Transøsofageal

Transøsofageal is a medical descriptor meaning through the esophagus. In contemporary usage, it is most often encountered in relation to transøsofageal (transesophageal) techniques, procedures, or imaging. The term reflects the anatomical route via the esophagus to access the thoracic cavity or to place imaging devices in proximity to the heart and mediastinal structures. In Norwegian and other Scandinavian languages, ø is used in place of the sequence “oe” or “o” in “oesophageal.”

The most common application is transøsofageal echocardiography (TOE or TEE), where a compact ultrasound probe is inserted into the esophagus. This provides high-resolution images of cardiac chambers, valves, and adjacent anatomy, often during surgery or in patients where transthoracic imaging is insufficient. Other transøsofageal uses include guiding interventional procedures or delivering therapies via an esophageal route when direct access to cardiac or mediastinal structures is necessary.

Risks and considerations: The procedure requires sedation or anesthesia and monitoring. Possible complications include esophageal irritation or injury, perforation, bleeding, aspiration, and airway compromise. Contraindications include significant esophageal pathology (such as strictures or varices), active bleeding, severe coagulopathy, or swallowing disorders. Benefits include improved image quality and the ability to perform real-time guidance during procedures, especially in cardiology and perioperative settings.
