[Potential of noninvasive determination of the left atrioventricular aperture in mitral stenosis (according to data of ultrasound studies)].
The results of the measurement of the mitral opening in mitral stenosis patients by planimetry and by the computation method via the half-cycle of the atrioventricular pressure were found to be in satisfactory agreement except those in a group of patients with concomitant failure of the semilunar aortic valve. Moderate or appreciable mitral regurgitation and stenosis of the aortic ostium associated with mitral stenosis exerted no substantial effect on the accuracy of the design parameter of the mitral opening.
