Hi There I ahve a son who os 4 1/2 (you can't forget that 1/2) V=Crhistopiher has several issues with his heart an yes he does have a PFO since birth. his is very tiny (the size of a pin hole) and has yet to close. soif it isn't closed don't worry. as far as her turning blue, do you know if she has SHUNTING across her PFO? this can cause her to turn blue. Chris turns blue in the same area as your doctors, and his cardiac doctor thinks that is unusal. do you know how low her 02 goes when this happens? 95-100 is normal they will also say that anyhting in the 90's os okay but is is concerning when is goes lower.
Chris does tire out more easily then other kids, but I can't for sure say it is the PFO or the other stuff going on in his body, I do know that the PFO can do that. He also takes asthma medications, Pulmicort and xopenex on a daily baisis.
good luck
michelle
Yes, a PFO can cause fatigue as the blood/oxygen level pumped into circulation may be compromised. More likely, the cause of being tired can be related to low blood sugar and anemia.
