Native Aortic Valve Infective Endocarditis Secondary to Community-Acquired Methicillin-Resistant Staphylococcus aureus: A Case Report and Literature Review

Infective endocarditis (IE) refers to a microbial infection affecting either a heart valve or endocardium, resulting in tissue damage and the formation of vegetation. Native aortic valve endocarditis in children is rare and is associated with serious complications related to valvular insufficiency and systemic embolizations. As reports about community-acquired methicillin-resistant Staphylococcus aureus (MRSA) native aortic valve endocarditis in children are very scarce, we report this case along with a literature review about its complications and management. Here, we report the case of a seven-month-old infant who was previously healthy and presented with signs and symptoms of shock and systemic embolizations secondary to native aortic valve IE. His blood culture showed MRSA. He developed aortic valve insufficiency heart failure and multiorgan septic emboli that progressed to fatal refractory multiorgan failure. The management of complicated aortic valve endocarditis in children is challenging and needs a multidisciplinary team approach and prompt intervention.

Adjunctive rifampin therapy for native valve Staphylococcus aureus endocarditis in a neonate: A case report and literature review

Infective endocarditis in neonates can be fatal. Adjunctive rifampin therapy might be effective as salvage therapy in critically ill patients with Staphylococcus aureus native valve endocarditis (NVE). We present a case of a full-term neonate with NVE who had a favorable clinical outcome after adding rifampin to standard therapy.
