Cardiac sources of embolic stroke include various abnormalities of the atrial septum. An atypical detachment of the septum primum was detected in two patients by dynamic three-dimensional echocardiography (DTDE). Between the septum primum and septum secundum a cavity with interatrial communication was detected. Within the cavity a turbulent color Doppler signal and an entry of the contrast agent EchovistR were detected. One of the patients suffered from repeated cerebrovascular events. This unusual defect of the atrial septum may be a potential source of embolism. Transesophageal echocardiography is considered the most sensitive method for the examination of the atrial septum. However, clear anatomic details could only be shown by DTDE.
栓塞性中风的心脏来源包括房间隔的各种异常。通过动态三维超声心动图（DTDE）在两名患者中检测到原发隔的非典型分离。在原发隔和继发隔之间检测到一个有房间交通的腔隙。在腔内检测到湍流的彩色多普勒信号以及造影剂EchovistR的进入。其中一名患者患有反复的脑血管事件。这种不寻常的房间隔缺损可能是潜在的栓子来源。经食管超声心动图被认为是检查房间隔最敏感的方法。然而，只有DTDE能显示清晰的解剖细节。
