Hi Allan,
Thanks for your courage in bringing up this topic and sharing your vulnerabilities with us.
I think whether you regret your valve or not depends on how you're doing with it at a given time. I'm sure most of those with no problems are not having any regrets whatsoever, as some of the previous comments here attest.
I had no problems, indeed superb results, for 8 months post-op, and certainly did not regret my choice in the least, even if it was a less time-tested valve than most. Then, they found out it was leaking, but I still had no symptoms and no regrets. Then, they put me on meds that were making me faint and limiting my physical exertion, and then I did begin to have regrets. Then, they told me I would need to replace it again in the not to distant future, and then I had a lot of regrets! Then, they got the meds straightened out and I was relatively back to 'normal'. My regrets decreased. Now, about 1 year post-op, they say that my heart size is again decreasing and heart function improving, and that I may not need surgery again for some years. My regrets have decreased even further, though I still have some for sure. Although many VR veterans have few problems post-op, it's not that unusual for some to take a while to adjust or even need to undergo further surgery. In my case, I've experienced both.
So, I think it is wrong to consider this as primarily a valve choice issue. There are plenty of examples of all kinds of valves going wrong. If we make an informed choice of what valve suits us best, if it works as it is supposed to, then we have made the right choice. If it turns out not to work as it is supposed to, then that's a different matter.
I actually have no regrets whatsoever for my valve choice and might very well choose it again if and when I need to. The problem is not that this kind of valve never works as it is supposed to, but that, in some few cases, it hasn't. Plenty of mechanical valves have had to be replaced for leaks or infection or even structural failure; that doesn't mean they are a bad choice unless the incidence of problems was truly more than it is.
Even with something as new as the SynerGraft, most recipients have not had problems in the short-term. Of course, the long-term problem rate is not yet known but the short-term rate is, and it seems to be a very good one at that (at least in the US). My leak is evidently one of very few short-term problems at this point, and so I don't think I'm warranted to blame it upon the kind of valve, but rather upon the particular valve (or surgical treatment) I received. Similarly, if I were to have chosen a mechanical valve and have been one of the few to have problems with it, I would not regret my choice but rather the unfortunate but less common outcome that the particular valve or surgical treatment I received did not turn out the way it usually does.
In any case, we should consider the outcomes of others, both statistical and anecdotal, before making our valve choices but always remember that every choice involves a relative amount of risk. I chose a bit more risk than most but not all that much more. It's not like there was no track record to go on. CryoValve's in general have an excellent and long-term track record and the SynerGraft treated valves have had impressive short-term results, though, of course, not in all cases.
I believe that this discussion is particularly relevant for those who have had some problems with their valves and would like to hear more from more of them in this thread. It's not that it's not also valuable to hear from those who haven't had problems, but I think the tendency there will naturally be to say that their choice was perfectly fine, even though that is not a whole lot of solace to those of us, such as Allan and I, who are having problems.
Allan, I hope things get better for you. We have made our choices and have to live with them. I don't think we should change our valves if we don't absolutely have to, but, if and when we do have to, we certainly have to reconsider our previous valve choice very seriously.
All the best and God bless!
