title: Fontan completion after Norwood with bidirectional Glenn shunt: their haemodynamics and pulmonary artery configuration.
abstract: OBJECTIVE
  We ranked the haemodynamics and pulmonary artery (PA) configurations of Norwood with bidirectional Glenn shunt (NW-G) patients among the other staged Fontan completion (conventional) patients in this study.
  
  
  METHODS
  Between August 2001 and April 2010, 91 consecutive patients completed staged Fontan operations. Among them, NW-G was performed in 11.
  
  
  RESULTS
  There was no operative or late death except in one case which resulted from a reoperation after Fontan completion. Although the age at bidirectional Glenn (BDG) and Fontan completion was younger in NW-G (4.2 vs. 10.9 months, P < 0.01, and 2.3 vs. 3.3 years, P < 0.01), the interval between BDG and Fontan completion was not significantly different in these groups (23.6 vs. 28.0 months, P = 0.71). On Fontan completion, the extracardiac conduit size was significantly different (16.4 vs. 17.7 mm, P < 0.01). However, the pulmonary artery size (PA index) and the PA pressure were not significantly different (165.4 vs. 205.1 mm(2)/m(2), P = 0.23, and 13.4 vs. 11.0 mmHg, P = 0.08). Particularly in hypoplastic left heart syndrome patients, the PA index was not significantly different between these groups (165.4 vs. 174.9 mm(2)/m(2), P = 0.59).
  
  
  CONCLUSIONS
  The NW-G patients could have a subsequent Fontan completion with good results. There was no significant difference with respect to Fontan completion.
