双平面经食道彩色多普勒血流成像的临床应用

Clinical Application of Biplane Transesophageal Color Doppler Echocardiograhy

本文总结了300例双平面经食道彩色多普勒血流成像的临床应用结果。重点介绍了心脏纵切面图像及其临应意义;双平面经食道超声心动图的适应症及其切面的选择;讨论了双平面经食道超声心动图的优越性及其局限性。本文的结果表明:双平面经食道超声心动图除具有和经胸壁超声心动图相比较的优点之外,和单平面经食道超声心动图相比较亦颇具优越性,为诊断心血管病开辟了一个新窗口。

In order to further enhance the color transesophageal echocardiography technique, we recently tested a biplane transesophageal echocardiographic probe in clinical study. Subjects to be studied consisted of 163 men and 137 women, whose ages ranged from 13 to 75 years with a mean age of 47.6 years, and included 113 patients with valvular heart disease, 81 patients with cardiac valve heart disease, 25 patients with cardic valve prostheses, 19 patients with cardiomyopathy, 13 patients with aortic dissecting aneurysm, 5 patients, with atrial mass, 15 normal subjects and 29 miscellaneous cases, Biplane transesopageal imaging could offer additional new views of the heart such as a long axis view of the ascending and descending aorta, a long axis view of the right ventricular outflow tract, a long axis view of the superior vena cava, a sagittal view of the left heart which have been found to be of more important diagnostic value in some situations compared with the conventional uniplane transesophageal echocardiography. Biplane transesophageal imaging has impacted on the evaluation of mitral regurgitation, aortic dissecting aneurym, valve replancement, obstruction of superior vena cava, stenostic right ventricular outflow tract and etc.
