If I understand your question correctly you describe having an ablation for PACs and not Afib. PAC ablations are less common than Afib due to the high degree of difficultly in accessing the nodes. My EP does not do ablations strictly for PACs as he claims he literally has to be in the spot the are originating from and seeing them fire while he is performing the surgery. So comparing it to Afib is apples and oranges. But that said I recently had my 2nd Afib ablation (1st ablation May/2019) by the same doc and he suggested that during the procedure for Afib he was able to access areas for PVCs and PACs but he was unsure if what if any relief I would see. In other words no promises. He suggested it would take some time to know the results for PACs and PVCs both of which I have at times had intermittent burdens fo 25%.
That said this link https://pubmed.ncbi.nlm.nih.gov/33533993/ suggests that new mapping strategies give good results for PAC ablations. "Mapping strategies and ablation of premature atrial complexes"
