A rare case of native mitral valve infective endocarditis presenting with complete heart block and intermittent atrial flutter

Abstract

Mitral valve infective endocarditis, without aortic involvement, is a rare cause of complete heart block. It is thought that infections placed close to the conductive system of the heart may drive a conduction block. We found six cases in the literature, via searching PubMed, of mitral valve infective endocarditis with complete heart block and no aortic involvement. We report a case of complete heart block with a junctional escape rhythm in a patient with a Staphylococcus Aureus vegetation on a native mitral valve only.
