We report an unusual case of left ventricular outflow tract obstruction caused by accessory mitral valve tissue. This case illustrates the importance of transthoracic echocardiography in preoperative evaluation and the usefulness of transesophageal echocardiography for intraoperative assessment. If the accessory mitral valve has no functional significance it may be surgically excised, thereby relieving the outflow tract obstruction.
我们报告了一例由二尖瓣附属组织引起的左心室流出道梗阻的罕见病例。该病例说明了经胸超声心动图在术前评估中的重要性以及经食管超声心动图在术中评估中的实用性。如果二尖瓣附属组织无功能意义，可通过手术切除，从而解除流出道梗阻。
