Molecular and Mechanical Mechanisms Regulating Ductus Arteriosus Closure in Preterm Infants
Frontiers in Pediatrics, 2020 Failure of ductus arteriosus closure after preterm birth is associated with significant morbidities. Ductal closure requires and is regulated by a complex interplay of molecular and mechanical mechanisms with underlying genetic factors.

Anatomical and sonographic correlation of the fetal ductus arteriosus in first and second trimester pregnancy [PDF]
, 1994 Ultrasonic visualization of the ductus arteriosus in first and second trimester pregnancies was compared with postmortem preparations. Twenty human fetal postmortem specimens from 8 to 19 weeks menstrual age were examined, 11 with microscopic ...

Isolated Dissection of the Ductus Arteriosus Associated with Sudden Unexpected Intrauterine Death
Journal of Cardiovascular Development and Disease, 2021 We report five cases of sudden intrauterine death due to premature closure of the ductus arteriosus. In four cases, this was caused by dissecting the hematoma of the ductus arteriosus with intimal flap and obliteration of the lumen.

Effects of antenatal betamethasone on preterm human and mouse ductus arteriosus: comparison with baboon data. [PDF]
, 2018 BackgroundAlthough studies involving preterm infants ≤34 weeks gestation report a decreased incidence of patent ductus arteriosus after antenatal betamethasone, studies involving younger gestation infants report conflicting results.MethodsWe used preterm

Patent ductus arteriosus – not only apaediatric issue
Pediatria i Medycyna Rodzinna, 2014 The ductus arteriosus is a vascular structure of the foetal circulation that connects the great arteries and determines the blood flow from the pulmonary trunk to the aorta bypassing the pulmonary circulation. After birth, it comes to the functional and

Transcriptional profiles in the chicken ductus arteriosus during hatching.
PLoS ONE, 2019 The ductus arteriosus, an essential embryonic blood vessel between the pulmonary artery and the descending aorta, constricts after birth or hatching and eventually closes to terminate embryonic circulation. Chicken embryos have two long ductus arteriosi,

Fetal heterotaxy with tricuspid atresia, pulmonary atresia, and isomerism of the right atrial appendages at 22 weeks. [PDF]
, 2013 We report the accurate prenatal diagnosis at 22 weeks gestation of right atrial isomerism in association with tricuspid atresia. Several distinctive sonographic features of isomerism of the right atrial appendages were present in this fetus: complex ...
