Abstract
TEE technology has rapidly evolved with the advancements provided by flexibe endoscopic probes and phased array transducers ultrasound technology.
The additional information available from pulsed wave, continuous wave, and colour Doppler data has led to the rapid acceptance of TEE by the medical, surgical and anesthetic communities. TEE is a diagnostic examination with an ultrasound device passed to the oesophagus to create a clear image of the cardiac muscle and other parts of the heart.
TEE probes are variable, but share several common features, there are adult and pediatric sizes, it can be introduced in Awake patient with local anesthetic and sedation or in anesthetized patients.
The tips of all TEE transducers can be flexed to some degree both antroposteriorly and laterally to accommodate the different angles that may be required to visualize various parts of the heart and great vessels.
A refrence is usually displayed on the screen indicating longitudinal (L) or transverse (T) plane.
In transverse plane (0) the probe is moved up and down in the oesophagus in order to obtain the standard imaging planes. While imaging in the longitudinal plane, the operator rotates the probe clockwise and counterclockwise along its long axis.
