That's really disappointing, Smackman. I know exactly how you feel. I had counted on being off blood thinners as well.
The first TEE was good and encouraging, but Dr. Natale wanted me to wait 6 months and have another. That was borderline and came with the strong suggestion I remain on it....undoubtedly, because of my age... and I understand that and the risks involved. Still, it doesn't manage my emotions about staying on a drug for life and as you mention the cost factor.
In the grand scheme of things, though, it could be a lot worse so I have been attempting to come to grips with it.
My best to you,
Jackie
