Objectives/Hypothesis: Infants who undergo congenital heart surgery are at risk of developing vocal fold motion impairment (VFMI) and swallowing difficulties. This study aims to describe the dysphagia in this population and explore the associations between surgical complexity and vocal fold mobility with dysphagia and airway protection.Study Design: Retrospective chart review. Methods: This is a retrospective chart review of infants (age <12 months) who underwent congenital heart surgery between 7/2008 and 1/2018 and received a subsequent videofluoroscopic swallow study (VFSS). Demographic information, Society of Thoracic Surgeons-European Association for Cardio-Thoracic Surgery (STAT) category of each surgery, vocal fold mobility status, and VFSS findings were collected and analyzed.Results: Three hundred and seventy-four patients were included in the study. Fifty-four percent of patients were male, 24% were premature, and the average age at the time of VFSS was 59 days. Sixty percent of patients had oral dysphagia and 64% of patients had pharyngeal dysphagia. Fifty-one percent of patients had laryngeal penetration and 45% had tracheal aspiration. Seventy-three percent of these aspirations were silent. There was no association between surgical complexity, as defined by the STAT category, and dysphagia or airway protection findings. Patients with VFMI after surgery were more likely to have silent aspiration (odds ratio = 1.94, P < .01), even when adjusting for other risk factors.Conclusion: Infants who undergo congenital heart surgery are at high risk for VFMI and aspiration across all five STAT categories. This study demonstrates the high prevalence of silent aspiration in this population and the need for thorough postoperative swallow evaluation.

Objectives: Cerebral palsy (CP) in infants can affect global motor function and lead to swallowing difficulties. This study aims to characterize oral and pharyngeal swallowing dynamics in infancy of patients later diagnosed with CP and to determine if swallow study performance in early infancy is associated with later CP severity and characteristics. Methods: This is a retrospective chart review of infants who underwent videofluoroscopic swallow studies (VFSS) between 6/2008 and 10/2018 at a tertiary children’s hospital, and were later diagnosed with CP. Demographic data, CP characteristics and metrics, and VFSS findings were collected and analyzed. Results: There were 66 patients included in this study. The average age at the time of VFSS was 4 months (range: 0.3-12 months), 42% of patients were female, and 50% of patients were born premature. In our sample, 86% of patients presented with oral dysphagia, and 76% with pharyngeal dysphagia. Laryngeal penetration in isolation was seen in 39% of patients, and tracheal aspiration was seen in 38% of patients. Of these tracheal aspiration events, 64% were silent. At the time of VFSS, 58% of patients had a nasogastric tube, 12% had a gastrostomy tube, and 3% had a prior hospitalization for pneumonia. Rates of penetration and aspiration in early infancy did not consistently correlate with prematurity, type of CP (spastic, non-spastic, or mixed), degree of paralysis (quadriplegic, hemiplegic, or diplegic), or severity of Gross Motor Function Classification System (GMFCS) score. Conclusion: While there was not a consistent correlation of swallowing dynamics in infancy with later gross motor categorizations of CP, the results of this retrospective review highlight the essential role of early clinical and videofluoroscopic swallowing evaluations to identify oral and pharyngeal swallowing dysfunction in this patient population.
