Sumario:Patient: Female, 76-year-old Final Diagnosis: Mitral valve vegetation with Pasteurella multicoda Symptoms: Generalized malaise Medication:— Clinical Procedure: — Specialty: Cardiology • Geriatrics OBJECTIVE: Unusual clinical course BACKGROUND: As a common member of the oral bacterial flora of cats and dogs, Pasteurella multocida can cause skin and soft tissue infection in humans after bites, licks, or scratches from animals. Uncommonly, infection due to Pasteurella can cause sepsis in humans. Even more rare is the development of infectious endocarditis from a Pasteurella infection. CASE REPORT: A 76-year-old woman presented with malaise and symptoms of fluid overload. Blood cultures were positive for Pasteurella multocida, and an echocardiogram was significant for mitral valve vegetation and severe biatrial enlargement. A diagnosis of Pasteurella endocarditis was made. Surgical intervention was recommended, but owing to the risk involved, the patient elected for conservative management involving long-term treatment with intravenous antibiotics. CONCLUSIONS: While exceedingly rare, Pasteurella multocida can cause infectious endocarditis in patients with predisposing factors. This patient had a known history of rheumatic heart disease, which is believed to have caused the significant findings on imaging. To the best of our knowledge, our case is the only one to depict Pasteurella endocarditis in a patient with rheumatic heart disease and severe biatrial enlargement. It is the authors’ belief that the rheumatic heart disease and remodeling of the heart increased her susceptibility to severe infection from Pasteurella. The purpose of this case is to describe the pathogenicity of an otherwise low-attack bacterial infection in an elderly patient with underlying structural acquired heart damage.
