目的评价实时三维超声心动图测量老年患者左心室质量的准确性和重复性,并与磁共振对比.方法选取因各种不同原因进行心脏磁共振检查的老年患者31例,同时进行实时三维超声心动图检查.实时三维超声心动图检查采用Philips iE-33型超声心动图仪,左心室质量的分析通过TomTec工作站用人工描记法完成,并与磁共振所得结果相比较.结果实时三维超声心动图测量所得的左心室质量与磁共振测量结果比较,有良好的相关性.磁共振测量的左心室质量为74.4～208.1 g,平均(123.9±35.0)g.实时三维超声心动图测量的左心室质量为67.0～222.9 g,平均(128.6±37.9)g.二者所测结果相似(r=0.869,y=0.943 x+11.69,标准误为19.09 g),平均相差(4.7±37.7)g.在不同观察者间及观察者自身不同时间内测量的实时三维超声心动图结果显示良好的重复性.结论实时三维超声心动图可以用于测量老年患者的左心室质量.与磁共振比较,实时三维超声心动图测量老年患者的左心室质量有较好的准确性和重复性.

Objective To assess the accuracy and repeatability of real-time three-dimensional eehoeardiography (RT-3DE) for the measurements of left ventricular (LV) mass in elderly patients compared with magnetic resonance imaging (MRI).Methods A total of 31 patients (26 men) aged ≥60 years (72.1±6.6) years with various cardiovascular diseases were evaluated by MRI and RT- 3DE on the same day.RT-3DE was performed with a Philips iE-33 echocardiographic system, and LV mass was analyzed with the assistance of TomTec software.The results of LV mass 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 A good correlation was observed between RT-3DE data with manual border detection and MRI for LV mass (r=0.869, y=0.943 x+11.69, SE= 19.09 g, P< 0.01), with a mean difference of (4.7±37.7)g.The average LV mass was (123.9±35.0)g (74.4-208.1 g) evaluated by MRI, and was (128.6±37.9)g (67.0-222.9 g) evaluated by RT-3DE.There was good inter- or intra-observer correlation between RT-3DE by two sonographers for LV mass.Conclusions The assessment of LV mass from RT-3DE data is feasible in elderly patients.The mass can be determined with high accuracy and low interobserver variability in elderly patients with adequate eehocardiographic image quality.
