应用二维多功能彩色多普勒超声心动图技术,探查22例单纯性小儿室间隔缺损(VSD)术后左心功能状况。其中9例同时进行了放射性核素心血池显像检查。结果发现:VSD术后左心舒张功能异常者8例(占36％),收缩功能异常者3例(占13.6％),两种显像技术测定左心室收缩、舒张功能的比较显示相关性良好。
Two-dimensional multi-function color Doppler echocardiography was used to investigate the left ventricular function after 22 cases of simple ventricular septal defect (VSD). Nine of them performed radionuclide blood pool imaging simultaneously. The results showed that there were 8 cases (36%) of left ventricular diastolic dysfunction after VSD and 3 cases (13.6%) of abnormal systolic dysfunction after VSD. The comparison of left ventricular systolic and diastolic function by two imaging techniques showed good correlation .
