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 underrecognised. 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.
