Two new case series suggest transcatheter device closure of patent foramen ovale (PFO) and atrial septal defect can be safely achieved with very little residual shunt in patients with a previous ...

DEFENSE-PFO took its cue from early studies suggesting that PFOs more likely to be linked to stroke are those with large shunts and/or with atrial septal aneurysm or hypermobile septum. As Song noted ...

Detection of a PFO is accomplished by demonstrating a right to left shunt with a transthroacic echocardiogram (TTE), a TEE or transcranial Doppler (TCD) performed with agitated saline.

Transcranial Doppler (TCD) ultrasound is not only better than transesophageal echocardiography (TEE) at identifying patent foramen ovale (PFO), it also better predicts ... studies had detected a right ...

Could the presence of a patent foramen ovale ... This valve opening provides a right-to-left heart shunt so ... and results must be confirmed with an intracardiac or transesophageal echocardiogram.

The association between migraine with aura and persistent foramen ovale (PFO), as well as other right-to-left shunts, is described. A hypothesis that might explain this association is discussed.

After undergoing an echocardiogram, I was surprised to be told that I have a patent foramen ovale. The cardiologist said I don't need to be treated for it, but I'm still worried.

An important role for patent foramen ovale in the pathogenesis of ischemic stroke was first suggested by a case–control study that showed a markedly higher frequency of patent foramen ovale ...

A PFO was detected in 68% of the divers. High-risk PFO occurred in 37% overall. During a mean follow-up of 28.7 months, the incidence of decompression illness was 12.8%.

Your patent foramen ovale is located in the area of the heart between the left and right atria—the two upper chambers of the heart. ... Transesophageal echocardiogram.

Patent foramen ovale (PFO) may be associated with migraine, especially migraine with aura (MA), when the PFO is permanent right-left shunt (RLS), large RLS, and large-size PFO, a recent study found.
