Resumo
Background: Streptococcus bovis is a classical etiology of endocarditis and is associated withcolonic lesions. No series of cases from Brazil has been described.Objectives: To describe aspects of S. bovis endocarditis.Methods: This is a case series of patients admitted to a cardiac surgery referral center, dur-ing the years 2005–2014. Clinical, laboratory, echochardiographic, colonoscopic, treatment,surgical and outcome variables were studied.Results: Nine patients with S. bovis endocarditis were included; all cases fulfilled the modifiedDuke criteria. Incidence was 8/220 (4%) in years 2006–2014. There were seven male andtwo female patients; mean age was 56.7 years, standard deviation 13.4. All patients hadnative aortic valve involvement. Presentation was subacute in 7/9 (71%). Fever was presentin 7/9 (77.7%), embolic lesions to solid organs occurred in three, and perivalvular abscessin two patients. All echocardiograms showed moderate to severe valvular regurgitation andvegetations. Microcytic anemia was seen in 7/7 patients. Colonoscopy showed abnormalfindings in 7/9 (77.7%). Surgery was indicated for 6/9 patients due to acute aortic regurgitationand left ventricular failure. All patients were discharged home.Conclusions: S. bovis most frequently affected the aortic valve of male patients. Colon diseasewas frequent. Surgery was indicated frequently due to hemodynamic compromise
