1990年10月～1991年3月,我们采用彩色多普勒血流显象技术(CFI),测量风心病并二尖瓣狭窄时二尖瓣口面积(MVA),并与二维超声法(2DE)及多普勒压差减半时间法(PHT)进行对照研究,旨在探讨CFI在测量MVA的价值。1 对象与方法1.1检测对象 本组34例风心病二尖瓣狭窄患者,男9例,女
From October 1990 to March 1991, we used color Doppler flow imaging (CFI) to measure mitral valve area (MVA) in patients with rheumatic heart disease and mitral stenosis and compared them with two-dimensional ultrasound 2DE) and Doppler pressure half-time (PHT) control study, to investigate the value of CFI in the measurement of MVA. 1 objects and methods 1.1 test subjects 34 patients with rheumatic mitral stenosis in this group, 9 males and ‧ females
