My dad is 82 and is experiencing fatigue, shortness of breath, and dizziness. he is now on eluiquis as of a month ago and we found out he has a PFO and may have had since birth. He has had an echocardiogram and a TEE. Is there any surgery at his age or perhaps a different treatment. Two cardiologists are not sure surgery will fix the “real” issue. They have now ordered a six minute walk test-and recommend the linq monitor.
