Introduction:

tricuspid valve infectious endocarditis (IE) is rare and is associated with older patients, intravenous drug users or patients requiring intracardiac devices, catheters or prostheses, human immunodeficiency virus infection, diabetes mellitus (DM), neoplasms and hemodialysis.

Case presentation:

a case report of a 31-year-old woman with a history of health, who was admitted for prolonged febrile syndrome and anemia under study, is described; On admission, signs of heart failure were found, predominantly right, with arterial hypertension and diabetes mellitus onset.

Discussion:

tricuspid valve infective endocarditis was confirmed by Staphylococcus aureus. Serious complications such as: heart failure, recurrent bacterial bronchopneumonia due to pulmonary septic emboli, acute renal failure due to acute glomerulonephritis and acute tubular necrosis; Hemolytic anemia and acute neuroretinitis due to vasculitis or septic brain embolus characterized its torpid evolution. It required hemodynamic support and successful cardiopulmonary resuscitation after multiple cardiorespiratory stops due to polymorphic sustained ventricular tachycardia and ventricular fibrillation due to severe internal environment disorders and sepsis. Ampicillin 12 grm / day e.v + rifampicin 600 mg / day v.o for 6 weeks, was effective in eliminating septicemia.

Conclusions:

surgical treatment was applied (valvular replacement by metallic tricuspid prosthesis) without complications.
