Transesophageal echocardiography (TEE) can help anesthesiologists to monitor and diagnose for patients undergoing either cardiac or noncardiac surgery perioperatively

so it is essential and important to master TEE skills for anesthesiologists . Training methods for TEE including lecture or real patient training at the bedside with low efficiency

whereas simulator-based training which acting as a new teaching tool was proved to save the time

provide more opportunities

reduce patient-related complications

and it has been gradually used in clinical teaching with satisfied feedback .The simulator teaching modules included 20 TEE standard views

17 segments of the left ventricle

mitral valve zoning

and clinical cases learning etc. Simulator can help to realize the integration of theory and practice in TEE training

but it still has the disadvantages of not be able to measure spectrum and other indicators

dynamic monitoring as well as high price cost. In summary

simulator can help novice trainees to quickly acquire TEE basic knowledge

combine with regular TEE training programs and develop new modules may be more helpful for anesthesiologists to learn TEE.
