"A standard transoesophageal echocardiography (TOE, or TEE in US English) is a type of echocardiography using an endoscopic transducer, which is advanced into the thoracic oesophagus, offering generally superior visualisation of the great vessels and posterior cardiac structures than the standard transthoracic approach (TTE). Transoesophageal echocardiography is most frequently used in specialities such as anaesthesia, cardiology, and critical care, for evaluation of cardiac and aortic structures."

"Typically performed in an intubated, sedated patient (although examination with the use of topical anaesthesia and low-dose analgesia is possible, with or without the use of opioid adjuncts). A bite block is placed, the jaw mobilised anterocaudally, and the probe is inserted into the oropharynx, guided by either fingers or a laryngoscope 8."

"A comprehensive exam utilises four different positions in the alimentary tract; the upper oesophagus, midoesophagus, transgastric, and deep transgastric levels 1. The midoesophageal level is usually found between 30 and 35 cm from the oropharynx where one may visualise the left atrium in the near field, a common reference point; to find the upper oesophageal position, one retracts until the aortic arch is visualised, whereas advancing to the rugae of the stomach with subsequent anteflexion will bring one to the transgastric position."
