title: Chiari network endocarditis: not just an innocent bystander.
abstract: A Chiari's network, noted in approximately 2% of the general population, is a congenital remnant of the sinus venosum valve present in the right atrium. We report a case of a 67-year-old male who presented with acute infective endocarditis of the tricuspid valve due to coagulase-negative Staphylococci. Despite appropriate antimicrobial therapy for 2 weeks, the patient remained febrile with septic emboli to the pulmonary vasculature. Repeat transthoracic echocardiography (TTE) revealed persistent vegetations adherent to the tricuspid valve, extending onto the Chiari network, necessitating surgical intervention.
