  1. Comparison between outcomes seen in patients with antenatally and postnatally detected Hypoplastic Left Heart Syndrome over three life periods: postnatal period, surgical period and long-term.
  2. Denominators for long-term outcomes decreased as cases were lost from analysis due to absence of clinical information.
