Age-Related Prevalence of Open Ductus Arteriosus in Full-Term Newborns.
Background: The ductus arteriosus is part of the fetal circulation. Normally, the vessel closes during the cardiac transition. Delayed closure is associated with complications. The aim of this study was to evaluate the age-related prevalence of open ductus arteriosus in full-term neonates.
Methods: Echocardiograms were collected in the population study, the Copenhagen Baby Heart Study. The present study included full-term neonates with an echocardiogram performed within 28 days after birth. All echocardiograms were reviewed to assess ductus arteriosus patency.
Results: A total of 21,649 neonates were included. In neonates examined at day zero and day seven, an open ductus arteriosus was found in 36% and 0.6%, respectively. Beyond day seven, the prevalence remained stable at 0.6%.
Conclusion: More than one-third of full-term neonates had an open ductus arteriosus on the first day of life, declining rapidly within the first week and stabilizing below 1% after day seven.
期刊介绍:
This highly respected and frequently cited journal is a prime source of information in the area of fetal and neonatal research. Original papers present research on all aspects of neonatology, fetal medicine and developmental biology. These papers encompass both basic science and clinical research including randomized trials, observational studies and epidemiology. Basic science research covers molecular biology, molecular genetics, physiology, biochemistry and pharmacology in fetal and neonatal life. In addition to the classic features the journal accepts papers for the sections Research Briefings and Sources of Neonatal Medicine (historical pieces). Papers reporting results of animal studies should be based upon hypotheses that relate to developmental processes or disorders in the human fetus or neonate.
