Abstract

Mitral valvular orifice area is important for the evaluation of prognosis and treatment of patients with mitral valvular stenosis. Until recently, Gorlin's formula using cardiac catheterization has been utilized in the measurement of mitral valve area, but it is invasive and impractical to examine repeatedly. Recently 2-Dimensional echocardiography appeared to be a practical and useful substitute in measurement of valve area and also it is economical and has no risk to patients. In 31 patients with mitral valvular stenosis examined at the echocardiography room of Busan national University Hospital from March 1982 to March 1983, we measured the mitral valve area with 2-Dimensional echocardiography and evaluated its relationship with the left ventricular functions measured on M-mode echocardiogram. Among many parameters on M-mode measurements EF slope, excursion amplitude and the ratio of left atrial dimension to aortic root dimension were rather helpful for the assessment of severity of mitral valvular stenosis than other parameters. And each relationship with the valve area showed correlation coefficient of 0.60, 0.05 and -0.58, respectively.
