多平面经食道三维超声心动图测量无灌注区心肌重量的实验研究

Quantitative Determination of Non perfused Myocardial Mass by Multiplane Transesophageal Three dimensional Echocardiography

为了探索测量急性心肌梗塞范围的新方法，在１７条实验犬中，应用多平面经食道超声技术和自制的左室三维重建计算机软件，测量了犬冠状动脉左前降支结扎后的无灌注区心肌重量，并与Ｅｖａｎｓ蓝染色方法测量的无灌注区心肌重量进行了对比，结果获得了高度的相关关系（ｒ＝０．９０，ｓｘ＝３．８ｇ）。表明多平面经食道三维超声心动图为定量评价心肌梗塞范围提供了较为简便和可靠的新途径。

In order to develop a new method of quantitative determination of acute myocardial infarction, multiplane transesophageal three dimensional echocardiography was applied to 17 experimental dogs to measure the non perfused myocardial mass resulted from ligation of coronary artery, and the results were compared with those of Evans blue staining. It showed that the results of these two methods correlated highly with each other (r=0.90, s =3.8g). We concluded that multiplane transesophageal three dimensional echocardiography provides a new method that is relatively convenient and feasible for quantitative evaluation of acute myocardial infarction.
