mamarobn, Hi. I have Ebstein's as well and have had my tricuspid valve replaced. Lyn sent me a message about your other thread on here, but I've been out of town and haven't been able to post. You didn't say who your surgeon was that you are talking to, but I would highly recommend you seek out someone who has had a lot of experience with EA and there aren't very many of them. There is a procedure called the cone procedure that can save the valve in a lot of patients. I didn't have enough tissue to have this done, hence the replacement. However, I would do every thing I can if I were you to spare that valve if possible. The two most experienced surgeons who are doing the cone are Dr. Dearani at the Mayo in Rochester and Dr. Pedro Del Nido at Boston's Children's Hospital.
If you have to go have it replaced, the people who have the most experience usually recommend tissue. A mechanical valve on the right side of your heart is more likely to clot, hence a higher INR has to be maintained. I do know of one woman who Dr. Dearani operated on who he finally put a mechanical in her right side after she had 3 surgeries in a very short time period and already had gone through 1 mechanical valve in 2 years in her aortic position. She is now having problems with the 2 mechanical valves destroying her red blood cells and has to have blood transfusions frequently. I will say this is a rare side effect I think.
I have had my tissue valve now for 3 years. I was 45 when I got it. Dr. Dearani told me that I would hopefully get 12+ years out of this first one and then get more out of each additional one. To my knowledge, tricuspid valves are not being replaced any other way than by traditional OHS at this time. Especially the first one, they will have to reposition the valve to it's correct position.
If I can answer any more questions for you, feel free to ask. Good luck.
