Surgical Treatment of Active Native Aortic Valve Endocarditis With Allografts and Mechanical Prostheses

However, this is in combination with extensive excision of destructive tissue in a specific patient subset. Allograft reoperation rates increase with time. The importance of the mechanical prosthesis in NVE might be established in the coming years.
