目的探讨三维超声心动图(3DE)在小儿圆锥动脉干畸形(CTD)病理形态学诊断中的应用价值。方法用HPSonos5500型彩色超声心动图仪和TomTecEcho-view4.2对210例0~15岁CTD患儿进行二维超声心动图(2DE)和3DE检查,并以心导管造影和手术诊断为标准,用5剖切面10剖视面三维超声剖视诊断方案和VanPraagh先天性心脏病顺序分段诊断步骤对CTD作3DE剖视诊断,结果与2DE对比。结果房、室间隔左、右心观(L1a、L2a)、心脏四腔观(Ha、Hb)、瓣膜俯视及仰视观(S1a、S2a)等剖视面对CTD有诊断价值,在心室构型,心室大动脉连接,室间隔缺损具体位置、形态及其与大动脉相互关系等方面能较2DE提供更多空间信息。在已手术的147例中,补充2DE诊断18例(12.2%),纠正2DE诊断10例(6.8%)。结论3DE可对CTD作出较准确的三维病理形态学诊断,能基本满足CTD3DE剖视诊断要求。
Objective To investigate the value of three-dimensional echocardiography (3DE) in pathological diagnosis of congenital heart disease (CTD) in children. Methods Two-dimensional echocardiography (2DE) and 3DE were performed in 210 children aged 0-15 years with HPSonos5500 color echocardiography and TomTec Echo-view4.2. Cardiac catheterization and surgical diagnosis were used as standard. 5 Section 10 Section 3D cross-sectional ultrasound diagnosis of diagnostic programs and VanPraagh congenital heart disease step by step sequence diagnostic procedures for 3DE CTD diagnosis, the results compared with 2DE. Results The findings of atrial and ventricular septum left and right views (L1a and L2a), heart and chest views (Ha, Hb), valvular top and bottom views (S1a and S2a) , Ventricular aortic connection, ventricular septal defect specific location, morphology and its relationship with the aorta and other aspects than 2DE to provide more space information. Of 147 patients who had surgery, 18 (12.2%) were diagnosed with 2DE and 10 (6.8%) corrected 2DE. Conclusion 3DE can make a more accurate 3D pathological diagnosis of CTD and can basically meet the diagnostic requirements of CTD3DE.
