Diagnosis of sinus venosus atrial septal defect based on transthoracic color Doppler and two-dimensional echocardiography is often difficult. We recently experienced two cases of sinus venosus atrial septal defect which were correctly diagnosed using transesophageal color Doppler and two-dimensional echocardiography. Transthoracic color Doppler flow imaging did not demonstrate the atrial septal defect or the shunt flow across the defect in either case. Transesophageal two-dimensional echocardiography visualized a defect in the upper most portion of the interatrial septum in one case, and transesophageal color Doppler flow mapping detected a left-to-right shunt across the defect in both cases. Transesophageal color Doppler flow mapping also demonstrated the flow signal of the right upper pulmonary vein into the right atrium near its junction with the superior vena cava in each case. The diagnoses of sinus venosus atrial septal defect and combined partial anomalous pulmonary venous return were confirmed by surgery in both cases. Transesophageal color Doppler and two-dimensional echocardiography are very useful in diagnosing sinus venosus atrial septal defect and combined partial anomalous pulmonary venous return.
基于经胸彩色多普勒和二维超声心动图诊断静脉窦型房间隔缺损往往很困难。我们最近遇到两例静脉窦型房间隔缺损，通过经食管彩色多普勒和二维超声心动图得以正确诊断。在这两例中，经胸彩色多普勒血流成像均未显示房间隔缺损或穿过缺损的分流。经食管二维超声心动图在其中一例中显示房间隔最上部有缺损，经食管彩色多普勒血流图在两例中均检测到穿过缺损的左向右分流。经食管彩色多普勒血流图还显示了每例右上肺静脉在与上腔静脉交界处附近流入右心房的血流信号。两例均经手术证实为静脉窦型房间隔缺损合并部分性肺静脉异位引流。经食管彩色多普勒和二维超声心动图在诊断静脉窦型房间隔缺损合并部分性肺静脉异位引流方面非常有用。
