Welcome to the forum Wendel!
Sorry to hear about your BAV condition, but glad that you found us. This forum has been an incredible blessing to me and I'm very glad that I found it before my aortic valve surgery. I had a Bentall Procedure 33 months ago, like you are now facing.
The surgeon suggested I do a Freestyle with a Dacron tube
I would like to know what you think of this election.
I'll be happy to give you my thoughts, per your request.
The guidelines for most of the world call for young and very young patients to get a mechanical valve if they are under 60 years old. 60 to 70 years old is the range in which either valve choice is considered reasonable and over 70 a tissue valve is recommended. I've linked an article below discussing biological vs mechanical valves for young patients. It is important to keep in mind what the heart valve community means when they use the term 'young' patients. Some mean patients under 60 or 70. In the article below, the term 'young' means under 70. When discussing patients in their 30s and 40s, the term 'very young' is used.
The guidelines are determined by the top experts in the field who rigorously pour over all of the data available on a medical practice. They are not arbitrary. But, they are not set in stone. Usually, the patient is the one who gets to choose the valve, regardless of age. It is a personal choice and only you can make that choice. Your surgeon and the members on this forum are not the ones facing either a lifetime on warfarin or future procedures. You are the one that will live with these realities and the choice is yours to make, as it should be.
If you said nothing else other than your age, assuming that you do not have contraindications to warfarin, I would suggest that you follow the guidelines and get a mechanical valve, in order to give you the best chance at having a normal life expectancy. However, you did provide some key additional information, which in my view tilts the scales towards the direction which you seem to already be leaning towards.
You said the following:
I have generalized anxiety syndrome and I think that the “click” of the valve would be very annoying for my mental health
As well as:
I am a psychiatric patient and the “clicks” would be unbearable to me,
Now, if you had come here and asked us folks living with a mechanical valve whether the 'clicking' bothers us, I would give you my personal feedback that it has not bothered me and direct you to the several threads we have here discussing this topic. The reality is that the vast majority with a mechanical valve are not bothered by the sound. Personally, I rarely hear mine and have never been bothered when I do. But, you did not ask this question and rather seem to have indicated that you have already decided that it "will" be unbearable for you. I believe my cardiologist got it right when he indicated that in his experience, in following up with hundreds of valve patients, that being bothered by the sound is psychological. I believe he mentioned that only one of his patients expressed regretting getting a mechanical valve because of the sound it makes. It would seem that his anecdotal experience with his patients is in alignment with the members of this forum who have mechanical valves. In fact, I don't recall any member here indicating that they wish that they had chosen a tissue valve, due to the sound.
But, our experience is our experience. You know yourself far better than any of us could ever hope to. In my view, there is an element of self fulfilling prophecy in such issues which are largely psychological. If you have already decided that the "clicking" will be unbearable, then it likely will be for you. It is for this reason that, in my view, you are leaning towards the correct decision for you.
Surely in the future I will have to have reoperation, but in the meantime he has said to “look forward and live life”, that these valves can last between 15 and 20 years.
I do believe that you are making the right decision, but I have to take issue with the guidance that you have been given as to expectations for how long your valve will last. I had consults with two different surgeons prior to my surgery. Both the heads of their departments, one UCLA the other Cedar Sinai, which are among the top valve centers in the US. They both told me about the same- to expect about 10 years from a tissue valve. Keep in mind that I was not 38, but 52 at the time. The younger a patient is, the quicker they go through tissue valves. I am not aware of any study which indicates that a 'very young' patient in their 30s can expect 15 to 20 years. I'll comment further on this after quoting you again below:
I have read on the Internet that they can last 10 years, but most of the studies are old and with patients older than me.
True, that most of the studies involve patients much older than you, but it is very well established that younger patients go through tissue valves much faster than older patients. If you read some of the threads here, you will see that many patients who chose a tissue valve in their 30s and 40s had to get reoperations after 5 to 12 years. Very often it seems to be less than 10 years if the patient is under 40.
I really don't know if the valve lasting 15 to 20 years is key to your decision. If you knew that the limited evidence that we have would suggest that you should probably expect only 5 to 12 years from your valve, would that change your decision? If the answer is 'no', then it does not matter which expectation is correct. Go in the direction that you are leaning. If your answer is that 'yes' such a short-term expectancy for your valve would influence your valve choice, then, rather than trust me or other 'random' internet people here, please seek a second opinion on the expected valve life for you. This is a major decision and you should not trust a bunch of 'randoms'. If you do seek a second opinion on this matter and you get the same guidance, to expect 15 to 20 years, even though you are only 38, it would be great if your consultant could provide you with the study which he is basing this expectation on and it would be much appreciated if you could, in turn, share it here on our forum. Although, I can almost assure you that there is no such study. I would love it if you are able to prove me wrong about that. The two long term studies I was able to locate on the Medronic Freestyle had average patient ages of 69 and 75. This data can not be relied upon for a 38 year old patient.
Again, the expected valve life is probably a moot point, as you have determined that the clicking will be unbearable. But, for the sake of informed decision making, I wanted to address what I believe to be an overly optimistic expectation which you seem to have for tissue valve life for someone your age, so that in the event it does matter to you, you can seek additional consultations on tissue valve life durability expectations.
Below please find the article which I mentioned above. Some key points, including one which is consistent with the trend you mentioned:
"The use of biological valves for surgical AVR is steadily increasing, but there are limited data addressing potential differences in outcomes between biological and mechanical valves for the procedure, particularly in younger patients with a longer life expectancy."
"Indeed, the growing use of biological valves in younger patients, said Witberg, is proceeding without any clinical evidence supporting their use."

Regardless of which valve you end up choosing, the community his here to support you.
Pleaes feel free to ask any questions which you have and wishing you the very best of luck with your operation.
