Summary:An equation for calculating the mean pressure in the left atrium is suggested. The area of the mitral orifice was calculated according to the Gorlin's equation on the basis of the data of polycardiography and the dye dilution method. The mean pressure in the left atrium was determined in 129 patients with acquired heart failures, the area of the mitral orifice--in 36 patients. A comparison of the calculated values with those obtained by catheterization and at surgery demonstrated their high reliability. The simplicity and safely of the method permit to use it for a dynamic observation aimed at assessing the efficacy of the surgical treatment and for timely diagnosis of possible re-stenosis.
