BackgroundEbstein's anomaly (EA) is a rare and complex congenital heart anomaly, and the effect of surgical treatment is not ideal. This study aims to introduce our experience in management strategies, surgical techniques, and operative indications for patients with Ebstein's anomaly.MethodsA retrospective study of 258 operations was performed in 253 patients by the same cardiac surgeon in The First Hospital of Tsinghua University between March 2004 and January 2020. 32 patients had previously received cardiac surgery in other hospitals. The clinical data including diagnosis, operative indications, techniques, pathological changes, and survival rates were collected and analyzed.ResultsAnatomical correction was performed in 203 (78.7%) operations, 1½ ventricle repair in 38 (14.7%) operations, tricuspid valve repair only in four operations (1.6%), tricuspid valve replacement in ten (3.9%), total cavopulmonary connection (TCPC) in two (0.8%), and Glenn operation in one operation (0.4%). Reoperation was performed in five patients (2.0%) during hospitalization. Among them, tricuspid valve replacement was performed in one patient, 1½ ventricle repair in two patients, and tricuspid valve annulus reinforcement in two patients. Five patients died with an early mortality rate of 2.0%. Complete atrioventricular conduction block was complicated in one patient (0.4%). A total of 244 patients was followed up (four in the 253 patients lost) with a duration of 3.0-168.0 (87.6 ± 38.4) months. Cardiac function of 244 patients improved significantly with mean New York Heart Association (NYHA) functional class recovery from 3.5 to 1.1. The mean grade of tricuspid valve regurgitation improved from 3.6 to 1.5. Three late deaths (1.2%) occurred. The survival rates at five and ten years after surgery were 98.6% and 98.2%, respectively. Reoperation was performed in five patients (2.0%) during the follow-up period.ConclusionBased on our management strategies and operative principles and techniques, anatomical correction of EA is capable of achieving excellent long-term results, and low rates of TCPC, 1½ ventricle repair and valvular replacement.Copyright © 2024 The Chinese Medical Association, produced by Wolters Kluwer, Inc. under the CC-BY-NC-ND license.
