Accessory mitral valve tissue, a rare cause of left ventricular outflow tract obstruction, can be difficult to diagnose preoperatively and confusing even at surgery. The reported case illustrates how preoperative evaluation can be made using two-dimensional echocardiography combined with Doppler flow analysis. The intraoperative technique for removing the accessory tissue without causing damage to the native mitral valve is discussed.
二尖瓣附属组织是左心室流出道梗阻的罕见原因，术前诊断可能困难，甚至在手术时也容易混淆。报道的病例说明了如何使用二维超声心动图结合多普勒血流分析进行术前评估。文中还讨论了在不损伤天然二尖瓣的情况下切除附属组织的术中技术。
