RESUMO
We presented two non-addicted patients with Tricuspid valve endocarditis. The first patient was a 38-year-old diabetic female with; fever chills, anemia, and microscopic hematuria and pyuria that occurred during several weeks. The plain radiography of chest was normal and high resolution computed tomography [HRCT] of chest, was done because of predominant pulmonary symptoms and signs that revealed consolidation and cystic formation in the left parynchyma. Based on these findings in HRCT we decided to start anti-tuberculosis treatment, but no significant response was seen. Tran's Thoracic Echocardiography [TTE] was done and revealed large vegetation of Tricuspid valve. The second patient was a 45 -year-old man who admitted with acute fever and left lower lobe infiltrate and systolic murmur. TTE was normal but Trans Esophageal Echocardiography showed large vegetation on the Tricuspid valve. Staphylococcus aurous grew in 2/3 blood cultures. We suggest that right-sided endocarditis must be considered in any patient with fever and recurrent pulmonary symptoms and signs, with or without abnormal chest X- ray, heart murmur or intravenous drug addiction
