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 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. Resumo: A causa mais comum da estenose tricúspide é reumática, e na maioria dos casos está associada com insuficiência valvular. Curiosamente, tem havido relatos de estenose tricúspide sem insuficiência associada, sendo a maioria associados com electrocateteres de pacemaker. A plastia da valva tricúspide pode ser uma alternativa em casos de estenose valvular tricúspide pura, sem outras valvulopatias concomitantes. Relatamos o caso de uma mulher de 52 anos com estenose tricúspide associada a electrocateter de pacemaker tratada com sucesso com valvuloplastia percutânea guiada por ecocardiografia 3D.
