Accessory mitral valve tissue (AMVT) is a rare congenital cardiac anomaly, which is associated with other congenital heart diseases. It is diagnosed in neonates or childhood and rarely in adulthood. Nevertheless, AMVT is an incidental finding or described as isolated. Echocardiography, especially three-dimensional echocardiography is considered as an optimal imaging technique for AMVT diagnosis. We herein presented an asymptomatic adult AMVT cases with significant left ventricular outflow tract obstruction and surgical excision was recommended.
瓣下二尖瓣组织（Accessory mitral valve tissue，AMVT）是一种罕见的先天性心脏畸形，常与其他先天性心脏病相关。它通常在新生儿或儿童时期被诊断出来，很少在成年后被发现。然而，AMVT 也可能是偶然发现的，或者被描述为孤立性的。超声心动图，尤其是三维超声心动图，被认为是 AMVT 诊断的最佳影像学技术。本文报告了一例无症状的成人 AMVT 病例，该病例存在明显的左心室流出道梗阻，建议进行手术切除。
