Dysphagia is common in infants with congenital heart disease (CHD). However, there is minimal published data regarding its management outside of the perioperative period. The objective of this study is to describe the role of Fiberoptic Endoscopic Evaluation of Swallowing (FEES) in the diagnosis and management of dysphagia in infants with CHD. Infants with CHD who underwent FEES exam for evaluation of swallowing dysfunction between February 2015 and February 2021 at a university-based, tertiary care urban pediatric hospital were studied. Demographic data, presenting symptoms, medical history, and dysphagia history were examined. The validated Dysphagia Outcome and Severity Scale (DOSS) was used to standardize and compare dysphagia severity. 62 FEES exams were performed on 48 patients. All 48 patients were diagnosed with dysphagia and had a mean dysphagia severity score (DOSS) of 2.68. Patients with wet laryngeal congestion on presentation had worse mean DOSS score and were more likely to demonstrate aspiration on FEES exam (p < 0.01). There was no significant difference in mean DOSS or presence of aspiration when comparing infants who had cardiothoracic surgery, vocal cord paralysis, or lower respiratory tract illness with those who had not (p > 0.05). A FEES exam is an effective and well-tolerated procedure for evaluating swallowing dysfunction in pediatric patients with CHD and its use reduces radiation exposure for this vulnerable population. Wet laryngeal congestion was found to be predictive of more severe dysphagia and aspiration. There is no significant association between severity of dysphagia or aspiration on FEES exam and history of cardiac surgery, vocal cord paralysis, or lower respiratory tract illness. •FEES is a safe procedure for evaluating dysphagia in pediatric patients with CHD.•Wet laryngeal congestion was predictive of more severe dysphagia and aspiration.•No significant association between cardiac surgery history and dysphagia severity.•No significant association between aspiration and lower respiratory tract illness.
