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.
