| 探讨实时三维超声心动图技术诊断双腔右心室的价值。方法 以手术结果为金标准，对20例双腔右心室(DCRV)患儿运用二维和实时三维超声心动图进行剖析诊断，两种方法诊断结果与手术结果进行比较。结果 大动脉短轴立体切面和心尖四腔立体切面经剖析后能对双腔右心室的各种畸形进行准确诊断。以手术结果为金标准，实时三维超声心动图诊断正确率为100%，二维超声心动图诊断诊断正确率为90%，但两种方法没有统计学差异（P>0.05）。结论 大动脉短轴立体切面联合心尖四腔立体切面，可更直观的剖析结构畸形，提高双腔右心室诊断准确性,推荐实时三维超声心动图作为DCRV诊断的常规检测方法。 |

| Abstract: |
| Objective To evaluate values of real time three-dimensional echocardiography(RT-3DE) diagnostic technique in diagnosing double chambered right ventricle (DCRV)．Methods Compared with surgical operations，20 cases of children with double chambered right ventricle (DCRV) were diagnosed by two-dimensional and RT-3DE, two methods of diagnosis and surgical results were compared and comparing with the surgical results. Results Short artery 3D axis view and four chamber 3D view can diagnosis DCRV. As surgical operations gold standard，the accuracy of RT-3DE to diagnosis DCRV is 100%，the accuracy of 2DE to diagnosis DCRV is 90%，the accuracy of RT-3DE and 2DE were closely consistent(P>0.05)．Conclusions DCRV can be accurately diagnosed through Short artery 3D axis view combined with four-chamber 3D view．RT-3DE with topologic method can give more special information and it is more valuable in the diagnosis of DCRV than that of 2DE，recommended for RT-3DE as a conventional detection methods for the diagnosis of DCRV. |
