Can you tell me about surgery for bicuspid aortic valve disease?

No surgery: Bicuspid aorta is not indication for surgery. However, with age, bicuspid aorta may progress to aortic stenosis (when valve opening is severely limited). Surgery for aortic stenosis is performed only when the aortic valve area is severely or critically reduced (and not before). Progression from bicuspid aorta to aortic stenosis may take years or decades (even sometimes never) to take place.
