I recently had a small stroke and a TIA apparantly, one on either side of my brain . I have an ASD and ASA, they mentioned about maybe getting this fixed, I am concerned that going through surgery would just create more issues. I have been on blood thinners for 6 yrs after they discovered I had APS/hughes symdrome with acL antibodies and I had a DVT in my jugular vein. They now have me on asprin therapy as well as cholesterol meds too. During the TEE and the bubble test, all the bubbles seemed to go over to the other side - how serious a risk is this and would surgery be the only answer?
