The ostium secundum (or foramen secundum) is a foramen in the septum primum.

It should not be confused with the foramen ovale, which is a foramen in the septum secundum.

Clinical significance

An ostium secundum which persists at large size can be a source of atrial septal defects. [eMedicine|ped|1686]
