News and Articles on Ductus Arteriosus
Beverly puppy saved by open-chest surgery Jul 12, 2009
Ayla was immediately transported to the Animal Ultrasound Clinic in Salem where doctors confirmed Borash s suspicion that the puppy suffered from patent ductus arteriosus, a condition in which the artery that provides oxygen to the fetus fails to close following birth, resulting in improper blood and oxygen circulation through the heart. In infants, this condition is known as blue baby syndrome. (Beverly Citizen, MA)
Estrogen activates critical lung genes to improve lung function following preterm birth Mar 12, 2009
Estrogen also caused the closure of the ductus arteriosus, a shunt that connects the pulmonary artery to the aorta during the primates' fetal development to allow blood flow to bypass the fetus' fluid-filled lungs. In the case of full-term infants, the ductus arteriosus normally closes at the time of birth once breathing is established. (EurekAlert!)
Uncorrected Heart Defect Ups Risk of Infant Death Feb 7, 2009
The birth heart defect known as patent ductus arteriosus, or PDA, afflicts mainly infants who are born very prematurely. The defect occurs when a large blood vessel near the heart -- the ductus arteriosus -- fails to close at birth ... Because the standard of care has been to attempt to close the PDA in preterm infants, there is little information on the outcome of infants with a persistently open ductus arteriosus. (MEDLINEplus)
