Preoperative Nakata index before total cavopulmonary connection in the primary group (circles), before a bidirectional Glenn shunt in the staged group (squares), and before total cavopulmonary connection in the staged group (diamonds). The Nakata index decreased significantly after the bidirectional Glenn shunt in the staged group, and its mean value was also significantly smaller than that observed in the primary group.
