OnX was developed by the same guys that designed st jude, so, if anything , OnX is a better St Jude
DUE TO the fact that:
OnX is the only mech valve that the leafs open 90 degrees,,,, and from there is the fact that it is
a better st jude,
the inr range, is not the issue, both work well at 2.0
That’s the claim. Seems adverse outcomes would be the true measure. Is there any comparative study on the various mechanical valves showing that any of them (assuming a well managed INR) has higher incidence of negative outcomes or improved physical performance by patients after installation?
I get that On-X couldn’t come into the market and say, “We’re just as good as the established product, give us a try!” So they have to create ways that they’re “better”. But are they? I’m not saying they’re worse. I just haven’t seen anything that says a persons post operative experience will be different in any meaningful way.
