Current outcomes of the Glenn bidirectional cavopulmonary connection for single ventricle palliation†

OBJECTIVES: The Glenn bidirectional cavopulmonary connection (BCPC) is an established procedure in multistage palliation of various single ventricle (SV) anomalies. We aimed to report the current outcomes following BCPC and to examine risk factors affecting survival and progression to the next palliation stage. METHODS: Two hundred and twenty-seven consecutive children with variable SV pathologies underwent BCPC from 2002 to 2007. Competing risk analyses were performed to model events after BCPC (death and transition to Fontan) and subsequently after Fontan (death and cardiac reoperation) and to examine the associated risk factors for poor outcomes. RESULTS: There were 139 males (61%) with a median age of 7.6 months [interquartile range (IQR) 6.0–10.8] and median weight of 6.2 k
