Transesophageal echocardiogram (TEE) can promote the quality of cardiac surgery and reduce peri-operative complications, and thus has been gradually accepted by cardiac surgeons. Through an esophageal probe, TEE can clearly visualize the internal structure of the heart without interrupting surgical procedure. As a newly developed technology which breaks the limitations tied to the traditional two-dimensional TEE, the realtime threedimensional transesophageal echocardiogram (RT3D-TEE) has the advantages of showing threedimensional structure of the heart and providing full range of anatomical information of the heart. Furthermore, it can precisely analyze the anatomical structure of the abnormal heart valves and provide assessment of the change of heart volume. Relying on its unique imaging property, it can largely facilitate preoperative decision-making and provide realtime intraoperative guidance as well as accurate postoperative evaluation. It has now been successfully applied in various types of cardiac surgical procedures including valve repair surgery, congenital heart defect intervention, cardiac mass removal as well as heart function evaluation. In this article, we will review the applications of RT3D-TEE in cardiac surgery, and try to form a basis for its further clinical application.
