ABSTRACT
Endocarditis due to Streptococcus gallolyticus, an agent previously included in the Streptococcus bovis denomination is a serious disease, often associated with lesions of the colon mucosa. Aortic valve is more often affected and tricuspid involvement is quite rare. We present a case of a 56-year-old man who was admitted with a 2-month history of fever. Echocardiogram revealed vegetations on the aortic and tricuspid valve and blood cultures grew S. gallolyticus. Thoracic X-ray and computed tomography were consistent with septic pulmonary embolism. Despite optimal antibiotic therapy he developed an ischemic stroke and acute aortic regurgitation, which led to emergent surgery. Colonoscopy found a benign adenoma which was excised, and the patient had a full recovery.
