Sequential images depicting polytetrafluoroethylene (PTFE) tricuspid valve fabrication process. A and B, Trimming of PTFE conduit and membrane. C, The PTFE conduit is turned inside out. D, Three straight lines are marked. E and F, The PTFE conduit is wrapped with the trimmed PTFE membrane sheet. G, The PTFE membrane is fixed to the conduit at the points indicated by the 3 lines, with a double layer of in-and-out vertical continuous sutures applying a fine straight vascular clamp. H, Subcommissural triangles are made using CV-6 PTFE over-and-over suture. I, The conduit is turned inside out again. J, The commissural sutures are deployed at 3 fixed sites. K, One size-up PTFE conduit wraps the PTFE valve. L, A 0.4-mm-thick PTFE patch is anastomosed to the distal end of the PTFE valve.
