The key to the whole thing is the first paragraph. They are talking about patients age 70 and above for tissue. 60 and below for mechanical. In your 60’s could go either way. At age 70 plus, the bullet points you cite are accurate. Fairly consistent with what many on this forum have been saying for a long time.For anyone making their decision between biological and tissue, this article has good information on the pro biological valve option/choice.
Biological Vs Mechanical Valves – Key Points
I hope this helps anyone deciding valve choice is best for them.
- Long-term survival is equivalent
- Mid-term morbidity is worse with mechanical valves
- Reoperation rates are low with biological valves and are not insignificant with mechanical valves
- Reoperative aortic valve replacement has similar mortality to primary valve replacement
- Complications of mechanical prosthesis are more devastating than those of biological valves
- Mechanical valves can have substantial negative impact on daily quality of life

Disregard. It opens with conventional wisdom, then goes on to make the case for under 70. Still, it focuses on operation age at roughly 60. Being 48 and ticking for over 30 years already, I have a hard time relating to many or really any normal studies.
