[Diagnostic importance of radionuclide scintigraphy of the lungs in mitral stenosis].
The author shows close correlation between the degree of regional redistribution of the pulmonary blood flow using the radionuclide scintigraphy data and a mean pressure value in the left auricle and pulmonary artery in patients with mitral stenosis. In the course of disease development the index of upward-downward blood flow redistribution and the value of mean pressure in the pulmonary artery showed an increasing degree of correlation that indicated the development of the angiospastic component. A tendency to irregular growth of vascular resistance of the right and left lung was demonstrated. Blood flow deficiency in the right lung observed in these patients that depended on the degree of blood pressure elevation in the pulmonary artery, pointed to the predominant growth of right lung resistance.
