As a woman who knew I'd eventually be having valve replacement from the age of 14 on, and who made the decision at 28 and again at 30 to get pregnant before the replacement, even though it could have ended with an early baby and me in the OR, I know that. I just hope the surgeon told her that the life of the tissue valve after going through two pregnancies would be significantly affected. As my cardiologist said, "A pregnancy is like a 9-month long game of basketball where your heart doesn't get much time to rest."
