## Abstract

We report a case of a 16-year-old male with tricuspid valve infective endocarditis caused by Aggregatibacter aphrophilus and complicated by pulmonary septic embolisms. Multiple antimicrobial therapy was unsuccessful and surgical management was required. In this report, the authors highlight the importance of a high index of suspicion regarding the diagnosis of endocarditis and its possible complications.
