Interesting discussion. My surgeon wants to use the ON-X, but not for the potential lower INR. He is recommending a long-term INR of around 2.0 +. He likes the way the ON-X valve attaches. He believes there is less chance of future calcification around the stiches. Has anyone else heard this reason? It may just be his preference. For me, if he has more experience and prefers the surgery with the ON-X, then that is a pretty good reason.
