You are talking about electrical issues inside the heart. Most ablations are successful, but it does not mean you won't develop new electrical areas causing afib even in same location.

I had an ablation on my RV several years ago. It worked and stopped PVCs in RV. It is still working, and I do not get PVCs in RV. I get PVCs in LV. I wanted to do ablation on it as RV one worked.

However, my very experienced Mayo Jacksonville EP wanted to try medications first. Why? Because the electrical PVCs came from 3 different areas and would be much more difficult to treat with ablation.

I was put on Mexiletine (spell) which cut my PVCs in half, and I have not had VTAC since.
So my RV ablation has lasted over 5 years.
