Abnormalities of the mitral valve apparatus are a phenotypical expression of hypertrophic cardiomyopathy and can contribute to systolic anterior motion and left ventricular outflow tract obstruction. In patients with significant abnormalities of the mitral apparatus, adjunct procedures like plication of the anterior mitral leaflet and/or release of papillary muscles may be required to obtain sufficient relief of obstruction. Very rarely, an elongated posterior mitral leaflet is the main culprit for systolic anterior motion. In such cases, plication of the posterior mitral leaflet is a useful technique, in addition to septal myectomy, to abolish left ventricular outflow tract obstruction.

二尖瓣装置异常是肥厚型心肌病的一种表型表现，可导致收缩期前向运动和左心室流出道梗阻。在二尖瓣装置存在明显异常的患者中，可能需要诸如二尖瓣前叶折叠和/或乳头肌松解等辅助手术来充分缓解梗阻。非常罕见的是，二尖瓣后叶过长是收缩期前向运动的主要原因。在这种情况下，除间隔心肌切除术外，二尖瓣后叶折叠术是消除左心室流出道梗阻的一种有用技术。
