AFib and TKR

I've been under a tremendous amount of stress for the past six months due to significant pain in my knee and lower back, dealing with a hospital falsifying my medical records, and overall despair about what seems to be my fate to not be able to have a much needed total knee replacement surgery. Every way I turn, I seem to be blocked from ever getting this surgery Without it, I am doomed to a shortened life filled with pain, decreasing mobility, and increased cardiac problems due to not being able to exercise and keep my heart and body healthy. After my knee gave out last September, it looked like I was going to have a knee replacement surgery in January. I had just changed to new cardiologist at a hospital I had gone to about 30 years ago. Little did I know that during the time I had not been going to that hospital for any reason, there had been a mixup of my records with another person of the same name. She had Type 2 diabetes. So my new cardiologist thought it was me and refused to approve my surgery. Because he was intimidated by my complicated medical history (I had endocarditis in 2019), he started adding ridiculous things to my records, cherry-picking things from my care provider's records from the time of my illness and resurrecting them, then confirming them as being current condition that are being actively treated. These are lies. The only thing I can figure is that he's trying to discredit me to distract from his lack of knowledge. I've worked hard and uncovered a lot. My proof that these are lies is solid. But now, there's a new problem. Months of stress and not being able to sleep well due to the pain have taken a toll. My current cardiologist just told me that my pacemaker monitor revealed that I had 5 hours of AFib. We haven't talked about it, but I suspect that this means that once again, I'm going to be told that it's too risky for surgery. If my suspicions are correct, what this really means is that I have a chance of dying if I have the surgery, and a certainty of dying early because I cannot. Has anyone had a TKR after having an AFib incident?
