Atrial Fibrillation

I have atrial fibrillation. I have very isolated episodes. The last one was in the summer of 2021.

A good friend also has AF and had ablation. He mentioned that in his recent discussion with his cardiologist, the cardiologist told him that ablation was being questioned due to new scientific findings. I could not find this information anywhere in my research.

I don't want to second guess my friend's comment, but I wonder if anyone here has heard of this supposed new research?
