@ckomis I am on peritoneal dialysis right now. But, Dec 2021 I had a fistula placed in my right forearm, in anticipation to use it if it became necessary. Interesting, in Sept 2022 that fistula stopped working, and "closed down". But, it is still there!

In a couple of weeks I have an appointment with a cardiologist. I do plan to ask him if my fistula is playing a part in the concerns they are sussing out. Frankly, I had never heard of this before. Have you sought an opinion to have the fistula reversed?
