So, if you have verified AVNRT or AVRT ablation is always a treatment option.
Ablations have a very high curative rate (up to 96%), however they are not 100% nor do they always hold up forever.
Additionally many patients actually have 2 or 3 seperate pathways, or abnormal locations that need to be ablated.
Its not uncommon for someone to get an ablation in say.. The left atria.. Only to come back in a few years with a new pathway causing problems in the right atria.
The decision to go ahead with an ablation requires an electrophysiologist to first actually verify your problem. For some rhythms ablation is the first treatment for others it's a last resort. Each case is unique and requires a special, taylor made treatment plan.
The other factor is whether or not YOU want an ablation. For many of these rhythms ablation is an elective option and you have the ability to manage the rhythm,with medicine or just ignore it entirely. How unfomfortable you are in terms of symptoms and what types of medical care you prefer to recieve is gonna be a major factor in building a plan that works for you.
