A man in his mid-50s presented to the hospital with malaise, fevers, hypotension, and altered mental status. Three months prior, he had an episode of native aortic valve endocarditis, necessitating aortic valve replacement with a pericardial bioprosthesis. He developed postoperative acute renal failure, which progressed to chronic renal failure requiring dialysis via tunneled catheter. On this admission, he was found to have methicillin-resistant Staphylococcus aureus (MRSA) bacteremia. Transesophageal echocardiography demonstrated a vegetation on his prosthetic aortic valve. He was diagnosed as having MRSA prosthetic valve endocarditis and admitted to the cardiovascular surgical intensive care unit prior to surgical intervention.
