Abstract
Successful surgical treatment in children with congenital heart disease and hypoplastic pulmonary arteries depends on the size of the pulmonary artery tree. For this reason we determined normative angiographic data from cineangiograms of 51 infants, children and adolescents without heart disease (n=16) or with cardiovascular malformations which had no hemodynamic relevance (n=35).
Systolic and diastolic diameters of the pulmonary artery anulus, pulmonary artery sinus, pulmonary artery trunc, as well as those of the right and left pulmonary arteries were determined. The corresponding systolic and diastolic diameter values were averaged in order to obtain a mean diameter of each vascular segment. All measurements were correlated with the body length and the body surface area (BSA). A root exponential function [√y=a(1-e-bx)+c] was used, the regressions coefficients of which can be explained by physiological means. In this function c2 is the theoretical minimal diameter and (a+c)2 the theoretical maximal diameter of a cardiovascular structure; in this way the growth of the cardiovascular dimensions could be well defined mathematically and correlated strongly (r=0,99) with body length and BSA. Different exponents were found for the pulmonary artery anulus, sinus, trunc as well as right and left pulmonary arteries.
These data on normal values for the angiographic measurements of the pulmonary artery anulus and arteries at different age are useful for the identification of patients with hypoplasia of the pulmonary artery tree and serve as a valuable guide for cardiac surgery.
