TEE
Pronunciation: TEE (pronounced as the letter)
Also written as: TEE — transesophageal echocardiography
Transesophageal echocardiography, an imaging technique using an ultrasound probe inserted through the esophagus for detailed cardiac visualization.
Full Definition
TEE (transesophageal echocardiography) is a specialized echocardiographic technique that provides superior image quality compared to transthoracic echocardiography by positioning the ultrasound transducer in the esophagus, directly behind the heart. This semi-invasive procedure requires conscious sedation and offers excellent visualization of posterior cardiac structures, valvular apparatus, and potential sources of embolism such as left atrial appendage thrombi. TEE is particularly valuable for guiding cardiac interventions, assessing prosthetic valves, and detecting endocarditis vegetations. The procedure carries minimal risk but requires appropriate patient preparation and monitoring.
Usage
Usage note: Always capitalize. Distinguish from TTE (transthoracic echocardiography). Note 'esophageal' spelling in US usage.
