| 目的 应用实时三维超声心动图 (RT-3DE) 检测右室收缩功能,并与传统二维超声心动图对照,探讨该技术的可行性与准确性。 方法 使用RT-3DE系统采集32例健康志愿者的右室"金字塔"型数据库,结合容积分析软件,采用心尖八平面法勾勒右室舒张末期容积 (RVEDV) 和收缩末期容积 (RVESV),并计算右室每搏量 (RVSV) 和射血分数 (RVEF); 同时在M型超声心动图上测量右室游离壁三尖瓣环处的收缩期位移 (TASE)、二维超声心动图上勾画右室面积变化分数 (FAC),比较三维容积法测定的收缩指数与TASE、FAC间的相关性。 结果 RT-3DE测量的RVSV、RVEF均与TASE呈显著正相关 (r=0.90;r＝0.83);RVEF与FAC之间呈正相关 (r=0.63)。 结论 实时三维超声容积成像能快速简便、准确无创地确定右室容积,为临床早期评估右心收缩功能提供了有力手段,具有极其广阔的发展前景。 |

| Objective Aim of this study wasto evaluate right ventricular systolic function using indices derived from real-time three-dimensional echocardiography (RT-3DE), and to determine its clinical value. Methods Right ventricular "Full Volume" imaging was acquired by RT-3DE; Right ventricular end-diastolic volume (RVEDV) and right ventricular end-systolic volume (RVESV) were outlined using apical 8-plane method by the analysis software of RT-3DE offline. RVSV and RVEF were calculated . Meanwhile tricuspid annual systolic excursion (TASE) was measured by M-mode echocardiography; right ventricular fraction area change (FAC) was outlined by two-dimensional echocardiography. Results There were strong positive correlation of TASE to RVSV and to RVEF derived from RT-3DE (r=0.83; r=0.90). There was positive correlation between RVEF and FAC (r=0.63). Conclusion Real-time three-dimensional echocardiography could be used to rapidly, accurately, noninvasively determine right ventricular volume, RVSV and RVEF. It may allow early detection RV systolic function in clinical settings. |
