Hello and welcome to HealingWell. We don't get to many members with WPW but I do hope that someone with experience will come along and have input for you.
I can understand your fears and I do wish you had a physician that had a better bedside manner. Is there another medical professional available that could help you out with your questions.
I wish you well and hope your procedure is a success. From the information I have read when performed by experienced specialists, ablation cures the WPW syndrome over 95 percent of the time.
