Coarctation of Aorta 29 years old

Hi, I am new to this forum.  I was just diagnosed with coarctation and had bypass surgery to replace my aorta over the summer at the U. of Penn.  Since then I have been getting different responses to some of my questions.  Prior to the surgery I had a healthy pregnancy, I was told it would not be a problem after the surgery but I have to be on Topral which has a pregnancy category C rating, so I am not sure what that means considering it has not been studied in this group.  Also I was told that my biscupid valve needs to be replaced in ten years.  Considering this birth defect should have most likely been diagnosed before the age of ten what does that mean for me in the long run considering I just had the surgery.  This has been overwhelming and I just want to make sure that I as informed as possible about pregnancy, my future and so forth.

Thank you very much for your time.
