[The correlation between pulmonary hypertension and histological findings of the pulmonary vessels in congenital heart disease (author's transl)].

In nearly 100 infants the hämodynamic and histological findings of pulmonary hypertension in congenital heart diseases are correlated when a banding-procedure was done. There were: 45 ventricle septal defects, 10 atrio-ventricular canals, 13 transpositions of the great arteries, 16 patent ductus arteriosus and 7 miscellaneous. A hämodynamic hypertension was more frequent than the histological hypertension; but there was a difference in the different heart diseases: The patients with patent ductus arteriosus and hypertension show only in a few cases histological alterations; in infants with VSD the correlation was much more better. Whether a banding procedure of the pulmonary artery is able to provide the progress of pulmonary sclerosis may be discussed after a second excision of lung-tissue when the correction of the heart disease is done.
