Matthew Price, MD, an interventional cardiologist at Scripps Clinic, discusses patent foramen ovale or PFO, a common heart condition that for some people raises puts them at risk of cryptogenic or unexplained stroke.
Dr. Price explains how a device known as a PFO Occluder works to reduce the risk of cryptogenic stroke.
A PFO is a persistent connection or hole between the left and right sides of the heart that can get you in trouble when you age and be the source of a cryptogenic stroke.
A cryptogenic stroke is a stroke from an unknown cause that we believe is due to a PFO in many cases.
The warning signs of a stroke are neurological things, such as numbness or tingling of the arms or legs, inability to move one or more sides of your body, and inability to speak or be clear when one speaks.
A PFO Occluder is a device we can use to plug the persistent hole between the left and right sides of the heart. There are two types. There is the AMPLATZER PFO Occluder, which is made out of a special nitinol mesh or metal mesh with two discs, and there's the GORE CARDIOFORM Occluder, which is also made of two discs, out of medical grade Gore-Tex.
The PFO Occluders work by sealing up that connection or that hole between the right and left sides of the heart so that blood clots from the legs can no longer cross over through that hole and cause a stroke.
