Patent foramen ovale (PFO) and atrial septal defect (ASD) closure

A PFO and an ASD are congenital structural heart diseases characterized by a communication between heart chambers at the level of the wall (septum) separating them. These chambers are the left and right atrium as shown on the picture below. The right atrium receives (dark) oxygen-depleted blood from the great veins, while the left atrium receives (red) oxygen-rich blood from the lungs.
