摘要
应用多平面经食管三维超声心动图技术（３ＤＥ）对３０例冠心病患者的左室容量、射血分数等心功能指标进行了分析，并与两维超声心动图（２ＤＥ）及心血管左室造影（ＬＶＡ）所测值进行了对比，结果显示：２ＤＥ所测左室舒张末期容量、收缩末期容量、心搏量及射血分数与左室造影相应指标呈中度相关，而３ＤＥ则与左室造影相应测值呈高度相关（Ｐ值＜０．０１）；２ＤＥ所测左室射血分数（ＥＦ）高于左室造影结果（Ｐ值＜０．０５），３ＤＥ所测ＥＦ与左室造影结果无显著差异（Ｐ值＞０．０５）。表明在冠心病患者中，经食管３ＤＥ仍可较准确地定量评价左室功能，其准确性优于２ＤＥ方法。
To evaluate the accuracy and reliability of threedimensional(3DE) echocardiography in measuring left ventricular volume and ejection fraction in patients with coronary artery disease (CAD), transthoracic twodimensional echocardiography (2DE), multiplane transesophageal 3DE and left ventriculography (LVA) were performed within 24 hours in 30 patients with CAD. The results showed that: the correlations of EDV, ESV, SV and EF determined by 2DE and LVA were only moderate (r=0.86, 0.88, 0.88 and 0.89, P<0.01); whereas there were still high correlations of EDV, ESV, SV and EF measured by 3DE and LVA (r=0.93, 0.94. 0.90 and 0.94, P<0.01). The EF measured by 2DE and LVA was significantly different (P<0.05), but there were no significant difference between EF measured by 3DE and LVA (P>0.05). In conclusion, 3DE provides a highly feasible and reliable approach to the measurement of the left ventricular volume and ejection fraction, and is superior to 2DE in quantitating left ventricular systolic function in patients with CAD.
