Dr. Mark Milunski
Cardiology 37 years experience
HCM: Hcm is an abnormal thickening usually of the wall (septum) that divides the right and left ventricle. This thickening occurs in the absence of other diseases known to cause thickening of the heart muscle. It is relatively uncommon but occurs in a familial/hereditary form more than 50% of the time. Therefore, siblings and children of patients with hcm should be screened for it.

Dr. James Chen
Sports Medicine 15 years experience
HCM: Hypertrophic cardiomyopathy is a rare condition of the actual muscle of the heart becoming so large and thick as to obstruct outgoing blood flow. Because outgoing flow is reduced the heart must work even harder to pump blood to supply oxygen to the body. It is notable because patients are usually asymptomatic but can initially present with sudden collapse or even death.
