child with calcified valve

Hi, My husband is 25.  As a child he was diagnosed as being bicuspid with mild aortic stenosis then lost to follow-up. Recently due to shortness of breath he has begun process of following up on his heart in which time I have found all his records which reported that at the young age of twelve he surprisingly already had heavy calcification.  We have had two follow-up echo's, at two differnet places in the last month, both of which found him to be tricuspid, but again with calcification of his aortic valve.  It will be a while before he makes it back to his cardiologist for an intrepretation but I am trying to figure out what would cause the calcification if he is tricuspid, especially as a child.  He has never had radiation treatment, does not have lupus, and no rheumatic fever.  

Thanks

At his age calcification in the aortic valve would have to be most commonly secondary to either a bicuspid aortic valve or undiagnosed rheumatic heart disease. If there is any question about it he can undergo a transesophageal echocardiogram to better ***** the nature of the calcification and whether the valve is tricuspid or not. More importantly however is whether or not he has any aortic stenosis and or regurgitation, and that should be readily apparent from his surface echocardiogram.

Thank you, he does have stenosis and the beginnings of an aneurysm and just underwent a 64 slice CT scan to better delineate this.  I was really wanting to know if this was something that could be passed down to our daughter or not and something we need to pursue further with her and wondering what other causes there could be for the build-up.  

Thank you again.
