[Aortic root replacement using an allograft for active infective endocarditis with periannular abscess: single center experience].

Objectives: Results of aortic root replacement using an allograft for active infective endocarditis in the aortic position and periannular abscess were studied.

Methods: Aortic root replacement using a cryopreserved aortic allograft was performed 13 times in 12 patients (9 men, 3 women, mean age 52.8 years) at Saitama Medical School.

Short-term result of aortic valve replacement with cryopreserved homograft valve in the University of Tokyo Tissue Bank.

The short-term results after aortic root replacement with 11 cryopreserved aortic homografts was examined. Since 1998, the University of Tokyo Tissue Bank has supplied 11 aortic homograft valves. Nine of the recipients were male, and the average age was 51.
