First, find a cardiologist whom you trust and can easily discuss EVERYTHING. My husband was in a situation similar to yours; I'm an RN and accompanied him to everything. After 2 scary hospitalizations, endless testing, recommendations, certain suggestions he did NOT want to follow… We decided on ablation. It is a very common established procedure, and very low risk in the hands of an experienced interventional cardiologist. Don't be afraid to ask the doctor about his complication rate, experience, alternatives to ablation, etc. For example, my husband did NOT want an ICD, but he also didn't want any more adenosine.
The procedure went very well, and he's been symptom free since that very day! Keep in mind: you'll need to be on a blood thinner for a while, the procedure is typically done under general anesthesia, be certain you get a clear picture of the risks and benefits of both the procedure and the anesthesia, and that you'll need pre- and post-procedure testing and follow up. He is doing great, and we're very happy with our decision.
