Hi Andy and welcome to the forum.
I feel you and I have many similarities.
At age 52 I got hit with multiple diagnosis, with the tests following up on a murmur. All genetic. Bicuspid valve, aortic stenosis, moderate and sky high Lp(a), a genetic blood lipid associated with significantly higher risk of cardiovascular disease. I felt like I won the lottery, but not the good one.
I have a recently discovered a 2-for-1 5.7cm ascending aortic aneurism
Apparently my valve is ok with only mild regurgitation.
My situation was similar, but it was my valve that eventually reached severe and needed replacement. My aneurysm was not even close to the guidelines for needing replacement. However, after two consults, my surgeon knew that I desired to be one and done. When he got his eyes on my aorta, even though it was only 3.5cm, he made a judgement call. In his opinion it visually appeared to be under stress and he estimated that it would continue to enlarge and need repair one day. After 10,000+ valve surgeries he says that he can generally tell by the appearance of the tissue. So, even though the guidelines did not yet call for aneurysm repair, he replaced my aortic rood and part of my ascending aorta with a Dacron sleeve, so my procedure ended up being a Bentall. I don't want to have another OHS down the road, so in my opinion he made the right judgement call.
It is not an easy decision, but it is reasonable to consider replacing your valve while they are in there doing your aneurysm, but only if you plan to go mechanical. As this will drastically reduce the chances of needing another OHS. If you plan to go tissue when the time comes, then I think that it creates an additional argument to wait on the valve, as they will need to go in again anyway at some point. But still a tough choice. Perhaps your valve survives long enough to the point where the guidelines would recommend a tissue valve. But, if it lasts only 5 years or so, then that's OHS #2, with #3 likely following at some point down the road, especially since you would still be young when you are getting #2. Will you be eligible for TAVR on #3, maybe, but in my view this is best suited for the high risk patients who are not well enough to face OHS, given that at 5 years TAVR has a higher mortality than SAVR, so what is gained by TAVR for the younger patient, and in this case I mean <80, other than a quicker recovery?
I read somewhere that 70% need replacing at some point
Which, in my view, makes a strong case for replacing it while they are in there, especially if you plan to go mechanical.
does anybody have intel on the durability of the inspira resilient valve post 5 years?
Published data on this does not exist. The Commence Trial stopped at 5 years, as well as the smaller EU study. If you decide to hold off on replacing your valve, there will be better long term data on the Resilia by 2027-2029. If your team believes that your valve can make it this long, this adds to the argument to wait. Who knows, maybe the Resilia ends up being so good that it can take you all the way to the end if you get it in your 60s. But, at the moment we just don't know.
Seems a bit of a leap of faith to hope for 20 years from it followed by a TAVR with another 20 years (takes me to 91
I totally agree with you. There are at least a couple of surgeons out there telling young folks that they will get 20+ years or 30+ years out of the Resilia, without any evidence to support this. So, it is a leap of faith. It might last you 20 years. There are even two members of this forum who had tissue valves done at relatively young ages who are at about 17 years out now, so the Resilia could very well do even better. But, I would estimate that there are 10x as many members here who had to get their tissue valves replaced in less than 12 years. Some much faster than that. So, it comes down to whether you feel lucky and believe that you will be one of those individuals who survive a long time without SVD with a tissue valve and believe that the Resilia valve will end up being superior. Alternatively, you could go with a mechanical valve that will likely last you the rest of your life and then deal with a lifetime of taking warfarin.
And, I also agree with you that expecting to be able to get a TAVR down the road and believing that it will last 20 years is also a leap of faith. You may or may not be a candidate for TAVR. Most native bicuspid valves are not good candidates. I was evaluated and it was determined that I was not eligible. If you do qualify for TAVR it would be extreme optimism to expect to last 20 years. I'm not saying that it is entirely impossible- you could put all your money on the 00 green space at Roulette and win big, but just don't bank on it.
Not keen on a second OHS and the associated risks, but not keen on warfaren either. I have an active lifestyle with mt biking and skiing and kayaking.
I ended up choosing mechanical at age 53 and have been on warfarin for 15 months. For me it is no big deal and I am very physically active. I see no reason why you would not be able to mountain bike, ski and kayak, although I think some caution on the bike downhill would be warranted. I just came from my nightly jiu jitsu class where I grappled with others for 90 minutes. There are a few activities which should be avoided, like boxing or tackle football, but those of us on warfarin will tell you that the idea that you can't lead an active life is a myth.
You have some big choices ahead of you. Personally, I would probably opt to get the valve replaced while they are in there with the hood open. And I would consider a mechanical valve to be one and done. But, you are not me. If you choose to just do the aneurysm repair only now and cross your fingers that you will not need another OHS, it would not be an unreasonable decision, and clearly your medical team feels this is the right path. But, most BV patients eventually need their valve replaced and should your valve need replacing in 5 or 10 years, remember that it is you who will be facing this, not your team. It is your decision and you live with the consequences.
I would keep getting opinions from medical professionals and keep asking questions here on the forum. I would also discuss the matter with family. You face some challenging decisions, but you are approaching it the correct way and asking good questions.
Best of luck in whichever decision that you make, both on whether to get the valve replaced along with the aneurysm repair and also in your decision about which valve to choose, if and when that time comes.
