title: Surgical management of severe truncal insufficiency: experience with truncal valve remodeling techniques.
abstract: BACKGROUND
  Truncal valve insufficiency has been a significant short- and long-term risk factor for repair of truncus arteriosus. Recent reports have documented the virtues of truncal valve repair. The purpose of this report is to review our experience with truncal valve repair and illustrate our techniques.
  
  
  METHODS
  Between 1995 and 2000, 8 patients had interventions for severe truncal valve insufficiency at primary repair (3 patients) or in conjunction with conduit replacement (5 patients). One neonate had truncal valve replacement at initial repair early in the experience. The other 7 patients had truncal valve repair, 3 by valvar suture techniques. The remaining 4 patients had leaflet excision and annular remodeling in 3 (coronary reimplantation was required in 2) and commissure resuspension in 1 patient.
  
  
  RESULTS
  Trivial to mild truncal valve insufficiency is present in the patients who had leaflet excision and annular remodeling (n = 3) and commissure resuspension (n = 1). Of the 3 patients who had valvar suture truncal valve repair, there was one death and 2 patients required acute valve replacement. The 7 survivors are doing well 1 month to 6 years postoperatively.
  
  
  CONCLUSIONS
  Truncal valve repair by valvar suture techniques has not been successful in our practice. Truncal valve remodeling by leaflet excision and reduction annuloplasty is an effective method for truncal valve repair. When leaflet excision of a coronary sinus of Valsalva is required, coronary artery translocation can be accomplished.
