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.
