Fig 2 The leaflet free edge is supported with neochordae of 6-0 expanded polytetrafluoroethylene, sutured to the base of a papillary muscle, but not in the infarcted area. The length is adjusted to neutralize the prolapse.

Fig 3 The tricuspid valve annulus us stabilized using a modified de Vega technique with a 5-0 expanded polytetrafluoroethylene suture. The ends of the suture are passed through the wall of the right atrium and controlled with a tourniquet. The annulus can be adjusted after separation from cardiopulmonary bypass using transesophageal control. (SVC = superior vena cava.)
