Introduction
Before birth there are three identified "shunts" in the mammalian cardiovascular system:
- the foramen ovale, within the heart between the atria
- the ductus arteriosus, within the aortic arch
- the ductus venosus, within the liver

Foramen Ovale
Ostium Primum (week 4, stage 13) | Atrial septum (week 8, stage 22) |
Ductus Arteriosus
Week 8 (stage 22) Aortic Arch
Ductus Venosus
The vitelline blood vessel lying within the liver that connects (shunts) the portal and umbilical veins to the inferior vena cava and also acts to protect the fetus from placental overcirculation.
Absence can cause hydrops fetalis and the umbilical vein then drains directly into the inferior vena cava or right atrium.
Postnatally this shunt functionally closes then structurally closes and degenerates to form it the ligamentum venosum.

Atrial Septal Defect
- Foramen ovale defects are generally classes as atrial septal defects.
- Atrial Septal Defects (ASD) are a group of common (1% of cardiac) congenital anomolies defects occuring in a number of different forms and more often in females.
