Abstract

Redundant or accessory mitral valve tissue (AMVT) is a rare clinical condition. It is an even rarer cause of left ventricular outflow tract obstruction. We report a case of an adult male with medically unresponsive hypertrophic obstructive cardiomyopathy in whom real-time three-dimensional transesophageal echocardiography was used to both diagnose the presence of coexistent asymmetric septal hypertrophy and AMVT as well as confirm the safety and efficacy of treatment with alcohol septal ablation.

摘要

多余或副二尖瓣组织（AMVT）是一种罕见的临床病症。它是左心室流出道梗阻更为罕见的病因。我们报告一例成年男性患者，其患有药物治疗无效的肥厚性梗阻性心肌病，采用实时三维经食管超声心动图诊断出并存不对称性室间隔肥厚和AMVT，并证实了酒精室间隔消融治疗的安全性和有效性。
