Hello and welcome to HCM. . . .
In your history its not clear that what type of ablation has been done and where is the location of ablation.
Usually as per your history it looks like symptoms of heart failure
, which may happen in many occassion when any other location may need ablation.
If you can send me the brief report of your ablation, it will be more helpful to get some conclusion for your symptoms and plan of management.
Good luck . . .
