Part of the interatrial wall

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

Forma parte del septo interauricular.

Puede permanecer permeable y permitir la comunicación entre las aurículas derecha e izquierda. En caso de existir comunicación entre el lado izquierdo y derecho, la válvula del foramen oval normalmente cierra y evita el cortocircuito. Puede existir un cortocircuito paradójico de derecha a izquierda en caso de que las presiones de la aurícula derecha estén elevadas.
