Rapid advances have been made in stage 1 Norwood palliation for hypoplastic left heart syndrome, with hospital survival now approaching 93%.1 Tricuspid valve regurgitation (TR) and right ventricular dysfunction, however, continue to carry very high early and medium-term mortalities.2 TR significant enough to warrant intervention is observed in 25% of children with hypoplastic left heart syndrome.3 Significant TR is associated with a worse survival at 1 year,3 and successful repair can result in equivalent survival at 5 years.
