Abstract

BackgroundStreptococcus bovis is a classical etiology of endocarditis and is associated with colonic lesions. No series of cases from Brazil has been described.ObjectivesTo describe aspects of S. bovis endocarditis.MethodsThis is a case series of patients admitted to a cardiac surgery referral center, during the years 2005–2014. Clinical, laboratory, echochardiographic, colonoscopic, treatment, surgical and outcome variables were studied.ResultsNine patients with S. bovis endocarditis were included; all cases fulfilled the modified Duke criteria. Incidence was 8/220 (4%) in years 2006–2014. There were seven male and two female patients; mean age was 56.7 years, standard deviation 13.4. All patients had native aortic valve involvement. Presentation was subacute in 7/9 (71%). Fever was present in 7/9 (77.7%), embolic lesions to solid organs occurred in three, and perivalvular abscess in two patients. All echocardiograms showed moderate to severe valvular regurgitation and vegetations. Microcytic anemia was seen in 7/7 patients. Colonoscopy showed abnormal findings in 7/9 (77.7%). Surgery was indicated for 6/9 patients due to acute aortic regurgitation and left ventricular failure. All patients were discharged home.ConclusionsS. bovis most frequently affected the aortic valve of male patients. Colon disease was frequent. Surgery was indicated frequently due to hemodynamic compromise.
