Three-dimensional (3D) transthoracic echocardiography has advantages over traditional two-dimensional (2D) echocardiography in visualizing tricuspid valve morphology in Ebstein's anomaly. We describe the application of intra-operative 3D transesophageal echocardiography during a tricuspid valve repair procedure in a patient with Ebstein's anomaly. Intra-operatively three-dimensional transesophageal echocardiographic (3D TEE) data sets revealed morphology and function of the tricuspid valve, right ventricle outflow tract (RVOT) and pulmonary valve before and after repair. Tricuspid valve leaflet morphology and coaptation as visualized with 3D TEE proved to be consistent with intra-operative findings. Analysis of the tricuspid valve, RVOT and pulmonary valve in the multi-planar review (MPR) mode revealed a bicuspid pulmonary valve, which had not been noticed on the preoperative 2D echocardiographic work-up. In this patient with Ebstein's anomaly, 3D TEE provided additional information on morphology and function of tricuspid valve, RVOT and pulmonary valve.
在可视化埃布斯坦畸形中的三尖瓣形态方面，三维（3D）经胸超声心动图比传统二维（2D）超声心动图具有优势。我们描述了术中三维经食管超声心动图在一名埃布斯坦畸形患者三尖瓣修复手术中的应用。术中三维经食管超声心动图（3D TEE）数据集显示了修复前后三尖瓣、右心室流出道（RVOT）和肺动脉瓣的形态和功能。3D TEE显示的三尖瓣叶形态和对合情况与术中发现一致。在多平面回顾（MPR）模式下对三尖瓣、RVOT和肺动脉瓣的分析显示存在一个二叶式肺动脉瓣，这在术前二维超声心动图检查中未被发现。在这名埃布斯坦畸形患者中，3D TEE提供了关于三尖瓣、RVOT和肺动脉瓣形态及功能的额外信息。
