报告经食管三维超声心动图(3D-TEE)59例临床应用的体会。此检查所获图像可分三个区域:右区可显示上腔静脉、右房、房间隔与左房等,并能观察房间隔缺损的位置、大小、形状与类型。中区显示两条大动脉的起源与走向,右室流出道狭窄者见流出道有环形嵴状凸起,呈现出葫芦状的双腔右室。左区能显示整个左室、左房的大小,二尖瓣的形态与对合情况,二尖瓣脱垂者可见叶瓣游离缘处某一区域向左房脱出。观察表明:3D-TEE轮廓清晰,形象直观,有利于解剖结构的辨识和空间方位的理解,对多种心脏疾病的诊断有一定帮助。
Report of clinical application of transesophageal three dimensional echocardiography (3D-TEE) in 59 cases. The image obtained by this examination can be divided into three areas: the right area can show the superior vena cava, right atrium, atrial septal and left atrium, and can observe the location, size, shape and type of atrial septal defect. Central area shows the origin and direction of two major arteries, right ventricular outflow tract stenosis see outflow ring ridge has raised, showing a gourd-shaped double chamber right ventricle. The left area can show the entire left ventricle, left atrial size, mitral valve shape and the situation, mitral valve prolapse can be seen at a free region of the leaf to the left atrial prolapse. The observation shows that the outline of 3D-TEE is clear and the image is intuitive, which is good for the identification of anatomical structures and the understanding of spatial orientation. It is helpful for the diagnosis of many kinds of heart diseases.
