In recent years,as the continuous innovation and clinical application of interventional treatment of structural heart disease,echocardiography,especially intraoperative transesophageal echocardiography guidance and monitoring,are of great value.Therefore,a new sub-specialty with higher requirements for knowledge frame-work and clinical skills emerged from echocardiography,which is interventional echocardiography.For different structural heart disease,different surgical procedures,different interventional treatment equipment and clinical ap-plication scenarios,interventional echocardiography has higher technical and job competency requirements for practitioners.In this review,we will briefly describe the origin and development of interventional echocardio-graphy,introduce the training and assessment content and basic skill requirements,and look forward to the fu-ture.
