Hypertrophic Cardiomyopathy or HCM is a heart condition where the heart muscle thickens abnormally. This thickening can occur in different parts of the heart, but usually occurs within the left ventricle, the main pumping chamber of the heart. Hypertrophic means "excessive growth" and  cardiomyopathy means "heart muscle disease." This thickening usually does not compromise the pumping or squeezing action of the heart, but can make it less compliant and slower to fill up with blood.  The thickening usually occurs in the ventricular septum which is the area of the heart that separates the right side from the left side of the heart and may interfere with the normal functioning of the heart by:
