Resource summary
Fetal Circulation
Foramen Ovale
Normally closes at birth and forms the fossa ovalis (depression in RA)
Closes due to decreased pulmonary pressures and when the LA pressure exceed the RA pressure
In about 30% of adults they may still have a small PFO that hasn't closed completely at birth, this can increase risk of cerebrovascular events
Fetal cardiac shunt which allows blood to enter the LA from the RA
Allows blood to bypass the nonfunctional fetal lungs while the fetus obtains its oxygen from the placenta.
Develops in the late 4th of gestation
Ductus Arterosis
Connects the PA to the proximal descending aorta
Allows most of the blood from the RV to bypass the fetus's fluid filled non-functioning lungs
Upon closure at birth becomes ligamentum artiosum
Non functional and formed within three weeks of birth
Can play a role in major trauma as it fixes the aorta in place and during rapid recoil can result in a ruptured aorta
Patent ductus arteriosis
When the ductus arteriosis fails to close
