Background: Patent foramen ovale (PFO) is an independent risk factor for cerebral infarction. Since similar to 25% of the population have a PFO, the simple association of PFO with stroke is not enough to establish the diagnosis of paradoxical embolism. We evaluated possible clinical Clues to the diagnosis of paradoxical embolism.
