myocardial disease characterized by hypertrophy, involving mainly the interventricular septum, interfering with left ventricular emptying.
A condition in which the myocardium is hypertrophied without an obvious cause. The hypertrophy is generally asymmetric and may be associated with obstruction of the ventricular outflow tract.

condition in which there is a deviation from or interruption of the normal structure or function of the myocardium, the middle and thickest layer of the heart wall, composed of heart muscle.
