I'm a 59 yr old male with a BAV. I had my last echo in Oct. of 2013. My doctor said my result were ok, mild stenosis. My question is that I've had several bouts of shortness of breath while doing strenuous activity outside in the cold. Had some light headedness when standing. Would it be advisable to see a cardiologist with expertise in congenital heart disease? I have never had a consult from any cardiologist.
