It is the only area through which the interatrial septum may be traversed without the risk of cardiac perforation. The fossa ovalis is the remnant of a thin fibrous sheet that covered the foramen ovale during fetal development. The foramen ovale is a small hole located in the septum, which is the wall between the two upper chambers of the heart (atria).

Structurally it consists of the central fibrous flap valve called the septum primum that is surrounded by a ring of muscle called the septum secundum. This allows the cardiovascular system to efficiently distribute oxygenated blood throughout the body.
