[Transesophageal echocardiographic evaluation of tricuspid endocarditis from implanted pacemaker: description of two cases]. / Valutazione con ecocardiografia transesofagea dell'endocardite tricuspidale da impianto di pacemaker: descrizione di due casi.

Two cases of tricuspid valve endocarditis due to staphylococcus epidermidis have been examined in patients with permanent transvenous pacemaker. While transthoracic echocardiography was unable to detect any tricuspidal abnormalities, large vegetations located on the tricuspidal leaflets and the electrocatheter were detected by transesophageal echocardiography. Both cases required surgical removal of the electrostimulation system and valve toilet.
