"The overlapping portions of the septum primum and septum secundum fuse completely after birth, with no communication between the right and left atria."
"The cranial overlapping portions of the septum primum and septum secundum fuse, but the caudal portions remain separate. Thus, right atrial blood can enter the resulting cavity, but there is no defect within the atrial septum for blood to cross the septum. This is called a right atrial septal pouch 2-4."
"The caudal overlapping portions of the septum primum and septum secundum fuse, but the cranial portions remain separate. Left atrial blood can enter the resulting cavity, but there is no defect within the atrial septum for blood to cross the septum. This is called a left atrial septal pouch 2-4."
"There may be a complete lack of fusion of the septum primum and septum secundum. The resulting defect in the atrial septum is called a patent foramen ovale (PFO) 2. A PFO is functionally closed by the higher pressure in the left atrium, but transient increases in right atrial pressure that exceed left atrial pressure (e.g. during a Valsalva manoeuvre) may result in right-to-left shunting of blood."
