transesophageal echocardiography
Advanced cardiac imaging technique using an esophageal probe, providing superior visualization of cardiac structures in critically ill patients.
Full Definition
Transesophageal echocardiography (TEE) is an advanced cardiac imaging modality that uses an ultrasound transducer mounted on a flexible endoscope inserted into the esophagus. This approach provides superior image quality compared to transthoracic echocardiography, particularly in mechanically ventilated patients or those with chest wall abnormalities. TEE is invaluable for assessing cardiac function, detecting valvular pathology, evaluating for sources of embolism, and guiding cardiac interventions in the operating room and ICU. The procedure requires specialized training and patient sedation.
Usage
Usage note: Commonly abbreviated as TEE; specify intraoperative vs ICU setting when relevant.
