Abstract

Infective endocarditis on a native aortic valve caused by Streptococcus bovis is a serious condition associated with severe complications and a notable relationship with gastrointestinal neoplasms. This study aims to report a clinical case highlighting the importance of thorough evaluation and a multidisciplinary approach in its management. A 35-year-old patient presented with progressive dyspnea and edema, without a history of heart disease. Physical examination and initial tests indicated heart failure, and echocardiography revealed vegetation on the aortic valve. Intravenous antibiotic treatment was initiated, and due to hemodynamic instability, Bentall/Bono surgery was performed to replace the aortic valve and ascending aorta. Valve culture confirmed Streptococcus bovis, and antibiotic therapy was maintained for 35 days. A subsequent outpatient colonoscopy identified colonic polyps related to benign neoplasms. This case underscores the need for early diagnosis, aggressive treatment, and multidisciplinary follow-up in patients with infective endocarditis, especially due to the association with gastrointestinal pathologies. The findings emphasize the importance of clinical vigilance and the integration of different medical specialties to optimize outcomes and improve patient quality of life.
