What do you understand by the term 'patent foramen ovale' ?
In the fetus, the right and left atria communicate with each other through an oblique valvular opening, which is called the foramen ovale.
The foramen ovale persists throughout fetal life. After birth, the left atrium receives blood from the lungs and the pressure in this chamber becomes greater than that in the right atrium; this causes the closure of the foramen ovale.
