Abstract:
Mitral effective regurgitant orifice area was measured by using color Doppler flow convergenee method,and its value on quantilarian of mitral insufficiency Was evaluated.The results showed that the parameter was correlated well with regurgitant volume,regurgitant fraction,color Doppler jet beginning width and jet area(r=0.89、0.84、0.82 and 0.67 respectively,P<0.001～0,0001).The accurate rate in differentiating mild and moderate from severe mitral regurgitation was 95.7% with the effective regurgitant orifice area≥30mm2.The effective regurgitant orifie area is a good parameter in quantification of naitral insufficiency.
