Set aside his credentials for a moment and just put your thinking cap on. How could he claim that the new tissue valves will last 2x to 3x as long as the previous generation?
Here is the data. 5 years of human data for the Inspiris Resilia in the European arm and 5 years of human data in the US trial, known as The Commence Trial. Oh yeah, and there was 8 months of sheep data from a European trial before each of these trials. None of the above trials establishes that it will last 2x to 3x as long as the previous generation. In fact, they have not even established yet that it will last as long as the previous generation. There is "hope" that the new anti-calcification treatment will allow it to last longer, but at this point it is nothing more than hope.
Edwards, the manufacturer of the Resilia, does not claim that it will last 2x to 3x as long. They would face criminal charges of fraud if they did- and you better believe if there was evidence to support 2x to 3x as long that they would be shouting it from the mountains.
Your surgeon is very experienced. I really hope that he did not tell you that your valve will last 2x to 3x as long. That would be misinformation. I can't know this for sure, but I suspect that you heard him wrong. Perhaps he said the new valves should last 2 or 3 years longer than the previous generation and you heard what you wanted to hear. I sure hope that is the case, because it is very disturbing to me that a surgeon would be spreading such misinformation. Show me an article he has published on the subject that makes such a grand claim and I will believe that it came from him. Until then, maybe he really said it or maybe you just did not understand what he was communicating.
Yes, I am just a random nobody on the internet. But, I have read all the trials mentioned and, setting aside that maybe I am a dunce who can't understand anything, just use common sense please. How can one extrapolate 5 years of human data out 30-60 years? You can't.
But, if you want to talk about your surgeon as the final word because you are convinced that you heard him correct and that he really said 2x to 3x as long, I would challenge his position with the surgeon consultations that I had.
Let's just say for a moment that you are correct and that because you and I are not "doctors" that we really don't know anything, nor can we think critically. I would challenge what your surgeon ostensibly told you with what I was told by two of the top surgeons in the country. I consulted with the head of cardio thoracic surgery at Cedar Sinai and the head of cardio thoracic surgery at UCLA prior to my surgery and I specifically discussed the new generation tissue valves- the Edwards Inspiris Resilia. Both told me about the same thing; at my age of 53, expect to get about 10 years out of the valve and hope for a little longer, because maybe the new treatment will make it last a little longer. Both of these clinics are in the top 5 in the country.
So, if your surgeon really said that the new tissue valves will last 2x to 3x as long as the previous generation, and I am doubtful that he really did, he is wrong to suggest this without evidence. I am just a random internet guy, but the data is the data and I, too, have consulted with surgeons specifically about the valve in question and these surgeons gave me guidance in accordance with the evidence.
This is about making informed choices. I am not suggesting that you second guess your decision to go with a tissue valve, but if you did so with the belief that it will last 2x to 3x as long, so that you will never have to face a reoperation, well, I'd say you did not make an informed choice. But, you have the valve you have, so don't look back. We choose the valve that allows us to sleep at night. If you need to tell yourself that your valve is magic and will last 2x to 3x as long, then tell yourself that. But, if you present that misinformation here, this random internet guy will challenge the reasoning for your statement and ask you to support it with actual data. "My surgeon said so" Are you sure? Did he really say that or did you just hear what you wanted to hear?
And to be crystal clear, I am not advocating to not listen to your cardiologist or your surgeon. I personally had in depth discussions with both about the research and they were there with me at every step of the way in my decision process. But, if your surgeon is telling you something that sounds off- such as, "these new valves will last 2x to 3x as long" please ask him how he knows this and ask that he back it up with evidence. Be your own advocate, seeking a second opinion of what he tells you, if something does not sound right. If you are in your 40s and your "new" tissue valve only lasts 8-12 years, as would be expected, vs 40 years, it will be you facing a reoperation and not your surgeon. So, listen to your doctors, but at the end of the day, be your own advocate.
