| 目的：研究彩色多普勒过返流口宽度评估二尖瓣返流的价值。材料与方法：测量31例二尖瓣关闭不全患者彩色多普勒过返流口宽度、返流长度、返流面积、瞬间返流容积及返流量和返流分数。结果：彩色多普勒过返流口宽度、返流长度、返流面积及瞬间返流容积与返流量的相关性分别为r=0.87、0.48、0.65和0.64;上述彩色多普勒参数与返流分数的相关性分别为r=0.89、0.61、0.71和0.64.彩色多普勒过返流口宽度预报重度二尖瓣返流的准确度(93.5%～96.8%)显着高于返流长度、返流面积及瞬间返流容积预报重度二尖瓣返流的准确度(71.0%～74.2%), P<0.05～0.01.结论：彩色多普勒过返流口宽度是一种比返流束更好的评估二尖瓣返流的指标。 |

| Objective:To study the value of color Doppler vena contracta(VC) in evaluating mitral regurgitation.Materials and Methods:The color Doppler VC,color Doppler regurgitant jet length(JL),jet area(JA) and instantaneous jet volume(IJV),as well as regurgitant volume and regurgitant fraction in 31 patients with mitral regurgitation were meassured.Results:The correlation between VC,JL,JA,IJV and regurgitant volume were 0 87,0 48,0 65 and 0 64 respectively,and those between VC,JL,JA,IJV and regurgitant fraction were 0 89,0 61,0 71 and 0 64 respectively.The accuracies of detecting severe mitral regurgitation by VC(93 5%～96 8%) were significantly higher than those by JL,JA and IJV(71 0%～74 2%), P <0 05～0 01.Conclusion:Color Doppler VC is a more accurate parameter than color Doppler regurgitant jet in estimating mitral regurgitation. |
