For a time the two auricles communicate with each other by an opening, the ostium primum of Born, below the free margin of the septum. This opening is, however, closed by the union of the septum primum with the septum intermedium, and the communication between the auricles is reestablished through an opening which is developed in the upper part of the septum primum; Aortic sepiiim.
