Tricuspid Valve Infective Endocarditis Due to Klebsiella pneumoniae in Intravenous Drug User

摘要

Infective endocarditis is a high morbidity-mortality condition despite advancements in supportive care and medical therapy. One of the strongest risk factors is intravenous drug use, which has high prevalence in the Hawaii population. Klebsiella pneumoniae is a rare but aggressive pathogen causing infective endocarditis. There is no strong evidence to guide management. We present a rare case of isolated tricuspid valve infective endocarditis due to Klebsiella pneumoniae in an intravenous drug user causing septic pulmonary emboli and multiple abscesses. The patient was managed with combined 6-week ceftriaxone and 2-week gentamicin together with early tricuspid valve repair.
