It can be a low complication rate procedure if you pick carefully the center and specialist that does the procedure. Tertiary referral centers have less than half the complication rate than the average clinic in the US. So experience, skills and volume are important.

There have been studies involving ablation procedures in senior people and even octogenarians, and it has been proven safe and effective with a low complication rate.
