All types of Streptococcus bovis infection have been related to the presence of a gastrointestinal neoplasia, which in most cases is colonic adenoma or carcinoma. We report the case of a patient who was diagnosed with villous adenoma of the colon and underwent aortic valve replacement because of a large vegetation on the aortic valve caused by Streptococcus Bovis endocarditis.48 years old male patient with a history of abdominal pain and weight loss for the last 1.5 months was diagnosed with villous adenoma. 1 week after his colonoscopy the patient presented to our clinic with tachycardia, fever, fatique, and swelling of the feet. In echocardiographic evaluation a 4.5x1.1 cm mobile mass filling the aortic lumen almost totally and reaching the mitral valve region and 3rd degree aortic regurgitation was found. The postoperative course was uneventful. After the first postoperative month the patient was transferred to general surgery clinic. Streptococcus Bovis endocarditis is normaly very uncommon. Since Streptococcus Bovis endocarditis is strongly associated with emboli, urgent operation should be planned and the vegetation should be removed.Englishgentamicinvancomycinabdominal painadultaorta valve regurgitationaorta valve replacementarticlebacterial endocarditiscardiopulmonary bypasscase reportcolonoscopyechocardiographyfatiguefeet swellingfeverhumanmaleoperation durationpostoperative periodStreptococcus bovissurgical techniqueswellingtachycardiatreatment responsevillous adenomaweight reductionArticle
