Lisa , you are correct about educating yourself in these matters , I have been talking with any and all specialist I can in this matter . But most of them are unaware of RSD , imagine that , right ? I would feel pretty comfortable with the surgery now if it wasn't for the RSD because I would like to do it while I was younger but at the same time if I have to go with the artificial valve I certainly do not want to have this surgery a couple of times...I am 49 now . Which valve did your father go with if you do not mind me asking ? Take care !
