Abstract

Morphometric methods were used to study the great arterial trunks in a total of 22 human fetuses and newborn subjects weighing from 1 to 3.8 kg (mean 2.22 ± 0.85 kg). All specimens displayed concordant atrioventricular and ventriculoarterial connections, and all had perimembranous ventricular septal defects. Thirteen different parameters were measured in each specimen, comprising the orifices of the great arterial trunks, ascending aorta, vessels branching from the aortic arch, the aortic isthmus, descending aorta, pulmonary trunk, orifices of the pulmonary arteries, and arterial duct. The values were Compared with patterns of normality established in an earlier study using hearts from 496 human fetuses and neonates weighing form 60 to 5000 g. Minimum square regression analyses were used to study the relationships between fetal and neonatal log body weight in kilograms, and the various cardiometric parameters. We believe that these morphometric data have immediate clinical and surgical applications in the treatment of fetal and neonatal cardiovascular disorders.
