Do homework: Closing a pfo is usually not dangerous but bad things can happen. The best question is : do you need it and why? I would strongly advise to discuss the indications with your doctor and for him/her to show you all studies that advise to do it and the ones that do not. Then you can truly make an informed decision about the need for the procedure, chances of success and complications in their hands.
