Imaging characteristics of ischemic strokes related to patent foramen ovale.
BACKGROUND AND PURPOSE Subclinical atrial fibrillation (AF) and patent foramen ovale (PFO) are the major causes of cryptogenic stroke, and neuroimaging may help distinguish the cause. We compared the imaging characteristics of ischemic stroke caused by PFO (PFO-stroke) and AF (AF-stroke). METHODS We recruited 117 patients with PFO-stroke and 358 patients with AF-stroke after excluding other c...
متن کاملPercutaneous device closure of patent foramen ovale for cryptogenic strokes/transient ischemic attacks.
We recently read with interest the recent meta-analysis performed by Agarwal et al. (1) describing transcatheter closure versus medical therapy for patent foramen ovale (PFO) in prevention of recurrent presumed paradoxical embolism. We believe our study (2), which described 1 of the largest series of PFO patients with presumed cryptogenic stroke or transient ischemic attack (TIA) up to that dat...
متن کاملPatent Foramen Ovale
The patent foramen ovale (PFO) is a normal interatrial communication during fetal life that persists after birth in approximately 1 of every 4 adults. PFO is a potential route for embolic transit from the systemic venous circulation to the brain. Though there is compelling circumstantial evidence implicating PFO, the precise role of PFO in the pathogenesis of cryptogenic stroke is not yet estab...
متن کاملPatent Foramen Ovale
Patent foramen ovale (PFO) is not uncommondit appears in perhaps 10% to 25% of the populationdbut only a small percent of cases will produce any clinical sequelae, such as refractory hypoxia, orthodeoxia-platypnea syndrome, or migraine headaches. PFO is most notorious, however, for its association with paradoxical embolus and cryptogenic stroke (1). Conclusive proof of a causal relationship bet...
متن کاملPatent foramen ovale.
Patent foramen ovale (PFO) is a common developmental anomaly that allows for the passage of blood and other substances from the venous to the arterial circulation. The study of PFO closure has been challenging due to widely available off-label closures performed outside the clinical trial setting. To date, no study has demonstrated benefit of closure using intention-to-treat analyses. Secondary...
