目的：探讨实时三维超声心动图（RT-3DE）检测室壁瘤患者左心室容积和收缩功能的可行性和准确性。方法应用RT-3DE及左心室造影分别测量21例室壁瘤患者的左心室舒张末容积（LVEDV）、收缩末容积（LVESV）和射血分数（LVEF），将RT-3DE测值与左心室造影测值相比较。结果 RT-3DE能显示室壁瘤患者左心室的整体形态，其测量的LVEDV、LVESV较左心室造影测值偏小，差异有统计学意义（P＜0．05），而LVEF差异无统计学意义（P＞0．05）。但两种方法测量LVEDV、LVESV、LVEF的相关性r值分别为0．76、0．86、0．67，相关性较好。结论 RT-3DE能够准确测量室壁瘤患者左心室容积和收缩功能。

Objective To evaluate the feasibility and accuracy of real-time three-dimensional echocardiography (RT-3DE) in measuring left ventricular volume and systolic function in patients with ventricular aneurysm. Methods Left ventricular end diastolic volume(LVEDV), left ventricular systolic volume(LVESV) and left ventricular ejection fraction(LVEF) in 21 patients with ventricular aneurysm were measured using RT-3DE and left ventricular angiography. Comparison between values acquired by RT-3DE and left ventricular angiography was taken. Results Overall shape of left ventricle with ventricular aneurysm can be showed using RT-3DE. The measurement values of LVEDV and LVESV by RT-3DE were smaller than by left ventricular angiography, which had significant difference (P<0.05).There was no significant difference in LVEF between the two methods(P>0.05). There was a good correlation in LVEDV,LVESV and LVEF between the two methods(r=0.76, 0.86, 0.67). Conclusion RT-3DE can measure accurately left ventricular volume and systolic function in patients with ventricular aneurysm.
