[Anatomical and functional evaluation before and after the operative treatment of mitral stenosis via echocardiography].

A confrontation was made of the echocardiographic data and the operation findings in 33 patients with "pure" mitral stenosis confirmed by catheterization and intraoperation. A significant correlation was found between the decelerated movement rate of the diastolic part of the anterior mitral cusp (E--F) and the mitral stenosis degree. The not negligible diagnostic value upon the position of the posterior mitral cusp during diastole is stressed--forward of the horizontal, passing through point C of the mitral closing, as well as upon the size of the left ventricle. The correlation between the valvular calcinosis, established by the echocardiogram and that, established at the operation proved to be poor.
