Infectious process with large periprosthetic abscess involving biological prosthesis. (a) Abscess formation of conventional stented bioprosthesis. (b) The prosthesis is removed with vegetations. (c) Biological living tissue explanted and cryopreserved (homograft) is used for aortic root reconstruction and for repair of mitro-aortic curtain. (d) The infected prosthesis is removed with aggressive debridement of all infected and necrotic tissue. The coronary ostia are prepared for the reconstruction of aortic root.
