Abstract

　　The mitral valve area（MVA）was measured by three dimensional echocardiography（3DE）in 27 patients with mitral valve stenosis（MS）before operation. Compared with the MVA_3DE determained by surgery（MVA_OP），we found a good correlation between MVA and MVA_OP（r＝0.83）. Two dimensional echocardiography（2DE），color Doppler flow imaging（CD）and Doppler pressure half－time（PHT）were performed simultaneously before operation for the measurement of MVA，three was no significant difference among them and MVA_3DE（P>0.05），but compaired with MVA_OP respectively，the correlation coefficients of MVA_2DE/MVA_OP，MVA_CD/MVA_OP，and MVA_PHT/MVA_OP were lower than those of MVA_3DE/MVA_OP. This study suggests that 3DE may be considerable accurate in estimation of MVA in patients with MS. However，further studies on this aspect are cleatly required.
