Not sure I can add anything that will help more than the vets here do for all of us newbies. I had an AN removed (that we had been watching and fretting about for 2 years) this past January 23rd, within 2 months of being told I had an ascending aortic aneurysm that I inherited. (This was the same thing that afflicted John Ritter). So, I was faced with a double whammy. I was anticipating the AN surgery, and then by accident, an CT scan caught the enlarged aorta.
I do not, nor do I pretend to know if all heart or nearby heart issues are the same, but I had my cardiologist talking in concert with my neurosurgeon up to the actual day of surgery. I made sure all communication was happening on both sides, and there was zero confusion about what I had and what we were planning to do. I came out of the surgery without any problems with the aorta exasperated.
I had a 6 hour surgery, retro behind the ear, and lost probably 85%-90% of my hearing. I will not lie and say I smiled and went on my way. The past 2 months, along with my balance, the lack of hearing, and saying "what" more times than I ever have in my life has been a frustrating challenge but I will look into alternatives to perhaps assist me. I am still a fresh postie and just now gathering my strength for the new me. Testing myself, I drove from Dallas to Galveston this past week in heavy traffic and was able to drive 7 hours one way and 6 coming back. This was good for me, as my brain really was pushed and I could feel me getting stronger with the challenge.
Still have work to do, but glad to be beyond the worry of pre-surgery things like when I had a headache, worrying if the thing was growing or not, (just typical stuff knowing you have something in your head that doesn't belong).
To sum up, I trusted my doctors, but I cut the cards. I made sure with excessive annoying phone calls and visits that they had discussed my case in detail and were in agreement to go forward.
