What is Hypertrophic Cardiomyopathy?

Hypertrophic cardiomyopathy (HCM) is a genetic condition in which the muscle of the heart is abnormally large in the absence of an apparent cause. When the muscle of the left ventricle of the heart becomes thicker than normal, blood flow is obstructed to the rest of the body.

The thickening of the muscle can also affect the heart's mitral valve, which separates the left atrium and the left ventricle. When this happens, the mitral valve leaflets become leaky, allowing blood to move backwards from the left ventricle into the left atrium, instead of forward to the rest of the body.

About the Hypertrophic Cardiomyopathy Center at Stanford

The Hypertrophic Cardiomyopathy Center at Stanford Hospital & Clinics is specialized in the care of patients and families with hypertrophic cardiomyopathy and other forms of familial cardiomyopathy. From the latest imaging techniques to sophisticated genetic profiling, our team offers world class care with an emphasis on compassion and communication.

At Stanford Hospital & Clinics, we offer a variety of treatment options for hypertrophic cardiomyopathy. Stanford cardiologists are world leaders in the development of implantable cardioverter-defibrillator devices (ICDs). Our cardiac surgeons are pioneers in the development of the myotomy-myectomy procedure for patients with hypertrophic cardiomyopathy. Many new diagnostic tools and therapies are developed here and Stanford patients are often among the first to benefit when new treatments come to clinical trials.

In addition, Stanford cardiologists were among the first to perform alcohol septal ablation, a less invasive technique to remove thickened heart muscle which many patients consider. Here at Stanford Hospital & Clinics, we will help you make the best decision for your future care.

Stanford Hypertrophic Cardiomyopathy Center Services

Our team-based approach when treating patients involves genetic counselors, specialist nurses, cardiologists, and cardiac surgeons through our Stanford Center for Inherited Cardiovascular Disease. All are focused on giving you the best possible information to help clarify your diagnosis and maximize the treatment options available for you and your family.

Family Planning

At Stanford Hospital & Clinics, we aim to define the future management of hypertrophic cardiomyopathy. Stanford is world-renowned for research into the molecular genetics of cardiomyopathy. Our genetic counselors are also available to help patients with hypertrophic cardiomyopathy who are planning to have children.

Genetic Counseling

Patients with hypertrophic cardiomyopathy will meet with a genetic counselor. This meeting will include a discussion of what genetic testing is available for your condition and how such testing can help you and your family members. By reviewing your family history the genetic counselor will help you identify which family members are at risk to have the inherited cardiovascular condition that’s running in your family.

We will give you and your family recommendations for how to check for the development of heart problems in at-risk family members as well as any steps that can be taken to prevent heart problems. The genetic counselor can also provide support and counseling to help you and your family deal with the emotions that arise when someone in the family has an inherited condition.


Through close connections with the cardiology division of Lucile Packard Children's Hospital, we facilitate care across generations. If required, we can even coordinate center visits for you and your children.

Heart Transplant

The Stanford Heart Transplant program has the accumulated wisdom of more than 50 years of research and patient care experience. Our physicians and scientists work collaboratively with faculty from the Stanford School of Medicine to develop the latest advancements in the diagnosis and treatment of advanced heart failure and cardiomyopathy.

Inpatient Care

Your pre-operative, peri-operative, and post-operative care will be managed by our multidisciplinary team. Our team works together to ensure the best quality of care for you during your stay with us. This team includes surgeons, anesthesiologists, nursing staff, case managers, social workers, physical therapists, occupational therapists, respiratory therapists, pharmacists, and a dietitian.


We use a variety of advanced imaging tools to monitor your heart and determine your care plan. For example, an electrocardiogram helps us learn more about your heart rhythm and heart size. Through an echocardiogram, we are able to see your heart beating in real time, and watch how blood travels through the various heart valves. An MRI provides additional detail watching your heart at work.

Exercise Physiology

Hypertrophic cardiomyopathy often affects young and athletic individuals. We have close links with the Stanford Sports Medicine division and maintain an active interest in athletes with cardiovascular abnormalities and the appropriate screening of athletes pre-participation.
