Here we present a rare case of infective endocarditis (IE) with Streptococcus canis and Chiari network in an 85 year old female living with multiple dogs and open skin of lower extremity predisposing her to bacteremia. Underlying abnormalities of the cardiac chambers such as Chiari network predisposes to a higher incidence of bacterial seeding and causing IE. A Chiari network is usually asymptomatic and of no clinical significance but can worsen prognosis in IE. IE carries a significant morbidity and mortality burden and when diagnosed early can be a lifesaving diagnosis. Due to the wide range of complications, early diagnosis and treatment with targeted antimicrobial therapy and consideration of early surgical intervention are vital to the evaluation and treatment of IE. Though Staphylococci, Streptococci, Enterococci, HACEK organisms amount for the majority of IE, some atypical organisms including group G Streptococci such as S. canis have been reported to carry high mortality and hospitalization risk in patients with bacteremia. S. canis is a group G beta-hemolytic Streptococci which normally resides on the skin and mucosal surfaces of dogs. This Case Report shines light on the versatility of microorganisms that can cause IE in a patient with underling Chiari network, and the risk of morbidity and mortality with such species highlighting the importance of early diagnosis and treatment.
