title: Accelerated allograft degeneration after aortic valve endocarditis.
abstract: Early calcification of aortic allografts is usually seen in children less than 3 years of age. We describe a case of a 22-year-old intravenous drug user who developed calcific aortic valve stenosis less than 3 years after an allograft root replacement for endocarditis.
