title: [Surgical treatment of flail leaflet of tricuspid valve].
abstract: OBJECTIVE
  To explore the approach and the result in tricuspid valve insufficiency treatment by a cusp remodeling technique.
  
  
  METHODS
  Nine patients with severe tricuspid regurgitation, congenital lack of chordae in 6 cases and traumatic rupture of chordae in 3 cases, underwent surgical repair between April 1997 and March 2006. There were six male and three female. Their ages ranged from 8 years to 57 years. One or two segments of flail leaflets were presented in these patients. Valve repair was performed by suture of the free edge of the affected cusp segment, plication of the segment of annulus devoid of leaflet, and fixation of the neo-annulus with a flexible annuloplasty ring.
  
  
  RESULTS
  All patients survived and recovered after the operation. Echocardiography showed good coaptation with no regurgitation of the tricuspid valve in six patients and a mild residual tricuspid regurgitation in three. A remarkable decrease in the diameter of the right ventricle (anterior to posterior) was observed: from mean (43.6 +/- 4.2) mm (range 29 mm to 64 mm) preoperatively reducing to mean (24.0 +/- 1.8) mm (range 16 mm to 32 mm) postoperatively. All patients are doing well in 1 month to 109 months follow up.
  
  
  CONCLUSIONS
  The procedure provided a simple and valuable option for repair of flail leaflet of tricuspid valve caused by congenital lack of chordae or traumatic rupture of chordae.
