The diagnostic value of ultrasonography in cases with incomplete endocardial cushion defect which has been verified by subsequent operation was studied. By the M-mode ultrasound examination an enlarged right ventricle, a narrowed outflow tract of left ventricular and an abnormal pattern of mitral value were shown. By the aid of 2-DE its diagnostic accuracy in this disease was almost 100%. Characteristically the ostium primum (atrial septal) defect and anterior mitral cleft were demonstrated. And by pulsed Doppler the signs of mitral regurgitation and the spectral features of atrial shunt could be found. Therefore, it is proposed that ultrasonographic examination could readily take the place of traumatic angiocardiography in the diagnosis of this disease.
研究了超声心动图对经后续手术证实的不完全性心内膜垫缺损病例的诊断价值。通过M型超声检查显示右心室增大、左心室流出道狭窄以及二尖瓣形态异常。借助二维超声心动图，其对该病的诊断准确率几乎达到100%。特征性地显示了原发孔（房间隔）缺损和二尖瓣前叶裂。通过脉冲多普勒可发现二尖瓣反流征象及心房分流的频谱特征。因此，建议超声心动图检查在该病诊断中可轻易取代创伤性心血管造影。
