[Quantitative assessment of the aorta and pulmonary artery in normal subjects (comparison of data from...

Fifteen children whose age ranged from 5 to 15 years were examined by the method of two-dimensional echocardiography to calculate the quantitative characteristics of a normal aorta and pulmonary artery. To determine the character of correlation of these data with the findings of morphometric examination of the heart, the results were compared with the morphometric data in 21 children of the same age. The study showed that echocardiography makes it possible to calculate the size of the semilunar valves quite precisely. In standardization of the echocardiometric examination the parameters correlate well with the findings of morphometry, while the differences between them do not exceed 6-7%. It proved that the quantitative characteristics of the aorta and pulmonary artery were determined by the body surface area, but due to the non-linearity of their dependence on it, they change according to strictly specific patterns.
