I require AVR + Ascending Aorta replacement + possible root (They all said they will see once the bonnet is open). I have spoken to three surgeons and had three answers. 1. Definitely Mechanical at your age (50y) 2. Latest generation Tissue with future TAVRx2 possible or 3. What ever you want I'll fit. The fundamental question is Mechanical or Tissue. The options as best I can tell are: Mechancal: St Judes, Carbomedics or On-X. Tissue appears to be the Edwards Resilia Valve.
I know this is a very emotive and well trodden issue so I am trying to apply some logic to it.
Somewhat frustratingly I don't think this will be a question in ten years time for people as I would guess the Polymer valve technologies in the pipeline will hopefully provide lifetime durability with no Anticoagulant requirements. Several universities are even looking at 3d Stem Cell printed bio valves. I'm sure the future will be nanobots that just go in and repair your native valve ;-)
We are similar in age, I'm 53 and am facing both the question of getting the surgery now, while I am asymptomatic or waiting for symptoms, and also mechanical valve or biological. I will share with you my thought process on the subject, which way I have leaned and which way I am leaning now.
Originally, after watching a long presentation regarding the Edwards Resilia, and how it looked promising for delaying calcification and SVD (structural valve deterioration), I read up on everything I could on the Resilia. I leaned heavily towards getting a Resilia biological valve for the following reeasons:
-I'm very active in combat sports, which would be totally out, except going light, if I choose mechanical, as I would be on warfarin. The nice thing about a biological valve is that, most likely, I would be able to resume all of my hard core contact activities
-I researched about rehospitalizations from warfarin and this was very concerning. One study found an annual risk of hospitalization from bleeding due to warfarin at 4% per year- that is 40% chance in the next decade and this really deterred me
-Biological valves are expected to last about 10 years for people our age, but there is hope that the Edwards Resilia may last longer, due to the anti-calcification treatment
-Long term survivability is claimed to be the same regardless of valve choice.
I would say that I had about 90% made up my mind to go this way. But, I have shifted my view for the following reasons:
-Having listened to many share their warfarin experiences I think that there are many misconceptions about it. While certain activities would be out, people can live very active lives.
-The numbers for rehospitalizations drop drastically, if you self manage your INR and if you keep taking your medication. One study found that about 50% of people who are prescribed warfarin stop taking it- which Pellicle has linked recently in another thread. There was another study published that found rehospitalizations for bleeding about the same for mechanical and biological for those who carefully control their INR. Another study, again thanks to Pellicle, showed that the vast majority of bleeding events happen at INR on the high end out of range and the vast majority of clots happen at the low end, out of ideal INR range- one has to wonder how many of those stopped taking their medications altogether.
-I don't agree that long term outcomes are the same. The evidence seems to suggest that mechanical valves have better long term outcomes. Take a listen to this presentation by Dr. Hertzell Schaff of the Mayo Clinic- again, thank you Pellicle.
- While there is hope that the Resilia will last longer, I can't base my decision on hope. There are only 5 year outcomes published so far on the Resilia and without additional evidence, I have to assume it will only last 10 years. This is standard for biological valves in patients my age, and for some people under 60 they only lasts 6-9 years.
- I have no problem testing weekly and even daily to self monitor INR. I am the type that likes to graph my health metrics and could see myself being diligent about this.
-I would still be able to do many of my thrill seeking activities and look forward to adding more
-I want to see my kids grow up and my grandkids too. I don't want repeat surgeries.
- Playing out the numbers for future surgeries, it does not look good once you get to the third if you go biological. SAVR at 53, then valve in valve TAVR at about 63. The hope is that the TAVR will last 10 years, which is certainly not known, esp for younger patients. Then, if I do manage to get 10 years out of TAVR at age 73, I am now facing TAVR in TAVR, which at this point is valve in valve in valve. That's a lot of junk in the valve space point there and the AVA is now just a small opening. It is probably like starting out after surgery with moderate stenosis. How long will that second TAVR last? Unknown. What complications? How active will I be able to be at that point?
Before anyone thinks that having a valve in valve in valve at a relatively young age is a good idea, please listen to this talk between Lars Svensson and Doug Johnson of the Cleveland Clinic. Lars cautions about people in their 40s and 50s getting biological valves with the plan to go TAVR on the second one, which he says will complicate things going into a third operation. He believes those in 40s or 50s are better off going SAVR then SAVR before going TAVR. Having talked to my cardiologist about TAVR in TAVR, to me that is something that I personally want to avoid unless I was 85+ or so. At 73, I plan to be very active and really don't like the idea of TAVR in TAVR. If either of my first valves don't last the expected 10 years, I could be facing the third operation at even younger than 73.
Listen to this talk, and if you want to jump right to the comments by Lars Svensson in this regard jump to 8:30 point in the video. BTW, Lars is one of the most highly regarded surgeons out there:
So, at this point I am now leaning about 90% mechanical as my choice and may yet shift again. I am going in for a consult in a couple hours with my surgeon. He was a consultant to Edwards for the Resilia valve, and I expect he may come up with some good arguments why I might want to consider it again.
