When the foramen ovale is closed, the … Paradoxical embolism | The Foramen ovale of the heart
Does a Foramen ovale require blood thinning? In the case of an open Foramen ovale it is not necessarily necessary to use blood-thinning medication. Thrombi can pass through the Foramen ovale, which is why the Foramen ovale indirectly increases the probability of a possible stroke in the brain or further embolisms within the large circulation. … Does a Foramen ovale require blood thinning? | The Foramen ovale of the heart
