Location:
Part of the interatrial wall

Function:
Can remain patent and allow shunting between the right and left atria; in cases of an open communication between the left and right side, the foramen ovale valve typically closes and prevents shunting; a paradoxical right to left shunt can occur in these cases if right atrial pressures are elevated
