[Wedge pressure in the pulmonary vein and artery].
Analysis of the results of measurements of the pressure in pulmonary veins and left auricle in 143 patients with mitral stenosis during the operation and the registration of the wedge pressure in the pulmonary veins during catheterization in 62 of 105 patients of another group enabled the authors to conclude that there was no autonomous pulsation of the pulmonary veins. The pressure after occlusion with a catheter of the pulmonary vein branches and the pulmonary artery does not reflect the true hemodynamic condition in the occlusion basin. The data obtained should be considered as artificial phenomena determined by the method islet.
