[Architectonic characteristics of the heart ventricles in a perimembranous defect of the interventricular septum].
The results of quantitative morphological macro-, micro-, and ultrastructural (myocardial biopsies) studies of the ventricles with perimembranous septal defect in 135 infants under the age of one year have been compared. In newborns there appeared ventricular myocardial hyperplasia and low absolute and relative values of all the myocardial parameters versus normal control. At the age of 3 months the parameters were similar to or above the control ones exceeding them considerably by the age of 10-12 months. The comparison of the parameters of the septal parts showed predominant abnormality of the sinus part indicating that the perimembranous ventricular septal defect entity is a sinus one.
