Hypertrophic cardiomyopathy (HCM) occurs when the heart muscle thickens over time. This thickening usually occurs in the left ventricle, the chamber of the heart responsible for pumping oxygen-rich blood to the body. HCM may affect the heart in various ways. In some people, this thickening or related mitral valve abnormalities, block the flow of blood from the heart, leading to symptoms. In others, the thickened muscle limits the ability of the heart to pump a normal ammount of blood, by restricting the size of its chamber or its ability to relax. HCM also increases the chance that a person will have irregular heart rhythms (arrhythmias), which can be life-threatening.
With the right care, most people can have a full life and avoid the life-threatening complications that can arise when hypertrophic cardiomyopathy is not properly identified and managed.
Our world-renowned hypertrophic cardiomyopathy center of excellence contributes to the latest clinical research on HCM. Our doctors have pioneered many HCM treatments and continue to improve care by testing new therapies and exploring genetic causes of this cardiomyopathy. We specialize in expert interpretation of genetic testing, which can provide crucial treatment guidance and protect your family.
