A case of mitral regurgitation (MR) caused by mitral paraannular cyst is reported. A 37-year-old woman on maintenance hemodialysis was admitted to Akita University Hospital because of congestive heart failure. Echocardiography revealed mitral paraannular cyst, which caused coaptation failure of the mitral leaflets and significant MR. She underwent decapsulation of the cyst followed by mitral valve replacement. Postoperative echocardiography showed no recurrence of the cyst three years after surgery. Although mitral annular calcification has been described as a cause of MR in patients with uremia, a report of a solitary intracardiac cyst which causes significant MR is quite rare.
报告了一例由二尖瓣环旁囊肿引起的二尖瓣反流（MR）病例。一名37岁维持性血液透析的女性因充血性心力衰竭入住秋田大学医院。超声心动图显示二尖瓣环旁囊肿，导致二尖瓣叶对合失败和严重的MR。她接受了囊肿剥除术，随后进行了二尖瓣置换术。术后三年的超声心动图显示囊肿未复发。虽然二尖瓣环钙化已被描述为尿毒症患者MR的一个原因，但关于导致严重MR的孤立性心内囊肿的报道非常罕见。
