Overview
During fetal development, the septal wall may fail to fuse causing an atrial septal defect to arise. An ostium secundum atrial septal defect is one such type of malformation arising from the irregular development of the foramen ovale, septum secundum or septum primum.In this there is an absence of tissue in the region of fossa ovalis. It is the most common type of atrial septal defect.
