A 54-year-old male was found to have neuroendocrine carcinoma with hepatic metastasis. Two-dimensional (2D) transthoracic echocardiography (TTE) demonstrated dilated right ventricle and right atrium, and severe tricuspid and pulmonary regurgitation. Three-dimensional (3D) TTE en-face views showed thickened, retracted, and fixed tricuspid valve and pulmonic valve which remained widely open throughout the cardiac cycle. 3D TTE, particularly en-face views, demonstrates incremental value over 2D TTE by providing precise valvular anatomic details comparable to surgical findings. 3D TTE also offers a unique opportunity to assess all four valves simultaneously with en-face views to delineate their relationships with surrounding structures.
一名 54 岁男性被发现患有伴肝脏转移的神经内分泌癌。二维（2D）经胸超声心动图（TTE）显示右心室和右心房扩张，三尖瓣和肺动脉瓣重度反流。三维（3D）TTE 直面观显示三尖瓣和肺动脉瓣增厚、回缩和固定，在整个心动周期中保持广泛开放。3D TTE，特别是直面观，通过提供与手术发现相媲美的精确瓣膜解剖细节，比 2D TTE 具有更多的附加价值。3D TTE 还提供了一个独特的机会，可以通过直面观同时评估四个瓣膜，以描绘它们与周围结构的关系。
