Abstract

Introduction: Subacute Bacterial Endocarditis (SBE) is a slowly developing type of infective endocarditis. Aneurysm is more common in this type of endocarditis. Currently, SBE is an uncommon cause of unexplained fever (FUO) because rapid diagnostic capabilities, such as echocardiography, have improved. Despite echocardiography, endocarditis and valvular aneurysm were missed in our patient due to the location and special shape of the aneurysm near the annulus.

Case representation: We present a case of SBE resulting in an isolated ruptured mycotic mitral valve aneurysm in a patient on dialysis. Mycotic mitral valve aneurysm is an uncommon and serious complication of infective endocarditis, particularly subacute endocarditis.

Conclusion: In order to diagnose this complication, there should be clinical suspicion in the presence of severe regurgitation without any cause, and a detailed echocardiography should be performed.

被误诊为二尖瓣瓣环钙化的孤立性霉菌性二尖瓣破裂动脉瘤

简介亚急性细菌性心内膜炎（SBE）是一种发展缓慢的感染性心内膜炎。动脉瘤在这种类型的心内膜炎中更为常见。目前，由于超声心动图等快速诊断能力的提高，SBE 已成为不明原因发热（FUO）的罕见病因。尽管进行了超声心动图检查，但由于瓣环附近动脉瘤的位置和特殊形状，我们的患者还是漏诊了心内膜炎和瓣膜动脉瘤：我们介绍了一例在透析患者中因孤立的霉菌性二尖瓣动脉瘤破裂而导致 SBE 的病例。霉菌性二尖瓣动脉瘤是感染性心内膜炎，尤其是亚急性心内膜炎的一种不常见的严重并发症：结论：为了诊断这种并发症，临床上应怀疑无任何原因的严重瓣膜反流，并进行详细的超声心动图检查。
