Tricuspid stenosis: a rare complication of pacemaker-related endocarditis.

We report a case of recurrent pacemaker lead endocarditis as the cause of acquired tricuspid stenosis. The diagnosis was made noninvasively by 2-dimensional Doppler echocardiography. The case was further complicated by a paradoxical septic embolism through a patent foramen ovale. This cascade of rear events after a pacemaker implantation has never been described in the literature before.
