When I looked into this recently, I discovered that there has been considerable progress made in the last ten years on treating VT's through catheter ablation. But make no mistake, there are definitely risks.
Idiopathic VT's generally fall into one subtype or another and the prevalence of each type in the general population is pretty much known. Most of the common idiopathic types have corresponding ablation strategies that carry high success rate. There is a small number of people who have a type for which an ablation strategy exists, but for which the risk is high and the ablation strategy no so straight forward.
If your VT falls into one of the more simple types, and your doctors agree, i think it is reasonable to weigh the risk of an ablation against the effect the VT has on you. However, if I had a VT that originated at the base of the papillary muscle for instance, and it could only be treated by the use of, say, a large cooled tip catheter, unless the symptoms are very very bad, and could cause me to die without treatment, I definitely think I would pass on this type of ablation. The risks are too great, but for someone who is practically ready to check out.
But if it is not like this, and the type of ablation I need is a "light duty" ablation, then this is where I personally struggle with my own VT, because here it is now safe enough to consider, if I am something of a daredevil. Here I have a reasonable chance of success and a respectable, low risk, i.e. only about 1% at a respectable health institution of having something really bad happen. Is it worth suffering through some benign symptoms, or should I take that 1% chance that I could be hurt very badly, and take the 90 or 95% chance that I may be free of my VT in exchange for it.
Well, this is a very personal choice. And it is a choice that can really change you for good or bad. Just be careful, and take your time in deciding. For me, it is just really important to have a good perspective on how things work, what the potential pitfalls are, and so on. I have talked to numerous people about this to get all of the ideas, and advocate that others do this type of thing too. Remember, life is very very special.
One other major factor to consider is whether your VT is a light duty VT on the right side of you heart. Here the risks may be even lower than on the left side.
Ultimately, you will need to ask your doctor for information about your risks. It is then definitely worth thinking things through.
I need to c larify something. I am not a doctor, and what I just said may not apply to you directly. Be sure to question everything I just said, and talk to your doctor about your options and risks.
Best of luck.
