Good morning Martin
I see your valve was done in 2012 (about when mine was) and you joined back in 2016. So I know you're not a newbie
I'll assume that this was sort of a reply to my question
My body was reacting to something on the new valve and started putting blood on the leaflets causing them to thicken.
this sounds like thrombosis was forming ...which is a bad thing and one or both of these may happen
- the valve will clag up and not operate properly (I understand its a tissue prosthesis and in the mitral position right?)
- lumps of thrombosis can break off and lodge where they shouldn't be blocking blood. This is similar to what DVT does (a clot lodges in a place) or a stroke does.
It took about 6 weeks for the leaflets to stop moving from when I stopped warfarin post-OHS. It's a slow process.
err ... I hope you mean thickening ... the leaflets should still be moving
My range is 2-3 and highest it's ever been in 9 years is 3.2. I'm not worried since I'm fairly stable and mostly below 2.5. I'm consistent with my diet with relation to greens etc. that can affect INR.
well I guess that's good ... but even the veterans here who have stable INR's (and test weekly) will tell you that occasionally there will be a spike for no explanation whatsoever. They adjust and move on.
I did have a change in INR after losing 15 lbs last year. It was lower. They added 1.5 mg a week to my dose. Total dose per week is 28.5 mg.
I see you're dealing with a very old school clinic that still thinks in your total weekly dose. That's actually pretty meaningless not least because you don't take that dose once per week. You take your dose once per day. The decimal in there is even funnier because that means a difference day to day of 0.07mg on a tablet which typically comes in 1mg being the smallest dose, and half a tablet is 0.5 ... something like ten times more than 0.07mg
I'm sure these nutbags think that by talking precision numbers like this to you that you will unconsciously get the impression that they have a clue. Usually they don't.
So your daily dose is 4mg (lets come back to that)
My biggest problem is when I have a surgical procedure. I can't seem to get a doctor to tell me when to stop warfarin.
this is not uncommon and while we all graciously endow the priests in the doctors seat with a presumption of knowledge its often entirely absent (or worse, misinformed). The best way to be entirely sure is "
Test and Know Thyself"
Off the top of my head I would say that if you cease warfarin for 4 days that by the time surgery is ready you'll be able to be operated on with an INR of about 1.4 (more or less depends on your particulars which can only be known by measureing).
Here is my last two responses to procedures written up, on the colonoscopy I was more concerned about potentials for bleeds because a friend nearly died from a major bleed just months before mine AND he wasn't on warfarin

and on a toe surgery:

which was less concerning because on limb extremities they block blood flow with a pneumatic pressure device (aka a fat tourniquet sleve)
I had some fatty lumps removed and couldn't get anyone to tell me what to do. I finally followed what my gastro doc had me do before a colonoscopy.
No AF or DVT problems here.
Excellent, but that thrombosis on the leaflets is still a concern. An old view here is that blood cells can be replaced more simply than brain cells.
Strokes are permanent and not to be messed with. Meaning that your dose of warfarin is every bit as important as anyone elses.
The stats are what they are for risk, and we know that they are improved to nearly zero (actually the general poulation age related risk) by increasing time inside the therapeutic range to 100%
I have not had a car or motorcycle accident of any nature for many years now (over 30), I've put 40,000km on my motorcycle in the last 3 years and my car (that I've had since 2003) over 300,000km,
but I still put on a seatbelt and wear a helmet.
Upped the dose by 1.5 mg per week. I take 3 mg on 2 days and 4.5 mg on the other 5 days. It was 3 and 4 before that. So dose went from 27 to 28.5 mg per week.
I love these quaint quasi formula that they give you. Firstly the dose of 4.5 is 50% higher than 3 ... what the actual F?
Secondly the half life of warfarin is (around) 48 hours ... so the dose you took at the beginning of the week is all but nothing within 5 days.
I think I stopped warfarin 3 days before procedure and then went back on after it. Would have to look up my notes to be sure.
that's close to what I said above
Most of my INR variations are due to testing after a 3 mg dose day vs. 4.5 mg dose day.
that's an assumption and really you have nothing to back it up, but if you already know that why the hell do you continue having a ZigZag dose?
Anyway, if you are interested (
I write as if you are, but I know most aren't) in better managing your INR I'd start with my blog here (which is quite detailed):

and an interesting publication by a medically recognised INR expert here (

I guess it varies on the personality type, but if you are interested in the best health outcomes for yourself then you need to be active in doing and aware of what to do. Beware of fluff and nonsense in the advice you receive and always ask "why".
Best Wishes
