Mitral valve aneurysm is a rare abnormality whose pathophysiology is poorly understood. It is defined as a bulge of the mitral valve leaflet toward the left atrium. Aneurysm in the posterior leaflet is exceptional. We report the case of a 26-year old man, who had been followed up for rheumatic aortic regurgitation for 4-years, hospitalized for febrile syndrome associated with episodes of left heart failure. Transthoracic echocardiographic examination (TTE) and transesophageal echocardiography (TEE) showed aortic valve vegetations with wide aneurysm of the small mitral valve associated with severe mitral valve regurgitation. The patient underwent mitral and aortic valve replacement with simple postoperative outcome. Clinical suspicion associated with suitable preoperative imaging and early surgical treatment are essential to recognize and treat this rare complication of infectious endocard.
二尖瓣动脉瘤是一种罕见的异常情况，其病理生理学尚未完全了解。它被定义为二尖瓣叶向左心房的膨出。后叶的动脉瘤非常罕见。我们报告一例26岁男性病例，该患者因风湿性主动脉瓣反流接受了4年的随访，因与左心衰竭发作相关的发热综合征住院。经胸超声心动图检查（TTE）和经食管超声心动图（TEE）显示主动脉瓣赘生物，伴有小型二尖瓣的广泛动脉瘤，合并严重二尖瓣反流。该患者接受了二尖瓣和主动脉瓣置换术，术后恢复良好。临床怀疑结合适当的术前影像学检查和早期手术治疗对于识别和治疗这种感染性心内膜炎的罕见并发症至关重要。
