| 目的 观察实时三维超声心动图(RT-3DE)评估复杂型先天性心脏病左、右室收缩功能的可靠性。方法 复杂型先心病19例,男14例,女5例,年龄6个月~10岁,平均(2.65±2.46)岁。应用Philips Sonos 7500型超声仪(配X4矩阵探头)进行RT-3DE检查,结合TomTec"4D Cardio-view RT 1.2"容积分析软件采样8平面法测定心室的收缩末期和舒张末期容量,计算每搏量。测值分别与磁共振和M型超声心动图描记(ME)的二、三尖瓣瓣环收缩期位移进行比较。结果 RT-3DE测量的左室每搏量 和右室每搏量 与磁共振测量的LVSV(16.56±10.64)ml和RVSV(13.96±7.96)ml均存在显著正相关,r值分别为0.98和0.75,P均小于0.05。RT-3DE测定左室每搏量(12.67±10.10)ml和ME测定二尖瓣瓣环收缩期平均位移(8.17±1.92)mm之间的相关性显著,相关系数r＝0.86(P<0.001);RT-3DE测右室每搏量(11.83±12.02)ml和ME测定三尖瓣瓣环收缩期位移(11.04±3.06)mm两者亦存在显著正相关,相关系数r＝0.88(P<0.001)。结论 RT-3DE可准确测定复杂型先心病左、右室的每搏量,进行可靠评估左、右室的收缩功能。 |

| Objective To evaluate the reliability of real-time three-dimensional echocardiography (RT-3DE) in the systolic function assessment in complex congenital heart disease. Methods 19 consecutive pediatric patients with complex congenital heart diseases were recruited into the study. RT-3DE full volume imaging was performed using a commercial ultrasound scanner (SONOS 7500, Philips Medical Systems) equipped with a full-matrix array transducer (X4, 2-4 MHz). And the RT-3DE datasets were analyzed using a 4D Cardio-view RT 1.2 (TomTec Imaging Systems, Munich, Germany) to quantify the end-diastolic volume (EDV), the end-systolic volume (ESV) and the stroke volume (SV) of ventricle. The mitral and tricuspid annulus systolic excursion (MASE and TASE) were recorded by M-mode echocardiography (ME). Nine of all patients were examined by MRI simultaneously. Results LVSV and RVSV determined by RT-3DE were (15.90±10.62) ml and (12.42±4.69) ml respectively, which were shown good correlation with those determined by MRI . The r value was 0.98, and 0.75, respectively. LVSV and RVEV determined by RT-3DE were (12.67±10.10) ml and (11.83±12.02) ml respectively, which were well correlated with MASE (8.17±1.92)mm and TASE (11.04±l.06) mm determined with ME. The r value was 0.86 and 0.88 respectively. Conclusion RT-3DE can accurately quantify LVSV and RVSV for patient with complex heart disease, which can reflect the real situation of the systolic function of complex heart disease. |
