title: An atypical presentation of infective endocarditis.
abstract: Infective endocarditis is a well-known clinical entity. However, despite improved diagnostic techniques and advances in treatment options, left-sided native valve infective endocarditis remains a serious disease with high morbidity and mortality, especially in cases caused by Staphylococcus aureus. The clinical heterogeneity of infective endocarditis sometimes prevents rapid recognition, correct diagnosis and timely treatment, which are essential to reduce the morbidity and mortality associated with this disease. We report the case of a 62-year-old man, admitted for atrial fibrillation with complete atrioventricular block, which was found to be the result of methicillin-resistant S. aureus mitral valve endocarditis, complicated by local extension of the infection, heart failure, systemic embolism and multiple organ failure.
