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.
二尖瓣感染性心内膜炎,无主动脉受累,是完全性心脏传导阻滞的罕见病因。据认为,靠近心脏传导系统的感染可能导致传导阻滞。通过检索PubMed,我们在文献中发现了6例二尖瓣感染性心内膜炎合并完全性心脏传导阻滞且无主动脉受累的病例。我们报告1例仅在天然二尖瓣上有金黄色葡萄球菌赘生物的患者发生完全性心脏传导阻滞并伴有交界性逸搏心律。
