Abstract Patients with single ventricle (SV) heart defects have two primary surgical options for superior cavopulmonary connection (SCPC): bidirectional Glenn (BDG) and hemi-Fontan (HF). Outcomes based on type of SCPC have not been assessed in a multi-center cohort. This retrospective cohort study uses the Single Ventricle Reconstruction (SVR) Trial public use dataset. Infants who survived to SCPC were evaluated through 1 year of age, based on type of SCPC. The primary outcome was transplant-free survival at 1 year. The cohort included 343 patients undergoing SCPC across 15 centers in North America; 250 (73%) underwent the BDG. There was no difference between the groups in pre-SCPC clinical characteristics. Cardiopulmonary bypass times were longer [99 min (IQR 76, 126) vs 81 min (IQR 59, 116), p
