Overview
Hypertrophic Cardiomyopathy is defined by LV hypertrophy associated with nondilated ventricular chambers without any other cardiac or systemic disease that itself would be capable of producing the magnitude of hypertrophy evident. HCM is usually recognized by maximal LV wall thickness ≥15 mm. Wall thickness of 13 to 14 mm is considered borderline if there are other compelling information (eg, family history of HCM), based on echocardiography. The diagnostic imaging mainly focused on echocardiography, however cardiovascular magnetic resonance (CMR) is used with increasing frequency.[1]
