The most common etiology of tricuspid stenosis is rheumatic, and in most cases it is associated with valvular regurgitation. Interestingly, there have been reports of tricuspid stenosis without associated valvular regurgitation, mostly related to pacemaker leads. Percutaneous tricuspid valvuloplasty may be a therapeutic alternative to surgery in cases of pure tricuspid stenosis without other concomitant valvulopathies. We report the case of a 52-year-old woman with pacemaker lead-related tricuspid stenosis successfully treated with percutaneous valvuloplasty guided by 3D echocardiography.
三尖瓣狭窄最常见的病因是风湿性，在大多数情况下它与瓣膜反流相关。有趣的是，有报道称存在无瓣膜反流的三尖瓣狭窄，大多与起搏器导线有关。对于没有其他合并瓣膜病变的单纯三尖瓣狭窄病例，经皮三尖瓣球囊成形术可能是手术治疗的一种替代方法。我们报告了一例52岁女性因起搏器导线相关的三尖瓣狭窄，在三维超声心动图引导下经皮球囊成形术成功治疗的病例。
