摘　　要：目的　探讨彩色多普勒血流会聚法在主动脉瓣反流定量诊断中的临床应用价值。方法　选择近端血流会聚角呈水平型的单纯性主动脉瓣反流患者 48例 ,分别应用血流会聚法和常规多普勒超声法测量有效反流口面积 (ERO)。结果　血流会聚法和多普勒超声法测定的ERO分别为 (0 .3 2± 0 .17)cm2 和 (0 .3 3± 0 .16)cm2 (P >0 .0 5 ) ,二者之间存在极好的相关性 (Y =0 .99X -0 .0 1,r =0 .97,P <0 .0 0 0 1)。结论　在近端血流会聚角为水平型的主动脉瓣反流患者 ,血流会聚法能够准确地测量ERO ,是一种简便。Objective To investigate the clinical usefulness of color Doppler flow convergence(FC) method in the quantification of aortic regurgitation.Methods Using FC and conventional Doppler echocardiography(DE) methods,the effective regurgitant orifice area(ERO) was calculated in 48 patients with isolated aortic regurgitation and a flat proximal flow convergence angle.Results ERO calculated by FC and DE method were respectively ( 0.32 ± 0.17 )cm 2 and ( 0.33 ± 0.16 )cm 2 (P> 0.05 ).An excellent correlation exists between the two methods (Y= 0.99 X- 0.01 ,r= 0.97 ,P< 0.0001 ).Conclusions FC method for measuring ERO with feasibility in aortic regurgitation with a flat proximal flow convergence angle,provides a reliable approach to quantify aortic regurgitation.
