Development of obstructive hypertrophic cardiomyopathy from nonobstructive hypertrophic cardiomyopathy

Am J Cardiol. 1998 Aug 1;82(3):403-5. doi: 10.1016/s0002-9149(98)00337-3.

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.
