[Isolated tricuspid valve infective endocarditis in a patient with a urological history].

Infective endocardits of the tricuspid valve (TVIE) occurs mainly in addicted-intravenous drug users, in the presence of intracardiac electrodes or central venous catheters, and in some congenital heart diseases; rarely, in other conditions. The authors present a case of a 61-year-old male with TVIE as a result of complicated transurethral resection of bladder papilloma. The onset of TVIE was insidious, with low back pain, followed by pulmonary symptoms. Echocardiography showed large vegetations on the tricuspid valve; blood culture was positive for methycylin-resistant, coagulase-negative staphylococcus. Fever remission and negative bacteriological blood examination results were achieved following treatment with linezolid; however, because of advanced tricuspid valve destruction, valve replacement was necessary.
