First-pass stress perfusion MR Imaging findings of apical hypertrophic cardiomyopathy: with relation to LV wall thickness and late Gadolinium-enhancement

Abstract

Hypertrophic cardiomyopathy (HCM) is a complex and common genetic cardiac disease and it is a primary disease of the cardiac muscle that typically displays a marked and diffuse pattern of ventricular wall thickening (1). A variant apical form of HCM is characterized by wall thickening confined to the ventricular apex, with a typical ‘ace of spade’ configuration (2, 3).
