“…For example, in the present sonographic study the mean diameter of the DA at its middle determined at 40 weeks of gestation was 5.7 mm, whereas in an anatomical study it was 3 mm 19 . Similar differences are found comparing the diameters of the DA and the pulmonary valve anulus determined in the present study with those of further anatomical studies 22,23 . Also the DA‐diameter/pulmonary valve diameter ratio differs substantially between the present sonographic study (0.67, SD 0.1) and the ratio of 0.35–0.4 in an anatomical study 23 .…”

“…Like Van Meurs-Van Woezik et al , 7 we believe it is important firstly to know the size of the vessels and valvar orifices in relation to normal calibers in any region to be surgically repaired. It is also important, nonetheless, to be able to predict, at least to some extent, the anticipated increase in diameter after the corrective operation.…”

Morphometric study of the great arterial trunks and their branches in the human fetal heart with perimembranous ventricular septal defects

et al. 1997

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.

“…Van Muers-van Woezik et al [6]examined neonates at postmortem and found a mean isthmus diameter of 5.5 mm (SD = 1.5), with a mean descending aorta diameter of 6.0 mm (SD = 0.61). Morrow et al [7]described a study of coarctation of the aorta, in which their control group had a mean internal diameter of 5.5 mm at the preisthmus and 4.5 mm at the isthmus, a decrease of 18%.…”

Doppler Velocity and Flow through the Aortic Isthmus in Normal Term Neonates

et al. 1999

Our hypothesis was that the relationship between the internal aortic diameter and the Doppler flow velocity across the aortic isthmus could be modeled by applying the principle of conservation of mass flow. The aortic diameter decreased at the isthmus by a mean of 18% (t = 11.02, p < 0.0001), while the flow velocity increased by a mean of 44% (t = 10.09, p < 0.0001). The mean peak mass flow rate was 34.5 ml/s preisthmus and 32.9 ml/s at the isthmus with excellent correlation (r = 0.830). We conclude that the increase in Doppler velocity observed in the descending aorta can be explained by the normal narrowing observed at the aortic isthmus and application of the continuity equation for conservation of mass flow.
