“…Length of the duct in the same periods range between 2 mm and 5 mm [36]. This data confirm that increase of the length of the DA with advancing gestational age was found Mielke and Benda [36] and Alvarez et al [27]. Another prenatal sonographic studies concerning on ductal diameter are based on a small number of cases.…”

AbstractPatent ductus arteriosus (PDA) is the most prevalent cardiovascular defect and is more often seen in females; premature babies are at increased risk. For both sexes, a relationship exists between the risk of this defect occurring and the higher dimensions of the ductus arteriosus. In this study, we examined the relationship between the dimensions of the ductus arteriosus (diameter, length, capacity) and sex. We analyzed a total of 223 fetuses, 108 males and 115 females, ranging in age from four to eight months of intrauterinal life. All fetuses of normal karyotype were obtained from spontaneous abortions. None of the analyzed specimens demonstrated any visible malformations. The increase in the length and diameters of the ductus is linearly related to gestational age. The volumetric growth of this vessel was dependent on fetal age, according to the exponential function. The large number of analyzed specimens allows reliable determination of the ductus arteriosus dimensions in consecutive months of fetal life. The data obtained could be of prognostic value during echocardiographic follow-up in the fetus. We found that the dimensions analyzed did not differ with regard to sex. It is a contradiction that, more frequently PDA in females is caused with the gender differences in the dimensions of ductus arteriosus.

“…A geometric model of the human fetal aortic arch representing the late gestation period (24 to 34 weeks) was created using computer aided design software (Proengineer) , Fig 1a. Anatomical dimensions and orientations were selected based on literature (Achiron et al, 2000;Long, 1990;Mielke et al, 2000b) and confirmed through interviews with three experienced pediatric cardiologists. The parametric nature enabled practical implementation of several suggested anatomical corrections.…”

This study focuses on the dynamic flow through the fetal aortic arch driven by the concurrent action of right and left ventricles. We created a parametric pulsatile computational fluid dynamics (CFD) model of the fetal aortic junction with physiologic vessel geometries. To gain a better biophysical understanding an in vitro experimental fetal flow loop for flow visualization was constructed for identical CFD conditions. CFD and in vitro experimental results were comparable.Swirling flow during the acceleration phase of the cardiac cycle and unidirectional flow following mid-deceleration phase were observed in pulmonary arteries (PA), head-neck vessels, and descending aorta. Right-to-left (oxygenated) blood flowed through the ductus arteriosus (DA) posterior relative to the antegrade left ventricular outflow tract (LVOT) stream and resembled jet flow. LVOT and right ventricular outflow tract flow mixing had not completed until ~3.5 descending aorta diameters downstream of the DA insertion into the aortic arch. Normal arch model flow patterns were then compared to flow patterns of four common congenital heart malformations that include aortic arch anomalies. Weak oscillatory reversing flow through the DA junction was observed only for the Tetralogy of Fallot configuration. Pulmonary Atresia and Hypoplastic Left Heart Syndrome configurations demonstrated complex, abnormal flow patterns in the PAs and head-neck vessels. Aortic Coarctation resulted in large scale recirculating flow in the aortic arch proximal to the DA. Intravascular flow patterns spatially correlated with abnormal vascular structures consistent with the paradigm that abnormal intravascular flow patterns associated with congenital heart disease influence vascular growth and function.
