When I lean towards the mechanical valve in my analysis, I try to think of being at that point in 7 years or 10 years when they tell me on an echo that my biological valve has started to deteriorate and they need to start doing more frequent echos. If I go biological, I can really see regretting that I did not go mechanical once I get to that point. In the short term, the biological valve has a lot of appeal- don't need to give up any of your activities, don't need to manage warfarin, nor worry too much if you bump your head and get a bump. The video presentation that Edwards has on YouTube with the three surgeons discussing their research on the Resilia is very interesting and certainly gives the impression that this valve is likely to last a long time. One of the surgeons presented their findings on one of their studies on the Edwards Perimount valve- over 50% of these biological valves did not need reoperation- at 20 years. That is remarkable and it gives hope that the next generation, the Resilia, will last even longer. But, when you actually read the study that he is discussing, I find the actual data much less compelling for biological. What they don't tell you in the presentation, which is really more of an infomercial for the Resilia, is that after 20 years about 80% of the patients had died. Looked at another way, patients had something like 12% probably of being alive at 20 years and without a reoperation. The vast majority died before they needed a second operation. Again, remember this is not the Resilia but its predecessor. And keep in mind, the average age was 71 years old- with many under 60 but some as old as in their 90s. So, of course anyone 80+ will not be alive in 20 years. Take an 80 year old SAVR patient who dies at age 88. I find it a little misleading at 20 years to count his valve as one of the ones that was free of reoperation- of course it was- he died 8 years into the study.After just going thru this process ( a second time) and on the post operative side healing, I am seeing things much clearer. Simply put, there is no way I could intentionally plan to put myself thru this process again in approx 10 years. And remember you lose around a year with increasing symptoms and anxiety prior to surgery (6 months) and 6 months recovery to full strength. I'd currently be in a deep depression if I had chosen a tissue valve. Again, to me, mechanical is the most logical choice. Allowing surgeon with much experience to determine if SJM or On-X is best for your specific anatomy.
And consider do you have any idea what your insurance coverage will be in 10 years, and costs rise every year.
All just my opinion. Good luck!
So, while it is clearly true that at 70 years old, a biological valve is probably going to outlive the patient, younger patients are still most likely facing reoperation due to SVD, should they be fortunate to live a normal life span.
To follow up on my comment that the video presentation is like an infomercial, I don't totally fault them for this. They are putting millions into valve development and this clearly is to the benefit of all of us here. They have to let folks know about their products. It just feels a little funny to me see the surgeons, who, as I understand it, make very large sums of money to run these trials, present the data as if they are spokespeople for the valve companies and present the data that seems to sometimes be misleading. This is where we have to either really look deep into the studies ourselves or rely heavily on our medical team to tell us what is best for us, and preferable do both.
