Question

During the initial assessment of a preterm infant, it is noted that the infant has a heart murmur. Which shunt from fetal life most likely remains open

Answer 1

Ductus Arteriosis shunt from fetal life most likely remains open.

What about ductus arteriosis?

• The foramen ovale, ductus venosus, and ductus arteriosus are the three shunts in the fetal circulation.
• Two umbilical artery and one umbilical vein are also present.
• These blood vessels close after birth and develop into ligaments.
• A murmur heard in a preterm newborn soon after birth would be considered to be a ductal murmur since there is a larger possibility that the ductus arteriosus will remain open in a preterm infant.
• Some organ systems, such as the central nervous system, are teratogen-sensitive throughout the whole pregnancy.
• The baby's brain and spine make up its central nervous system.
• Alcohol is one teratogen that has an impact on the central nervous system.
