摘要
目的观察实时三维超声心动图(RT3DE)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PhilipsSonos7500型超声仪(配X4矩阵探头)进行RT3DE检查,结合TomTec“4DCardioviewRT1.2”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RT3DE测量的左室每搏量[LVSV,(15.9±10.62)ml]和右室每搏量[RVSV,(12.42±4.69)ml]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。RT3DE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);RT3DE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RT3DE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 [male 14, female 5, aged （2.65±2.46） years] 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 fullmatrix 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 [（16.56±10. 64）ml and （13.96±7.96） ml]. 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）ram and TASE （11.04±1. 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.
