Mitral valve aneurysm is defined as outpouching of the mitral valve which expands in systole and collapse in diastole. It was first reported in 1729 by Morand. Most of the cases have been described in the African population. It is rare in the Indian population. Its chief presentations are congestive heart failure, palpitations, arrhythmia, or in rare cases an embolic phenomenon. It can be diagnosed either by echocardiography or cardiac imaging (magnetic resonance imaging/computed tomography). It can either occur as an isolated defect or with other associated valvular abnormalities. Here, we present a case of a 40-year-old male who was referred for the evaluation of palpitation who on the investigation was found to have a bicuspid aortic valve with severe Aortic Regurgitation (AR) along with aneurysm in the anterior mitral leaflet causing severe mitral regurgitation. This case highlights the importance of keeping a submitral aneurysm as a differential diagnosis for mitral regurgitation and searching for other associated valvular defects which may affect the management and treatment outcomes.
二尖瓣瘤是指二尖瓣向外膨出，在收缩期扩张，在舒张期塌陷。它于 1729 年由 Morand 首次报道。大多数病例发生在非洲人群中。在印度人群中很少见。其主要表现为充血性心力衰竭、心悸、心律失常，或在极少数情况下出现栓塞现象。它可以通过超声心动图或心脏成像（磁共振成像/计算机断层扫描）来诊断。它可以作为一个孤立的缺陷或与其他相关的瓣膜异常同时发生。在这里，我们介绍了一个 40 岁男性的病例，他因心悸就诊，经检查发现他有二叶式主动脉瓣，并伴有严重的主动脉瓣反流（AR），同时前二尖瓣叶有动脉瘤，导致严重的二尖瓣反流。这个病例强调了将瓣下型动脉瘤作为二尖瓣反流的鉴别诊断的重要性，并寻找其他可能影响管理和治疗结果的相关瓣膜缺陷。
