摘　　要：目的探讨实时三维超声(RT-3DE)在诊断心内膜垫缺损(ECD)中的应用。方法对32例ECD患者行常规二维超声与经胸RT-3DE检查,并与手术结果进行对照。结果全部病例RT-3DE图像均满意采集,经旋转切割等后处理,其显示立体的房间隔、室间隔缺损结构、房室瓣发育及血流情况较常规二维超声更加直观、全面和准确。与手术结果比较,常规二维超声误诊分型4例,术前漏诊10例二尖瓣隔叶裂。二维超声诊断二尖瓣裂的敏感性和特异性分别为92%、91%,RT-3DE诊断房室瓣或二尖瓣裂的敏感性和特异性均为100%,二者差异有统计学意义(P<0.05)。结论 RT-3DE较常规二维心动图可以更好地显示ECD的立体结构,对房室瓣的发育及血流情况有更全面及精确地诊断。Objective To explore the application of real - time three - dimensional echocardiography （ RT - 3DE） in diagnosis of endocardial cushion defect （ECD） . Methods Thirty - two patients with ECD were examined by conventional two - dimensional echocardiographic（2DE） and RT-3DE,the results were compared with surgery. Results All the patients were got satisfactory imaging, through revolving and cutting manipulate, the stereoscopical structure of atrial septum , interventricular septum, growth of atrioventricular septum and information of blood flow were displayed. RT- 3DE was more direct, overall, accurate than conventional 2DE. Compared with surgical results, there were 4 cases misdiagnosed by conventional 2DE. The sensitivity and specificity of 2DE in daignossis of mitral leaflet cleft were 92% and 91% , while the sensitivity and specificity of RT -3DE were 100%, 100%. There was significant difference between the two methods （P 〈 0.05 ）. Conclusion RT -3DE is more direct, overall, accurate than conventional 2DE to display and diagnose stereoscopical structure of atrioventricular septmn, growth of atrioventricular septum and information of blood flow.
