Overview
Association of cryptogenic stroke/transient ischemic attacks with patent foramen ovale
- One in every four cases of ischemic stroke does not have an identifiable cause other than cryptogenic stroke which is a diagnosis of exclusion[1].
- Cryptogenic stroke occurs more commonly in younger patients.
- The association between the presence of a patent foramen ovale and cryptogenic stroke is controversial and inconsistent. While some studies have demonstrated an increased incidence of patent foramen ovale (PFO) in younger patients with cryptogenic stroke [2] others failed to show an association [3].
Patent foramen ovale and first stroke
Although, two prospective cohort studies namely, ‘ The Northern Manhattan Study’ (NOMAS) and 'Stroke Prevention: Assessment of Risk in a Community' (SPARC) found an increased incidence of first stroke in patients with patent foramen ovale, both these studies did not reach a statistical significance.
