Patent ductus arteriosus is a condition in which a gap between two of the main blood vessels leading from the heart fails to close after birth. In recent years the approach to this condition has changed from one where an immediate medical or surgical approach was used to a more conservative one in which doctors wait to see if the hole closes by itself. In this study Valerie Y. Chock, from Stanford University School of Medicine, led a team of researchers comparing how new-born babies fared under the old and new approaches. She concluded that there was no difference in adverse clinical outcomes between the two approaches or significant difference in “resource utilization.”
