1 A patent foramen ovale (PFO) is an opening covered by a flap of tissue in the wall of the heart that separates the two upper chambers or atria. 2  PFOs are very common, more than 20% of all humans have one.3  Estimates range from 20-30% depending on the decade of life.

Perfluorooctanoic acid (PFOA) has been a manufactured perfluorochemical and a byproduct in producing fluoropolymers.Perfluorochemicals (PFCs) are a group of chemicals used to make fluoropolymer coatings and products that resist heat, oil, stains, grease, and water.FOA was used particularly for manufacturing polytetrafluoroethylene, but since 2002, manufacturers have used a new process not requiring this chemical. PFOA persists in the environment and does not break down. PFOA has been identified in bodies of water and in a variety of land and water animals.
