Hypertrophic cardiomyopathy (HCM) is a complex type of heart disease that affects the heart muscle. HCM causes thickening of the heart muscle (especially the ventricles, or lower heart chambers), left ventricular stiffness, mitral valve changes and cellular changes.
At Cleveland Clinic's Miller Family Heart, Vascular & Thoracic Institute, we have a special interest in treating Hypertrophic Cardiomyopathy (HCM). Since 1978, we have treated thousands of patients and the numbers are increasing each year.
What We Treat
Cleveland Clinic's Hypertrophic Cardiomyopathy Center is a multidisciplinary specialty treatment group dedicated to the diagnosis and treatment of HCM in individuals and family members. We bring together clinicians that specialize in HCM, including physicians and nurses from Cardiovascular Medicine, Genetics, Cardiothoracic Surgery, Pediatric Cardiology, and Psychology with expertise in diagnostic and genetic testing, medical management, and interventional and surgical procedures for patients with obstructive hypertrophic cardiomyopathy. In addition, we are involved in multiple research studies that provide patients with access to cutting edge novel therapies and diagnostic modalities.new method of diagnostic testing.

Why choose Cleveland Clinic for your care?
Our outcomes speak for themselves. Please review our facts and figures and if you have any questions don't hesitate to ask.

Our Medical Team
Cardiovascular Medicine and Imaging
Cardiovascular specialists use the latest techniques, such as tissue Doppler imaging, color M-Mode Doppler, transesophageal echocardiography, MR and CT help to diagnose hypertrophic cardiomyopathy and determine the best treatment. This group of physicians will evaluate you and begin to develop your plan of care. This will include risk stratification for sudden cardiac death as well as symptom relief from obstruction to flow of blood. Subsequently, based on your evaluation, they may refer you to their colleagues in electrophysiology, interventional cardiology and cardiothoracic surgery.

Cardiovascular Medicine, Section of Electrophysiology and Pacing
In some patients, implantable cardioverter defibrillator (ICD) devices are required to prevent sudden death in patients with HCM. We have a team of electrophysiologists who specialize in rhythm disorders and devices who are consulted as needed for patients with HCM.
Cardiovascular Medicine, Section of Heart Failure and Transplantation
Some patients with hypertrophic cardiomyopathy may require evaluation by heart failure specialists to provide the best therapies for optimal treatment of heart failure.
Cardiovascular Medicine, Section of Invasive Cardiology
Interventionalists who are part of Hypertrophic Cardiomyopathy Center have experience with alcohol ablation, an interventional approach, used in select patients to treat septal enlargement in hypertrophic cardiomyopathy patients.
The surgical procedure for obstructive hypertrophic cardiomyopathy is called septal myectomy. In some cases, surgery may also be required to repair heart valves affected by HCM.
Our younger patients with hypertrophic cardiomyopathy require a specialized approached by a cardiologist pediatrician.

What to Expect
Whether you are coming to Cleveland Clinic from around the corner or around the world, we want you to know what to expect before, during and after your visit. If you have any questions while reviewing this information, please contact us. We are happy to answer any questions you may have.
Before your appointment
If you are scheduled at least one week away, you will be asked to send in your records, including medical history, test results and films (such as echocardiogram, chest x-ray, MRI or CT as applicable). All information should be sent in the same package (clearly marked with your name and address) via Airborne Express, Federal Express, or certified U.S. mail (make sure you have a tracking number) to the physician with which you have an appointment. The address is:
Hypertrophic Cardiomyopathy Center
9500 Euclid Avenue – Desk J1 - 5
Cleveland, OH 44195

If you are scheduled less than one week out, please bring your records to your appointment.
Travel to Cleveland Clinic
When you make your appointment, we would like to make traveling to Cleveland Clinic as easy as possible. Information on travel to the Miller Family Heart, Vascular & Thoracic Institute.
During your appointment
You will meet with a nurse or a nurse practitioner (NP) who will collect your information, and begin the documentation process.
Depending on where you are in the diagnosis and treatment of your hypertrophic cardiomyopathy, you may be sent for specialized blood tests and imaging tests (electrocardiogram, comprehensive transthoracic echocardiogram, transesophageal echocardiogram, cardiac MR and multidetector CT scanning). All imaging tests will be interpreted by imaging specialists within the Hypertrophic Cardiomyopathy Center.
You will also meet with your HCM Center cardiologist who reviews your records and takes a medical history, performs a physical exam, and advises on consultations with other specialists (cardiac surgeons, invasive cardiologist, and others) within the Center as needed. If you need to meet with one of the multidisciplinary specialists, they will be consulted within a day. The Hypertrophic Cardiomyopathy Center Cardiologist will provide you with a diagnosis and plan of care within 1 to 2 days, depending on testing.
How long will you need to stay at Cleveland Clinic?
Unless a treatment is scheduled at the time of your visit, to complete all testing, you will need to stay in the Cleveland area for 1 to 2 days.
After your visit
Follow up is individualized to the patient. There is an opportunity for virtual visit follow-up as well.
Cleveland Clinic Heart, Vascular & Thoracic Institute physicians, surgeons, and researchers continue to research into new treatments and therapies with the goal of improving patient care and outcomes into the future.
Clinical trials (or research studies) help us create the medicine of tomorrow. They provide hope through offering testing of new drugs, new surgical techniques or other treatments before they are widely available.
We can help you access hundreds of clinical trials across all specialty areas. Our new searchable online trials tool makes identifying treatment opportunities easier than ever.
