The combination of the systolic anterior motion of the anterior leaflet of the mitral valve and/or the mitral annular calcification in the case of asymmetrical septal hypertrophy has been fully recognized. However, in concentric left ventricular hypertrophy the systolic anterior motion of the anterior mitral valve and the massive posterior submitral calcification have not been commonly reported. We present a case with mild concentric left ventricular hypertrophy and massive posterior submitral calcification which displace the entire mitral ring anteriorly, namely, toward the left ventricular outflow tract. In this case, typical left ventricular outflow obstruction with systolic anterior motion of the anterior mitral valve was seen. Thus, we considered that this rare condition may have contributed to the formation of the systolic anterior motion of the anterior mitral leaflet in this case. We have provided additional information regarding the possible causes of systolic outflow obstruction in hypertrophic obstructive cardiomyopathy.
二尖瓣前叶收缩期向前运动和/或不对称性室间隔肥厚病例中的二尖瓣环钙化的联合情况已得到充分认识。然而，在同心性左心室肥厚中，二尖瓣前叶收缩期向前运动和二尖瓣后叶大量钙化尚未见普遍报道。我们报告一例轻度同心性左心室肥厚和二尖瓣后叶大量钙化的病例，后者将整个二尖瓣环向前移位，即朝着左心室流出道移位。在该病例中，可见典型的伴有二尖瓣前叶收缩期向前运动的左心室流出道梗阻。因此，我们认为这种罕见情况可能促成了该病例中二尖瓣前叶收缩期向前运动的形成。我们提供了有关肥厚型梗阻性心肌病收缩期流出道梗阻可能原因的更多信息。
