title: Repair of double-chambered right ventricle: surgical results and long-term follow-up.
abstract: BACKGROUND
  We reviewed the outcomes of double-chambered right ventricle repair.
  
  
  METHODS
  Between 1969 and 1998, 40 patients underwent surgical repair of a double-chamber right ventricle. The patients ranged in age from 3 months to 52 years (mean, 12.8 +/- 11.6 years). Right ventricular outflow tract pressure gradients were from 20 to 170 mm Hg (mean, 65.0 +/- 38.5 mm Hg) An associated ventricular septal defect was present in 27 patients (67.5%). Four patients were older than 30 years of age.
  
  
  RESULTS
  There were no hospital or late deaths. Mean postsurgical follow-up was 16.5 +/- 8.9 years (range, 2.5 to 31 years). No patient required further surgery to relieve obstruction of right ventricular outflow tract.
  
  
  CONCLUSIONS
  Surgical repair of a double-chambered right ventricle yields excellent hemodynamic and functional results over both the short and long term.
