Lead Author Year Patients Outcomes
Lundstrom[83] 1990 111 patients from Hospital for Sick Children and National Heart Hospital of whom51 underwent surgery
  • Operative mortality: 11/51 (22%)
  • Dilated systemic ventricle is a risk factor for a poor outcome
  • Termignon[79] 1996 52 patients from Laennec Hospital, Paris
  • Operative mortality: 15%
  • Survival: 83% at 1 year, 55% at 10 years (for patients with associated VSD/LVOTO) while those with only associated VSD had 71% survival at 10 years
  • Van Son [80] 1995 40 patients from Mayo Clinic
  • Operative mortality 10%
  • Survival: 78% at 5 years, 61% at 10 years
  • RVEF  > 44% favored survival
  • Yeh[81] 1999 127 patients underwent surgery at Hospital for Sick Children,median age at operation was8 years
  • Operative mortality 6%
  • Survival: 48% at 20 years
  • Hraska[82] 2005 123 patients underwent surgery at Children’s Hospital Boston, median age at operation was 7.9 years
  • Survival: 84% at 1 year, 75% at 5 years; 68% at 10 years, and 61% at 15 years
  • Freedom from RV dysfunction (2V repair) 43% at 15 years
  • Ebstein malformation of the tricuspid valve is a risk factor for RV dysfunction
  • VSD – Ventricular septal defect; LVOTO – Left Ventricular Outflow Tract Obstruction; RVEF – Right Ventricular Ejection Fraction; V – Ventricle; TVR – Tricuspid Valve Replacement; RV – Right Ventricle
