Abstract:
Patent foramen ovale (PFO) is a common variant present in up to 25% of the population. Atrial septal defect (ASD) is a direct communication between the 2 atrial chambers, of which the ostium secundum variety is the most common. This manuscript is an in depth review of the complex atrial septation, the diagnosis of PFO and ASD and its clinical and therapeutic implications.
