Abstract
A rare case of obstructive hypertrophic cardiomyopathy (HC) with mitral regurgitation (MR) is reported, which developed over 7 years from nonobstructive HC in an elderly woman. Systolic anterior motion of the anterior mitral leaflet was the most likely cause of the outflow obstruction and mitral valve replacement combined with septal myectomy resulted in complete abolition of the outflow tract gradient and MR.
摘要
报告了一例罕见的伴有二尖瓣反流（MR）的梗阻性肥厚型心肌病（HC）病例，该病例在一名老年女性中由非梗阻性HC发展了7年。二尖瓣前叶收缩期前向运动是流出道梗阻最可能的原因，二尖瓣置换术联合室间隔心肌切除术导致流出道压差和二尖瓣反流完全消除。
