Patent Foramen Ovale (PFO) is a flaw in the septum in the middle of two atrial heart chambers. PFO occurs only after birth when the foramen ovale is incapable of closing. This hole between the atrial chambers allows a minor quantity of blood to pass from right to left atria. PFO escalates the chances of heart attack, stroke, and transient ischemic attack. Specialized tests, such as an echocardiogram, bubble test, and Transesophageal echocardiogram, are performed to diagnose PFO. Some additional tests might be recommended by doctors if the PFO’s presence is confirmed. A PFO closure device is used to treat PFO by performing minimally invasive surgery.

Some of the key players of the global PFO closure devices market include Abbott Laboratories, Lifetech Scientific Corporation, Occlutech, W. L. Gore & Associates, pfm medical ag, and Cardia, Inc., among others.
