PFO diagramA PFO (patent foramen ovale) often knwon as a hole in the heart should close shortly after birth. 25% of adults still have a PFO.

 

A small percentage it causes stroke, migraine & decompression illness. We are searching for genetic markers and disease relationships that will assist with diagnosis and cure for PFO related disorders.  

 

 

 

PFO Fast Facts

 

 

  • A patent foramen ovale (PFO) is an opening covered by a flap of tissue in the wall of the heart that separates the two upper chambers or atria.
  • PFOs are very common, more than 20% of all humans have one. Estimates range from 20-30% depending on the decade of life.
  • PFO’s are found in up to 55% of young (<60 yo) patients with stroke of unknown cause and 50-75% of patients suffering from migraine with aura.
  • Unless a patient has symptoms related to a PFO or other associated heart defects, there’s no need to seek treatment.
  • Most PFO’s in healthy people are incidental findings but in some patients the PFO is related to a problem.
  • The most common problem associated with a PFO has been a stroke or a temporary neurological event and/or severe migraine headaches.
  • A PFO can allow deoxygenated blood (venous blood with a low amount of oxygen) or blood clots to pass from the right side of the heart to the left and travel to the brain, preventing blood flow to that part of the brain or lowering oxygen levels for the whole body.
  • PFO treatment for patients with strokes of unknown cause typically involves extended use of blood-thinning medication such as aspirin, or prescription drugs, or physically closing the PFO using one of several devices
  • Clinical trials have now proven PFO closure  to be effective at stroke prevention.
  • We need to understand who is at risk and how best to treat them. This is best acheived by using the latest metabolomic and genetic research techniques through the use of 'big data'. In this way we hope to unmask the true identity of the PFO.
