Pacemaker lead related tricuspid stenosis: a report of two cases.
نویسندگان
چکیده
Only four cases of tricuspid stenosis related to endocardial pacemaker leads have been reported. Two further cases associated with perforation of a tricuspid valve leaflet by a pacemaker lead are presented: a 46 year old woman and a 60 year old man. It is possible that tricuspid valve disease related to endocardial pacemaker and non-thoracotomy defibrillator leads is underrecognized. Diagnosis requires clinical suspicion and the use of Doppler echocardiography. Recent evidence of fibrosis affecting the tricuspid valve in hearts from patients who have had non-thoracotomy defibrillator implants suggests that this problem could be more common in the future.

[Pacemaker lead-induced tricuspid stenosis: a report of two cases].
Tricuspid stenosis (TS) is an uncommon complication of transvenous ventricular pacemaker implantation, with few cases reported in the literature. The mechanisms described are obstruction of right ventricular inflow by tricuspid vegetations (endocarditis), multiple pacemaker leads and tricuspid valve (TV) fibrosis secondary to perforation or laceration of the TV leaflets, or adherence between re...
متن کاملPacemaker 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 co...
متن کامل[Tricuspid stenosis after pacemaker implantation without evidence of bacterial endocarditis. A case report].
Tricuspid stenosis related to endocardial pacemaker leads is uncommon. We report the case of a patient with severe tricuspid stenosis documented 15 years after the implantation of a permanent DDD pacemaker for symptomatic congenital heart block. The atrial and ventricular leads both had a loop at the level of the tricuspid valve that may have caused endothelial damage and, eventually, tricuspid...

Pacemaker infection has multiple risk factors. Its presentation is most often similar to infected endocarditis and the diagnosis is made through studying blood cultures. Transesophageal echocardiography can confirm the diagnosis. The most common microorganisms are staphylococcus speciesis. As a matter of fact, complete pacemaker removal appears to be the only definite treatment. We presented a ...
متن کاملLuminal vena cava superior and right atrial obstruction associated with severe tricuspid valve stenosis due to endocardial pacemaker leads: an extremely rare complication of permanent pacemakers.
In this report, we describe a case with severe tricuspid stenosis associated with partial luminal obstruction of the right atrium and vena cava superior secondary to transvenous pacemaker leads in a 49-year-old patient who had a permanent pacemaker implanted 17 years ago. The patient had no specific symptoms related to above findings; however, after clinical suspicion, transthoracic and transoe...
