“Transesophageal echocardiography (TEE) is a commonly performed procedure, either in an
intra-operative setting of a cardiac surgical procedure or a nonoperative setting, such as to evaluate for an intracardiac thrombi.”

“Majority of the esophageal perforations occur in cases with a perceived low risk or smooth TEE exam and thus, screening for high risk factors may not eliminate the occurrence of a perforation. A delayed detection of perforation occurs when it is a thoracic esophageal perforation, performed intra-operatively and when there are no known preoperative risk factors. Shock during the detection of the perforation is associated with mortality. Majority of the perforations can be repaired primarily.””Majority of the esophageal perforations occur in cases with a perceived low risk or smooth TEE exam and thus, screening for high risk factors may not eliminate the occurrence of a perforation.
