Abstract
Patent foramen ovale (PFO) is a congenital cardiac variant caused by failure of the closure of a passage in the atrial septum. It is quite common, occurring in as much as 27% of the population based on autopsy studies. Most cases of PFOs are incidentally discovered or found during work-up of cryptogenic strokes as a potential cause of the stroke.1 New research is being conducted on the role PFOs play in hypoxia from intracardiac right-to-left shunting, including in patients with co-existent cardiovascular and pulmonary disease
