title: [Regional pulmonary ventilation and blood flow in patients with mitral valve stenosis according to radionuclide study].
abstract: It is shown, on the basis of ventilation and perfusion scintigraphy, that marked pulmonary flow redistribution from basal to apical departments, combined with relatively normal distribution of ventilation volumes, is a regular feature of mitral stenosis combined with pulmonary hypertension. The quantitative assessment of the intensity of pulmonary perfusion redistribution can be used as a measure of pulmonary hypertension. Also, a right-to-left unbalance was established in the pulmonary flow distribution, manifested as hyperperfusion of the left lung.
