I am an otherwise healthy 61 yr old female who has had 2 suspected "TIA's, 2 yrs apart. All tests proved that I had no clogs, etc. but a TEE had the following: An atrial septum aneurysm, PFO with clear left to right shunting. It also said a bubble contrast study showed a right to left shunting with moderate mitral regurgitation. I am confused about the fact that the shunting goes both left to right and right to left, & the seriousness of that. I had an appt with a specialist that said that since I have had GI bleed in the past & am on meds for that, he recommended a procedure to close the PFO. My question is: Is there anyone out there who has had similar diagnosis & what route/options did they choose? I am not afraid of the procedure, but am confused as to whether closing the hole will take care of all of the problems?? Appreciate any comments?? Thanks, Mattie16
