What is one contraindication for performing a transesophageal echocardiogram (TEE)?

Transesophageal echocardiography (TEE) is a specialized echocardiographic procedure that provides detailed images of the heart and surrounding structures by inserting a probe into the esophagus. One critical contraindication for performing a TEE is the presence of esophageal strictures.

Esophageal strictures are narrowings of the esophagus that can make the passage of the TEE probe difficult or impossible. Attempting to insert a probe through a narrowed segment could lead to trauma to the esophagus, perforation, or other severe complications. Medical professionals must assess the condition of the esophagus before proceeding with TEE to ensure patient safety.

In contrast, other conditions listed—such as obesity, kidney disease, and diabetes—can influence patient management and anesthesia but do not present the same direct physical risk to the procedure itself as esophageal strictures do. Therefore, esophageal strictures are recognized as a significant contraindication when considering whether to perform a TEE.
