| Precursor | foramen ovale |
Found in the right atrium of the heart, the fossa ovalis is an embryonic remnant of the foramen ovale, which normally closes shortly after birth.
In a heart specimen of a neonate, the fossa ovalis is translucent, but later in life the membrane thickens. [1]
Clinical significance
Failure of the foramen ovale to close results in a disorder known as patent foramen ovale.
