was on the substraction films of the right side of the heart taken during angiocardiographic examination of a patient with mitral valve disease; this suggested a mass attached to the inter-atrial septum, and prolapsing into the auricle of the right atrium. Initial diagnsosi was of atrial thrombosis, but this was disproved at operation. An aneurysm of the membrane of the fossa ovalis was found, being caused by overstretching of the auricle of the left atrium under the increased pressure of the valve defect. The aneurysm was resected and the septum simply repositioned as part of the mitral valve replacement. A search of the literature shows how rare this disorder is, and that it should be reclassified with the abnormalities of the inter-atrial septum which are found only rarely in cases of mitral valve disease.
在一名二尖瓣疾病患者进行心血管造影检查时所拍摄的心脏右侧减影片上，出现了一个圆形肿胀；这提示有一个附着于房间隔并突入右心房心耳的肿块。初步诊断为心房血栓形成，但手术时排除了这一诊断。发现了卵圆窝膜瘤，其病因是在瓣膜缺损压力增加的情况下左心房心耳过度伸展。切除了瘤体，并在二尖瓣置换术中简单地对间隔进行了重新定位。文献检索表明这种病症非常罕见，并且应将其与房间隔异常归为一类，而房间隔异常在二尖瓣疾病病例中仅很少见。
