Infective Endocarditis From Pseudomonas aeruginosa and Group C Streptococcus

Endocarditis is a condition that is usually caused by an infection or inflammation of the endocardium. The disease is commonly seen among intravenous drug abusers, patients with intravenous catheters, and those who undergo cardiovascular and invasive dental procedures. Multiple different pathogens can cause endocarditis (bacterial, fungal, and viral) depending upon the patient's risk factors, epidemiology, and bacteria that are prevalent/endemic to the region. We present the case of a woman who had a history of polysubstance abuse, having presented to the hospital on multiple occasions with bacteremia with a previous admission for endocarditis, who developed a multi-bacterial infection at this presentation involving Pseudomonas aeruginosa and group C Streptococcus, which affected both the right and left side of the heart. In this paper, we reviewed common presentations of endocarditis caused by either bacteria, as well as recommendations for medical or surgical management of the condition.
