Abstract：Objective: To explore the application value and the guidance for surgical operation of transthoracic echocardiography(TTE) and multiplane transesophageal echocardiography(MTEE) in the diagnosis of Ebstein’s anomaly. Methods: Preoperative TTE features in 13 cases of Ebstein’s anomaly and intraoperative MTEE features in 5 of them were analyzed retrospectively, comparison to the operation results was carried out． Results: Among the 13 cases, 1 case was diagnosed as Ebstein’s anomaly with solitary displacement of septal leaflet, 12 cases with displacement of septal and posterior leaflets by TTE. Among the 5 cases, 2 cases were diagnosed as severe displacement of the leaflets with functional right ventricle hypoplasia and thinning of the wall, 3 cases with severe abnormalities of the leaflets by MTEE. Among the 13 cases with different degree of abnormalities, 6 cases received valvuloplasty, 5 cases received valvular replacement procedure, 2 cases received bidirectional Glenn shunt procedure. Conclusions: TTE can diagnose Ebstein’s anomaly, MTEE can evaluate the function of tricuspid leaflets and right ventricle more accurate, if the two examination methods were combined together, they can help surgeon to choose the better operation methods for treating various degree of anomalies and improve the success rate.
