为了评价经食管超声心动描记术鉴定冠状动脉近端狭窄的价值,对111例术中麻醉下进行经食管彩色多普勒超声心动描记术和术前一周内进行冠状动脉造影的病人加以研究,年龄34～84岁(平均61岁),男性69例,女性42例。结果和讨论:经食管超声描记记术使111例病人中的103例(93%)左冠状动脉主干从起始点完满地显影至分叉处,其中7例未显影,1例显影欠完善。103例显影完善者左冠状动脉主干长度为0.2至2.2 cm(平均0.93±0.06),管腔最大宽度为0.2至0.7 cm(平均0.45±0.01)。同时亦使不等长度的
To evaluate the value of transesophageal echocardiography in the identification of proximal coronary stenosis, 111 patients undergoing intraoperative anesthesia for transesophageal color Doppler echocardiography and coronary angiography within one week prior to surgery were studied, age 34 to 84 years (average 61 years), 69 males and 42 females. RESULTS AND DISCUSSION: A total of 103 (93%) of the 111 patients undergoing transesophageal echocardiography developed the main trunk of the left coronary artery from the starting point to the bifurcation, of which 7 were unexposed and 1 developed imperfections. The diameter of the left main coronary arteries in the 103 cases was 0.2 to 2.2 cm (average 0.93 ± 0.06) and the maximum lumen width was 0.2 to 0.7 cm (average 0.45 ± 0.01). At the same time also make unequal length
