Diagnosis of Extrinsic Upper Esophageal Compression Utilizing Video Laryngoscopy in an Infant Following Failed Transesophageal Echocardiogram Probe Placement

Anesthesiologists are frequently responsible for placement of transesophageal echocardiography probes prior to cardiac surgery in children. A number of potential complications are possible, including placement failure. This report documents one such failed attempt at probe placement in a 3-month-old patient with a history of ventricular septal defect, and the utilization of video laryngoscopy by the anesthesiologist to diagnose a previously unknown extrinsic esophageal compression likely caused by an aberrant right subclavian artery. This case highlights the multiple vascular anomalies that may act as a source of esophageal obstruction in children undergoing transesophageal echocardiography for cardiac surgery.
