Abstract

Morphometric methods were used to study hearts with perimembranous ventricular septal defects in 22 human fetuses and neonates weighing from one to 3.8 kg (2.221±0.852 kg). All specimens displayed concordant atrioventricular and ventriculoarterial connections, and all had perimembranous ventricular septal defects. A total of 17 interventricular parameters (nine in the right ventricle and eight in the left) were measured in each specimen. The values were compared with patterns of normality established by Rowlatt and her colleagues in hearts from 83 children ranging in age from birth to 15 years. These patterns were found to be less reliable than our own data from fetal and perinatal hearts from children ranging in age from birth to one month. Our morphological data, when appropriately interpreted, have immediate clinical and surgical applications in the treatment of fetal and perinatal cardiovascular disorders.
