Systolic anterior motion of the mitral valve is a mechanism for the development of left ventricular outflow tract (LVOT) obstruction. While often associated with left ventricular hypertrophy (LVH), a case is reported of symptomatic LVOT obstruction due to intrinsic mitral valve pathology in the absence of hypertrophy or cardiomyopathy. This case highlights the importance of recognizing isolated mitral valve pathology as a treatable cause of LVOT obstruction.
二尖瓣收缩期前向运动是左心室流出道（LVOT）梗阻形成的一种机制。虽然通常与左心室肥厚（LVH）相关，但有一例报告显示，在没有肥厚或心肌病的情况下，由于二尖瓣本身的病变导致了有症状的LVOT梗阻。该病例强调了认识到孤立的二尖瓣病变是LVOT梗阻可治疗病因的重要性。
