Hi, my 30-yr-old husband received 2 bovine valve's in 97' and has been on daily coumadin ever since. He also takes digoxin, and atenolol. I am curious if anyone knows why coumadin therapy is required after valve replacement? I assume it depends on the individual history, but would think after valve replacement, that blood would be following better, thus not needing coumadin?
Thanks so much.
