Abstract
Patent Foramen Ovale (PFO) is a remnant of fetal circulation that could be observed in the 25% of the population worldwide. PFO is associated to numerous clinical conditions as migraines, coronary embolization, transient ischemic attacks, and stroke. The main PFO concerns are related to its correlation to stroke, in particular in young adults. Despite the impact on morbidity that PFO could have, to date there is not clear evidence about its management and treatment. In this narrative review our aim is to summarize the more recent evidence in the literature dealing with PFO, in order to provide an updated overview on this topic.
