应用—维超声心动描记冠状动脉显象的方法已有10年历史.它能提供冠状动脉形态学信息,尤其是近端左冠状动脉.Vered 等(1986年)报告此法可显示出90%的冠脉左主干及50%的右冠状动脉,但影象质量较差,不能作出解剖上的评价.近年,经食管多普勒超声心动描记法能显示所有患者的心脏全部结构,包括冠脉水平的主动脉根部结构的清晰影象.目前尚未见此法用于冠状动脉的研究报告.作者以往用3.5mHz 传感器经食管超声心动图检查了1300余例,仅偶尔能检出近端左、右冠状动脉.最近,作者用5mHz 同时协调的列阵传感器连接彩色多普勒(64种成分,最大扇形角90度,Hewlett packard 21362A 型)仪,装在一改良
Application-Dimensional echocardiographic coronary imaging has been used for 10 years and provides morphological information on coronary arteries, especially the proximal left coronary artery. Vered et al. (1986) reported that this method showed 90% Left main coronary artery and 50% right coronary artery, but the image quality is poor, can not make an anatomical evaluation.In recent years, transesophageal Doppler echocardiography can show all patients with all cardiac structures, including coronary artery Of the aortic root structure of the clear image of this method has not been used for coronary artery research report of the past with the 3.5mHz sensor transesophageal echocardiography examination of more than 1,300 cases, only occasionally able to detect the proximal left and right Coronary Artery Recently, the authors connected color Doppler (64-component, 90-degree maximum fan angle, Hewlett Packard Model 21362A) instruments with a 5 mHz simultaneous array sensor in a modified
