| 摘要: |
| 目的 通过总结分析双腔心室患儿的资料及回顾文献，探讨超声心动图在双腔心室诊断中的应用价值。方法 选取我院经超声心动图诊断为右室双腔心及左室双腔心患儿22例，应用二维超声心动图评估各室壁及腔室的组织结构，明确异常肌束的位置、形态、走行等，彩色多普勒及脉冲或连续多普勒探测异常血流的方向及速度，并结合其他辅助检查、手术结果及文献进行分析总结。结果 经超声心动图诊断为右室双腔心患儿共20例，所有患儿均合并室间隔缺损，其中9例同时合并其他先天性心脏病，最终经手术证实为右室双腔心患儿15例，余5例术中诊断为右室流出道狭窄。经超声心动图诊断为左室双腔心患儿共2例，经心脏MRI证实为左室双腔心患儿1例，另1例诊断为扩张型心肌病。结论 超声心动图在双腔心室诊断中具有重要的临床价值。 |

| Abstract: |
| Objective To investigate the value of echocardiography in the diagnosis of double chambered ventricle by analyzing the data of children with double chambered ventricle and reviewing the related literatures.Methods 22 children with double chambered ventricle diagnosed by echocardiography were included in this study. We retrospectively analyzed the cardiac structure and hemodynamic change in echocardiography. We used two-dimensional echocardiography to evaluate the structure of the ventricle in order to identify the position, shape of the abnormal muscle bundles. And we used Doppler echocardiography to detect the direction and velocity of abnormal blood flow. Together with other diagnostic examinations and surgical results，the characteristics of double chambered ventricle were analyzed.Results 20 patients with double chambered right ventricle were diagnosed by echocardiography. All of them had VSD and 9 patients were also had other congenital heart disease. 15 of the 20 cases were confirmed by surgery. And another 5 cases were diagnosed as right ventricular outflow tract stenosis in operation. 2 patients were diagnosed as double chambered left ventricle by echocardiography，of which one case confirmed by MRI, the other one was diagnosed as dilated cardiomyopathy.Conclusion Echocardiography plays an important role in the diagnosis of double chambered ventricle. |
