A patent ductus arteriosus is due in large part to increased sensitivity of the premature ductus to PGE2. After PGE2 stimulation, cAMP concentrations are higher in the immature than in the mature ...

Patent ductus arteriosus (PDA) remains a prominent clinical challenge in the management of preterm infants. During fetal life, the ductus arteriosus diverts blood away from the underdeveloped lungs, ...

Patent ductus arteriosus (PDA), one of the more common cardiac defects present at birth, is the persistence of an opening between the pulmonary artery and aorta. This opening is as a result of failure ...

SHOULD closure of a patent ductus arteriosus with reversal of flow be attempted? If so, how can the high surgical mortality hitherto reported 1–3 be reduced? An attempt is made to answer these ...

Credit: Getty Images. Evidence suggests that patent ductus arteriosus comprises anywhere from 5% to 10% of all congenital heart disease. Although the majority of congenital heart diseases (CHD) are ...

This article presents common misconceptions about the physiologic significance of early ductal shunting and reviews the evidence regarding the preferential use of echocardiography rather than reliance ...

ANGIOCARDIOGRAPHY—contrast visualization of the heart and great vessels — was first made a practical procedure by Robb and Steinberg 1 in 1938. In subsequent reports these authors have described in ...

Active treatment of hemodynamically significant patent ductus arteriosus (PDA) in preterm infants within the first 2 weeks of life was associated with worse outcomes than expectant management.

The multicentre, randomised, double-blind, placebo-controlled Baby-OSCAR trial. Participants were 653 extremely preterm infants with a large patent ductus arteriosus (diameter, ≥ 1.5 mm). In the first ...

A patent ductus arteriosus (PDA) is a persistent connection between the aorta and the pulmonary artery resulting in left to right shunting. This connection is supposed to close shortly after birth, ...
