Transesophageal echocardiography（TEE）can help perioperative monitoring and diagnosis for patients undergoing either cardiac or noncardiac surgery perioperatively. Traditional teaching methods for TEE including lecture or real patient training at the bedside were with low efficiency

whereas simulator-based training including 20 TEE standard views

17 segments of the left ventricle

mitral valve zoning and clinical cases learning 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.
