From that
Also new to the guidelines is the option for people as young as 50 who require surgery to replace a diseased aortic or mitral valve to receive a valve made of natural animal tissue as opposed to a mechanical valve made of artificial materials. Previous guidelines said patients had to be at least 60 to receive a tissue valve.
Mechanical heart valves typically don’t need to be replaced and were previously recommended for younger patients who needed a valve that could last decades. But mechanical valves require a lifetime of taking the blood thinner warfarin, known by the brand name Coumadin.
Although warfarin is inexpensive, it requires frequent blood tests, dietary restrictions and possibly limiting physical activity, Otto said.
I think they are calling 50 "younger", which is in line with the fact that for the
vast majority of surgeries the idea that the patient is under 40 is as likely as they are martian. I had my second valve replacement at 28 years old.

Due to demographic changes in average life expectancy, the age of patients undergoing cardiac surgery is increasing as well.
So they are saying leather is a natural product. Seems very disingenuous for a organisation of their stature.
Once upon a time, car drive shafts were joined to the diff by leather. it wore out fast but they didnt mind and ther owners could afford the costs of maintenance. Now we use steel.
The problems with warfarin come from its requirements for frequent blood testing. Once that meant lab tests and vein draws, now it's as simple as a finger prick. I think that has not sunk in. To most surgeons yet.
The dietary restrictions myth still perpuates...
If you are younger (which to me is under 40) then ypi need to identify what your risk of aneurysm is. For this may ultimately drive your next surgery requirement. And ultimately among the most important pieces of information in the puzzle of making your decisions
always remember: when reading what others have written and published "
what questions were they answering" and juxtapose that with "
what question are you seeking answers for". Then you can read between the lines with greater clarity, for its seldom that an author is writing to you (except when directly answering
your questions)
