Abstract Background: Deficits in swallowing physiology are a leading morbidity for infants with functional
single ventricles and systemic outflow tract obstruction following stage 1 palliation. Despite the
high prevalence of this condition, the underlying deficits that cause this post-operative impairment
remain poorly understood.
Objective: Identify the physiologic correlates of dysphagia in infants with functional single ventricles and systemic outflow tract obstruction following stage 1 palliative surgery.
Methods: Postoperative fiberoptic laryngoscopies and videofluoroscopic swallow studies (VFSS)
were conducted sequentially on infants with functional single ventricles following stage 1 palliative
surgery. Infants were dichotomized as having normal or impaired laryngeal function… More >
