I suspect the frequent brain UBO's on MRI scans are likely a result of this right to left PFO shunting as well as certain symptoms such as migraine and periodic hyperventilation. PFO could also be a factor in sleep apnea pathophysiology. Heavy snoring and airway obstruction is a valsalva maneuver and can cause shunting right to left, particulary if there is also desaturation. Below is an abstract of data on CFS patients at the Cheney Clinic showing an extremely high incidence of PFO using contrast bubble studies.]]> The likely condition of the FO (foramen ovale) and DA (Ductus Arteriosus) at the time of typical CFS onset are very different.  The DA is typically just a fibrous band whereas the FO is really quite thin and susceptible to
