Very unusual for a tissue valve to last 20 years.
It is probably badly deteriorated and not good for the heart
Must be replaced with a mechanical valve that allows minimum dose of
anticoagulant. The On-X valve is technically today the more advanced valve design. The last generation of tissue valve may last for another 20 years. If you are in AF anyway you need anticoagulation and the mechanical option is better.

No, it's not unusual any more. In people 60 and over, the last generation of bovine tissue valves is averaging over 20 years. And that's without the new anticalcification treatments or the new non-damaging fixation methods.
She's 70. Unless there is a reason why she would need to be on ACT (other than the valve), there just isn't a reason she shouldn't go find someone else to do the surgery the way she wants it. In the absence of other illnesses, there's just no compelling reason to replace it with a mechanical valve, unless she so desires.
Best wishes,

Best wishes,
When did the latest generation of anti-calcification bovine valves come into our hearts? I am wondering if mine from a year ago was of that generation. And what is the new non-damaging fixation methods and when did this start?
THANKS!

Glenda,
I'm curious about what KIND of Tissue Valve you received.
There is a Big Difference between the Bovine Pericardial Tissue Valves and the Procine based Tissue Valves.
The Bovine Valves have a proven record of longevity approaching 20 years when in implanted in more 'elderly' patients (age 60 or more).
The Porcine Tissue Valves typically have better performance when it comes to the Gradient across the valve and is often the choice of more athletic types.
The 'new and improved' Porcine Tissue valves are hoped to have better longevity but haven't been around long enough to know for sure.
Pannus Tissue Growth around where the valve was sewn in is the 'enemy' of longevity and is probably more patient related than valve related. It can happen with BOTH Tissue and the older Mechanical Valves. To the best of my knowledge, only the On-X (mechanical) valve has a barrier to prevent / retard Pannus Tissue Growth.

My medtronic freestyle aortic root is a 3rd generation bioprosthetic porcine valve with AOA treatment and zero pressure physiologic fixation. This is outlined at the Medtronic website http://www.medtronic.com/cardsurgery/products/free_advtechn.html.
The newest surgical guidelines have been adapted to reflect the new longevity of these valves and offers the hope of ACT free lives to younger patients.
