Abstract

PVE (Prosthetic valve endocarditis) is a rare but potentially fatal side effect of valve surgery. Escherichia coli (E. coli) is a very uncommon cause of endocarditis; thus far, only 11 cases have been reported. In this case report, we present an interesting case of a rare E. coli prosthetic valve infective endocarditis (IE) in a 73-year-old man, which was successfully treated with Ceftriaxone without cardiac surgery. We summarize the previous cases alongside highlighting the difficulty in diagnosing PVE with transesophageal echocardiography.
