Patent Foramen Ovale—Paradoxical Embolism

Show Summary Details


Paradoxical embolism, arising from thrombi in the leg or pelvic veins, and passing through a patent foramen ovale (PFO) to reach the left ventricle of the heart and subsequently the brain, has become an increasingly important cause of stroke. However, as many as 25–30% of individuals have a PFO, and this common cardiac finding is often unrelated to the cause of the patient’s brain ischemia.
