Picture shows a tricuspid indigenous Goretex steel ring ring being implanted. Since the ring is complete the stitches at the base are placed on the base of the septal leaflet rather than on the annulus at the region of the conduction system (between anteroseptal commissure and the coronary sinus orifice. Note that the ring sizers and ring are used in the opposite manner compared to regular mitral sizing and implantation.
