Hypertrophic cardiomyopathy (HCM) is a genetic and familial cardiovascular disease which can cause severe arrhythmia and heart failure. With irregular hypertrophy and disorganized arrangement of cardiomyocytes on histological picture, the normal myocardium macrostructure appears in whole or part as ventricular wall thickness, especially ventricular septal thickness (1).
