Infective endocarditis is one of the uncommon causes of complete atrioventricular (AV) block. Complications from aortic valve infection are more often associated with conduction abnormalities than with mitral valve endocarditis. In fact, complete AV block rarely occurs in mitral valve infections, with only a few cases having been reported. We report a case of mitral valve endocarditis in which the initial presentation was fever and newly developed, complete AV block. Patients with mitral valve endocarditis complicated by complete AV block are at high risk. Prompt investigation, administration of appropriate antibiotics and consideration of early surgical intervention are needed.
感染性心内膜炎是完全性房室传导阻滞的罕见病因之一。主动脉瓣感染的并发症比二尖瓣心内膜炎更常与传导异常相关。事实上，完全性房室传导阻滞在二尖瓣感染中很少发生，仅有少数病例报道。我们报告一例二尖瓣心内膜炎病例，其最初表现为发热和新出现的完全性房室传导阻滞。合并完全性房室传导阻滞的二尖瓣心内膜炎患者风险很高。需要及时进行检查、给予适当抗生素并考虑早期手术干预。
