Multisystem organ failure secondary to Haemophilus parainfluenzae infective endocarditis on an ICD lead: A case report.

Infection of implanted cardiac devices (ICD) is an unusual but life threatening event, rarely caused by Haemophilus parainfluenzae. While clinical presentation varies widely, infective endocarditis (IE) involving an ICD lead requires aggressive resuscitation and a multidisciplinary approach. We present a case of a 33-year-old intravenous drug user who presented in multisystem organ failure secondary to infective endocarditis on an ICD lead.
