I'm being treated for AFIB and Heart Failure for almost 8 years, I'm now almost 70. Last week, I was diagnosed with a 4.5cm TAA, following a CT Scan. How that was not found before is stunning to me. Neither the AFIB or Hear Failure really bothered me; but, I have to say; This TAA is really freaking me out. I live on the remote tropical island of Guam. There are no Heart Surgeons here. So, based on all I can figure out, 2-3 yrs and the sand in my hour glass runs out.
