| 彩色多普勒血流会聚区（FCR）法是近几年发展起来的一定量二尖瓣返流的新方法。本文应用该方法，对55例显示血流会聚区的二尖瓣返流患者行FCR法与返流束面积法（SR）、返流束面积与左房面积之比法（SR/SLA）相比较，相关系数分别为0.822及0.732（P值均小于0.01）,并应用FCR法定量测定二尖瓣返流率。按不同的返流率将二尖瓣返流分为轻、中、重三度。本文认为血流会聚法为定量评估二尖瓣返流（特别是中至重度返流）一较为理想的无创性方法，具有广泛的理论研究及临床应用前景。 |

| Color Doppler flow convergence region (FCR)is a new advancing quantitative method used to measure mitral regurgitant flow in recent years.We evaluated the clinical applicability of this method in 55 with patients with showing FCR obviously.Tne ratio of maxium regurgitant jet area as well as regurgitant area-toleft atrial area were compared to regurgitant flow rate calculated by FCR method.The results showed they were closnly correlated (r=0. 822 and 0. 732, P<0.01).This method is also applied to quantitating mitral regurgita flow rate which is divided into three degrees (mild, moderate and severe).We conclud that FCR is an ideal noninvasive method in estimating the severity of mitral regurgitation,especially in moderate to severe mitral regurgitation,having jts promising prospect of theoritical studies and clinical application. |
