Atrial septal defect (ASD) is a congenital heart defect in which blood flows between the atria (upper chambers) of the heart.Some flow is a normal condition both pre-birth and immediately post-birth via the foramen ovale; however, when this does not naturally close after birth it is referred to as a patent (open) foramen ovale (PFO).
St. Jude Medical RESPECT Trial for PFO Closure Provides Clinical Evidence of Risk Reduction in Prevention of Recurrent Cryptogenic Stroke Results offer compelling evidence for closure with the ...
Balloon septostomy is the widening of a foramen ovale, patent foramen ovale (PFO), or atrial septal defect (ASD) via cardiac catheterization (heart cath) using a balloon catheter. This procedure allows a greater amount of oxygenated blood to enter the systemic circulation in some cases of cyanotic congenital heart defect ( CHD ).
Although closure of a patent foramen ovale or atrial septal defect theoretically removes the pathway for an arterial embolus to enter venous circulation and cause a paradoxical embolism, data suggests that closing intracardiac shunts is no more effective than medical management alone in preventing strokes.

A major grower said this week it was abandoning its citrus growing operations, reflecting the headwinds Florida's signature crops are facing following a series of hurricanes and tree diseases.
Surgical intervention should result in full closure of the foramen secundum, and mortality rates are similar to those for general anesthesia. [8] The repair can be made by suturing the atrial septum or, if the foramen secundum is large in size, a patch can be made from the patient's pericardium to fully separate each atrium.
