Patent 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...
متن کاملUsefulness of percutaneous closure of patent foramen ovale for hypoxia.
We report a patient with hypoxia secondary to a right-to-left shunt through a patent foramen ovale, following aortic root, valve, and arch replacement due to an aortic dissection in the setting of the Marfan syndrome. Following the operation, he failed extubation twice due to hypoxia. An extensive workup revealed a right-to-left shunt previously not seen. The patent foramen ovale was closed usi...
متن کاملGiant Chiari network, foramen ovale, and paradoxical embolism.
A Chiari network is identified in the course of 1.3% to 4% of all autopsies and in 2% of patients who undergo transesophageal echocardiography. This network is associated with patent foramen ovale (PFO) in up to 80% of cases. Moreover, a number of scientific articles have linked this association to the development of stroke. The patient, a 78-year-old man with a history of embolic stroke and no...
