摘要
目的探讨超声心动图在双腔心室诊断中的应用价值。方法选取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、形态及走行等,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和手术结果进行分析总结。结果经超声心动图诊断为右室双腔心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2例,经心脏MRI证实为左室双腔心1例,另1例为扩张型心肌病。结论超声心动图在双腔心室诊断中具有重要的临床价值,可作为临床首选的检查方法。
Objective To investigate the value of echocardiography in the diagnosis of double chambered ventricle.Methods Twenty-two children with double chambered ventricle diagnosed by echocardiography were included in this study.The cardiac structure and hemodynamic changes were analyzed by echocardiography,the position and shape of abnormal muscle bundles were identified,the direction and velocity of abnormal blood flow were detected by color Doppler or continuous-wave Doppler,the characteristics of double chambered ventricle were analyzed combined with other diagnostic examinations and surgical results.Results Twenty cases with double chambered right ventricle were diagnosed by echocardiography,all of them complicated with ventricular septal defect,and 9 cases complicated with 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 by surgery.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.
