Normally, a blood vessel needed only for
fetal blood circulation (called the ductus arteriosus) closes off at birth.
As the fetus develops, this blood vessel is kept open by a substance in the fetus's body called prostaglandin. At birth, prostaglandin decreases and the blood vessel closes.
In some premature infants, this blood vessel does not close. This is
a condition called a
patent (open) ductus arteriosus. These infants are given a prostaglandin inhibitor. It's a medicine to help the blood vessel close.
It is possible that the main title of the report Mitral Valve Prolapse Syndrome is not the name you expected. Please check the synonyms listing to find the alternate name(s) and disorder subdivision(s) covered by this report.
When an infant has certain other
congenital heart defects, a medicine that is a form of
prostaglandin is often given by vein to keep the
ductus arteriosus open. Keeping this blood vessel open allows the blood to
keep moving until the defect can be fixed to allow normal blood flow. This may require surgery or another procedure.
