Transthoracic 2-dimensional (D) echocardiography (echo) is often used to assess tricuspid regurgitation (TR) after implantation of permanent pacemakers. However, its ability to define the precise anatomical relationship between the tricuspid valve and the pacemaker lead is quite limited. This report presents a 58-year-old male with aggravation of TR after pacemaker implantation for heart block. Three-D echo precisely depicted the entrapment of the lead shaft in the fused and fibrotic septal and posterior tricuspid leaflets. The patient underwent tricuspid valve annuloplasty and the symptoms of right heart failure improved soon after the operation.
经胸二维（2D）超声心动图（超声）常用于评估永久性起搏器植入术后的三尖瓣反流（TR）。然而，其明确三尖瓣与起搏器导线之间精确解剖关系的能力相当有限。本报告介绍了一名58岁男性，因心脏传导阻滞植入起搏器后TR加重。三维超声精确显示了导线轴陷入融合和纤维化的间隔及三尖瓣后叶。患者接受了三尖瓣环成形术，术后右心衰竭症状很快得到改善。
