Case Report: Native aortic valve Listeria monocytogenes endocarditis in an adult with Evans syndrome

This case likely represents the first reported instance of native-valve <i>Listeria monocytogenes</i> endocarditis in a patient with Evans syndrome. It highlights prolonged immunosuppression in Evans syndrome as a potential risk context for invasive listeriosis with cardiac involvement. Early blood culture, routine echocardiographic evaluation for <i>Listeria</i> bacteremia, and timely targeted therapy are essential for optimizing patient outcomes.
