[Normal nomogram of the pulmonary artery].

With the aim to establish quantitative characteristics of the pulmonary artery in order to use them in planning operations on congenital heart diseases, the data of morphometric investigations on the pulmonary artery has been studied in 83 hearts of newborns, children and mature persons died from causes not connected with any cardiovascular disorders. The regression equations are calculated; they reflect certain dependence between the quantitative characteristics of the pulmonary artery and the area of the body surface.
