Reminder of important clinical lesson: Lost without Occams razor: Escherichia coli tricuspid valve endocarditis in a non-intravenous drug user

摘要

The unusual case of a 31-year-old woman who developed tricuspid valve endocarditis with positive blood cultures for Escherichia coli is presented. The patient had no underlying cardiac disease or predisposing conditions that could have made her susceptible to the native valve infection. Despite a lengthy course of intravenous antibiotics only a partial response was achieved. The patient underwent cardiac surgery and had a good postoperative recovery.
