| 摘 要： | 目的初探实时三维超声心动图(3DE)估测心室容量的可行性和准确性.方法应用Philips公司实时3DE系统采集19只离体猪心金字塔形数据库,结合相应测量软件用心尖长轴系列平面法分别测量左室容量,并与二维双平面Simpson法和猪心左室排水法实测值比较.结果从方差分析、SNK检验及直线相关分析看:实时3DE 16平面法(23.31±14.29)ml、8平面法(23.42±14.56)ml估测左室容量值与猪心左室排水法实测值(23.79±14.78)ml差异无统计学意义(P＞0.05),实时3DE 2平面法(17.94±10.46)ml和二维超声双平面Simpson法(19.67±13.46)m1测值与排水法实测值差异则有统计学意义(P＜0.05).而且实时3DE 16平面和8平面法测值与排水法实测值高度相关(r=0.98,P＜0.0001),二维超声双平面Simpson法则较逊(r=0.89).结论实时3DE是心室容量准确估测的又一可靠手段.

| Abstract: | Objective To evaluate initially the feasibility and accuracy of real-time three-dimensional echocardiography (3DE) for quantifying left ventricular volume in an in vitro experimental study. Methods Nineteen excised porcine hearts were examined by real-time 3DE and conventional two-dimensional (2D) echocardiography with Philips SONOS 7500 echocardiographic system. The measurement of their left ventricular volume examined by real-time 3DE was outlined and calculated by 2-plane, 4-plane, 8-plane and 16-plane method with the 4D Cardio-View RT of TOMTEC image system, and their results were compared with those of 2D biplane Simpson-method. The true volume of excised porcine left ventricle measured by water displacement was served as a reference standard. Results "Full volume" imaging in all excised porcine hearts was well displayed by real-time 3DE. There was no significant difference (P>0.05) between the measurements of real-time 3DE 16-plane (23.31±14.29) ml, 8-plane (23.42±14.56) ml and those of true volume of excised porcine left ventricle (23.79±14.78) ml, but there was significant difference (P<0.05) between the measurements of real-time 3DE 2-plane (17.94±10.46) ml, 2D biplane Simpson-method (19.67±13.46) ml and those of true left ventricular volume. Meanwhile,the measurements of RT-3DE 16-plane and 8-plane were high closer to those of true left ventricular volume. The correlation of real-time 3DE and 8-plane (r=0.98, P<0.0001) with true left ventricular volume was more than that of 2DE biplane Simpson-method (r=0.89). Conclusion real-time 3DE will be a valuable and accurate technique to quantify ventricular volume. |
