Fig 1 The bioprosthesis–Dacron tube conduit was completed with the bovine pericardial strip covering all Dacron surfaces, with the smooth surface out. The Annals of Thoracic Surgery 2003 75, 1987-1989DOI: (10.1016/S0003-4975(02)04658-1)
Fig 2 Drawing of the conduit-on-valve mitral re-replacement. All degenerated leaflet tissue is removed (arrow), and the bioprosthesis–Dacron tube composite graft is apposed to the inflow aspect of the previous bioprosthetic stent.

Fig 3 Intraoperative appearance of the completed bioprosthesis–Dacron tube conduit mitral re-replacement. The composite graft sits on the atrial aspect of the previous bioprosthetic stent. The Annals of Thoracic Surgery 2003 75, 1987-1989DOI: (10.1016/S0003-4975(02)04658-1)
