Hey, it's very nice to read your story, even though I only know a small piece it seems you and I will be able to relate a little bit. My boyfriend is Kenny and he is 27 years old and has also had 2 AVR's. With the 1st one he had a tissue valve and was only taking asprin however he suffered a stroke that led to a 2nd AVR and now has a mechanical valve and is on Warafrin. He too has had issues trying to get his INR on track, he has been as low as 1 and as high as 11! His 2nd OHS was done on Feb 10th, 2010 and his Dr's have told us several times that it takes a while to get your INR on track so we just have to keep a close eye on it, he too has had the dose changed several times so please don't worry about that part of it. Be cautious of grapefruit! I LOVE grapefruit juice and he cannot have it due to his meds and forgetting he was not supposed to have it drank some one day and it threw his INR # off quite a bit so please follow the items they told you to avoid! I really hope you get on track soon. What caused your initial surgery and why did you have to have a 2nd one? It's really hard to find people in our age group that have been through this so I hope you don't feel I am asking too many questions I am just doing a lot of research and trying to raise awareness.
Thanks
Stephanie
