Hypertrophic Cardiomyopathy

Hypertrophic cardiomyopathy (HCM) is an inherited condition that causes thickening of the walls of the left ventricle, the main pumping chamber of the heart. In some people, the heart becomes stiff and cannot fill properly or pump enough blood to provide an adequate supply to the body, particularly during exercise. In the majority of people with this condition, blood flow from the heart is obstructed. This condition may be associated with potentially dangerous irregular heart rhythms.

Cardiologists and heart surgeons at NYU Langone’s Hypertrophic Cardiomyopathy Program are pioneers in the medical and surgical treatment of this condition and have cared for more than 2,500 people. Our doctors work with specialists from our Heart Rhythm Center—including electrophysiologists, who specialize in heart rhythm disorders, and cardiac device management doctors—to care for people with the condition. Our experts also provide genetic counseling and testing for family members of people with HCM.
