Pacemaker lead-related tricuspid stenosis successfully treated with percutaneous balloon valvuloplasty guided by 3D echocardiography

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 steno- sis without associated valvular regurgitation, mostly related to pacemaker leads. Percutaneous tricuspid valvuloplasty may be a therapeutic alternative to surgery in cases of pure tricus- pid 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. © 2014 Sociedade Portuguesa de Cardiologia.
