Because of the tissue valve, I was only on Coumadin for three months but my husband and I were completely exasperated with the incompetencies (or whatever) we saw with the labs! There was also a power struggle between my local primary physician and the cardiology office (over two hours away) as to who would monitor and treat it. And the local nurse would say, yes she knew how important it was to get the results immediately, but one week I waited four days for results (and I called them repeatedly to chase down the results!). More than half the time my INR was plus or minus 1.5 when it was supposed to be 2.5-3. Finally the local doctor said that if I wanted the cardiologist to monitor it I would have to drive to a further town to the nearest hospital lab to get it tested. My veins are tiny and deep also so getting poked repeatedly was unpleasant and the hospital lab would leave huge knots in my inner elbow area and then blow up veins on the top of my hand. Plus, early on, there was the one quart a day of fluid situation...trying to get blood out of a dried up raisin...
AM I WHINING?!?! (sorry - I know these are things you've all been through)
If and when I end up with a mechanical valve, I hope we can buy the machine and monitor it ourselves!
