sorry i just read your post.i usually post in chronic pain and i only come here now and then .
In regards to your question the pfo is real tiny about the size of apencil eracer.I had the pfo done last june. in my case the hole was very small .I was told it was best to have it done as it could cause blood to leak and might cause a stroke,so i had it done after my husband and i talked at lenght with my cardio dr,i was in the hospital 5 or 7 days something like that.I was on plavix for 6 months and after that i now only take a 81mg of asprin a day.I do go for echo every 6 months just to be sure everthing is ok and so far so good[KNOCK WOOD}}
I have ddd and so i get the next pain and arm pain now and then but i think it is due to that.as far as the chest pain goes i have not have any big problems with that.
I would say it took me about a good 3 months to really start to get my engery back.and i do have other problems not realated to the pfo or my heart.with me i think it was a good choice and while i will say i was scare and when it came time to have it done i was a mess.they usually dont put you to sleep for that they just sedate you but i was such a nervous wreck my cardio put me to sleep for it.so if you do decide to have it done that is something you can ask your dr if you rather be put to sleep.
Im am not sure if the size of the hole would determined the size of the pfo.ask your cardio as i would not want to give you any infro that is not right.I do know that my carido gave me a dvd to take home and i could see just what they were going to do.
in any case if you have any more question please feel frr to ask and i will be sure to check the heart forum more often,
best of luck to you and whatever you decide to do please know i iwll keep you in my thoughts and prayer's
