In our study we estimated mitral orifice area by use of two dimensional echocardiography in 59 patients with mitral stenosis form February 1979 till June 1981. We classified them to 3 subgroups by severity of mitral stenosis as Cope was done in 1975. and investigated correlationship between the severity and other various echo-cardiographic findings indices such as mitral valve calcification, posterior mitral leaflet motion, doming of mitral valve, EF slope, ED amplitude, LA dimension, LA/Ao ratio and especially mitral valve closure index. The following results were obtained. 1) We could accurately estimate mitral orifice area by two dimensional echocardiography. 2) Except EF slope and MVCI, we could find that various echocardiographic findings were poorly correlated with mitral orifice area measured from two-dimensional echocardiography. 3) MVCI was overlapped less frequently than EF slope in severe, moderate and mild mitral stenosis, and we could find that MVCI reflected the extent of mitral stenosis more accurately than EF slope.
