Hi @oligarcia, the outcomes for surgery are better before you get symptoms of congestive heart failure (shortness of breath), and it's also better to repair a valve vs replace it.
Your husband's advice is good - it's best to consult with a cardiologist. I agree with @mikaylar.
You said your condition wakes you up at night. Is that because you're short of breath or is it anxiety and worry?
I had a mitral valve repair five years ago before I had any symptoms and I'm glad I had it done then. Since then I've developed other disorders which would have complicated things.
