Monica,
Welcome to VR.com! You've come to the right place. A few women who frequent these boards have had heart valve conditions and pregnancies.
I can only speak for myself, and I'm perhaps not the best person -- I haven't had surgery, I'm under monitoring for moderate AI and TI.
I've had three beautiful, healthy children, but my last pregnancy was very, very difficult at the age of 36 and I almost didn't make it. Granted, I'm a little older than you, but pregnancy and aortic valve disease can be life-threatening, especially stenosis. Again, you're younger, and it looks like from your history that your valves have been repaired?
How do you feel? Do you have any symptoms of heart failure? In my research on this subject, if you've ever experienced heart failure (or cardiomyopathy), then you should not get pregnant.
Bottom line, I would ask for at least two, if not three opinions from an OB-GYN who specializes in High Risk cases like yours, i.e., heart valve disease, and also ask for an opinion from another cardiologist. Two heads are better than one!
You can search on "pregnancy" on these boards and read my personal story on the front page of VR.com under KimCaroline.
You have a very, very personal decision to make, and it sounds like you understand the risks. I wish you and your husband the best. Please keep in touch.
God bless,
