Prenatal diagnosis of hypoplastic left heart syndrome
(HLHS) is associated with improved clinical status
and survival.8 It allows patients to choose to deliver
close to high-volume surgical centers, which decreases
transport and presurgical mortality.9 In 2001, Mahle
et al10 reported that prenatal diagnosis of HLHS is associated
with improved preoperative management and
fewer perioperative neurological events. This study also
demonstrated that operative mortality and hospital stay
in neonates with HLHS were not affected by prenatal
diagnosis.10 However, in 2013, Landis et al11 reported that
prenatal diagnosis of all CHD did not have an impact on
preoperative or predischarge mortality.
