We report a 19-year-old male patient with familial homozygous hypercholesterolemia with progressive supravalvular and valvular aortic stenosis that ultimately required aortic root enlargement and aortic valve replacement using a mechanical prosthesis, despite aggressive medical therapy. Surgical importance of this rare condition is highlighted.
