Yep I did, and I have posted stats in the past that suggest around 65% of all BAVs result in aneurysm. Some studies suggest higher and some lower so 65% is a pretty accurate middle figure that I consider to be in the ball park.
Over the years from some of the posts here regarding aneurym I would surmise 65% might even be on the low side.
The tissue in the ascending aorta is genetically abnormal in ALL BAV patients according to Grayson whether it results in aneurym or not.
“The exact cause of bicuspid aortic valveis not known, but some medical experts suggest it may be caused by a connective tissue disorder similar to that which causes the heart and blood vessel problems in Marfan syndrome.”
