Summary

The role of a PFO as a risk factor for ischemic stroke has been established in recent years, particularly for strokes that lack an apparent cause (cryptogenic). Approximately 25% of the general population has a PFO, and it has not been shown to increase the risk of ischemic stroke. On the other hand, the prevalence of PFO is significantly higher in patients with cryptogenic stroke; up to 40% of ischemic cryptogenic strokes have a PFO, suggesting that paradoxical embolism through a PFO may be associated in a number of cryptogenic strokes.We present a 62 year-old female with ischemic stroke and PFO
