For parents of children with CHD's only (you won't be interested otherwise). I found this November 7th publication on guidelines for management of adult patients with CHD's. I know some of the issues have been discussed at our group before. It is a PDF file you would have to download.
Cardiology/American Heart Association Task Force on Practice Guidelines:
Executive Summary: A Report of the American College of ACC/AHA
2008 Guidelines for the Management of Adults With Congenital Heart Disease.
It outlines management issues for CHDs including patients with Shones and many issues associated with LVOT obstruction, criteria for valve replacement and issues with bicuspid aortic valves.
