Fetal ductal constriction is a potentially severe functional alteration, often causing right
ventricular overload and insufficiency, tricuspid regurgitation and neonatal pulmonary …

The ductus arteriosus is a fetal vessel that allows most of the blood leaving the right ventricle
of the heart to bypass the lungs. Fetal patency of the ductus, and its spontaneous closure …

OBJECTIVE. Ductus arteriosus (DA) closure occurs within 96 hours in> 95% of neonates>
1500 g in birth weight (BW). The prevalence and postnatal age of spontaneous ductal …

We report a fetus with an unusual combination of a narrow ductus arteriosus (DA) and
foramen ovale. A pregnant mother was referred at 26 weeks of gestation for fetal pericardial …

The objective of this study was to describe the characteristic prenatal findings of a ductus
arteriosus‐dependent pulmonary circulation secondary to cardiac malformations. B‐mode …

Patent ductus arteriosus (PDA), in which there is a persistent communication between the
descending thoracic aorta and the pulmonary artery that results from failure of normal …

Prenatal closure of the ductus arteriosus (DA) is associated with maternal ingestion of
cyclooxygenase inhibitors during pregnancy. We report a case of prenatal DA closure after …

Background The ductus arteriosus (DA) is critical in maintaining postnatal circulation in
neonates with obstructed systemic circulation (OSC) and pulmonary circulation (OPC). We …

The attention which has been paid to the ductus arteriosus over the last several decades
emphasizes its important role in fetal and neonatal circulatory physiology. The pioneering …

Maintaining patency of the ductus arteriosus pending surgical intervention can be critical to
the survival of the neonate with ductal dependent congenital heart disease. Spontaneously …
