Left Ventricular Outflow Tract Obstruction and Systolic Anterior Motion of the Mitral Valve in the Absence of Hypertrophic Cardiomyopathy.

ABSTRACT

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.
