目的 评价实时三维超声心动图(RT3D)测量老年患者左心室容量的准确性和重复性. 方法 选取因各种不同原因进行心脏磁共振成像(MRI)检查的老年患者31例,同时进行RT3D检查.RT3D检查采用Philips iE-33型超声心动图仪,左心室容量和左心室功能的分析通过TomTec工作站用人工描记法完成,并与MRI结果比较. 结果 MRI测量的左心室舒张末期容量(LVEDV)为(139.1±40.8)ml,左心室收缩末期容量(LVESV)为(77.8±41.7)ml,左心室射血分数(LVEF)为(46.9±17.4)％.RT3D测量的LVEDV为(119.5±37.7) ml,LVESV为(65.5±36.1)ml,LVEF为(47.9±14.3)％.与MRI比较,RT3D低估LVEDV(P＜0.01,r=0.79,y=0.73 x+17.8,SEE=23.5 ml),两者平均相差(-19.6±25.6)ml.RT3D同时低估LVESV,两者比较差异有统计学意义(P＜0.01,r=0.89,y=0.77 x+ 5.6,SEE=16.8 ml),两者平均相差(-12.3±19.1)m[.LVEF值两种测量方法比较,差异无统计学意义(P＞0.05,r=0.91,y=0.75 x+13,SEE=5.61％),平均相差(1.1±7.4)％.不同观察者采用RT3D测量的左心室容量有良好的重复性. 结论 与MRI比较,RT3D测量老年患者左心室容量、LVEF有较好的准确性和重复性.

Objective To assess the left ventricular(LV) volumes and function acquired by realtime (RT) three-dimensional echocardiography (3DE) versus magnetic resonance imaging (MRI) in elderly patients.Methods A total of 31 patients aged≥60 years [mean (72.1±6.6) years] with various cardiovascular diseases were evaluated by MRI versus RT-3DE on the same day.RT-3DE was performed with a Philips iE-33 echocardiographic system,and LV volumes and function were analyzed with the assistance of TomTec software.The results of LV volumes and function obtained by manual tracing were compared with Signa 1.5-T MRI data.The acquisition of RT-3DE datasets was feasible in all 31 patients.Results The average MRI-detected LV end diastolic volume (LVEDV) was (139.1 ±40.8) ml,LV end systolic volume (LVESV) was (77.8±41.7)ml,LV ejection fraction (LVEF) was (47.9±14.3)％.The average RT-3DE-detected LVEDV was (119.5±37.7) ml,LVESV was (65.5±36.1) ml,LVEF was (47.9± 14.3)％.Compared with MRI values,LVEDV was underestimated by RT-3DE (P＜0.01,r=0.79,y=0.73 x+17.8,SEE=23.5 ml),with a mean difference of (-19.6±25.6)ml; LVESV was also underestimated by RT-3DE (P＜0.01,r=0.89,y =0.77 x+ 5.6,SEE=16.8 ml),with a mean difference of(-12.3± 19.1)ml.Ejection fraction determined by MRI was the same as that by RT-3DE (P＞0.05,r=0.91,y=0.75 x+ 13,SEE=5.61％),with a mean difference of (1.1±7.4) ％.There was good interobserver reproducibility in LV volume detected by RT-3D.Conclusions Compared with MRI,RT-3DE has more accuracy and repeatability in assessment of LV volume and ejection fraction in elderly patients.
