Hypertrophic Cardiomyopathy Center

VMFH's program designated Center of Excellence

Virginia Mason Franciscan Health (VMFH) and the Center for Cardiovascular Health’s hypertrophic cardiomyopathy (HCM) program has been designated a national Center of Excellence by the Hypertrophic Cardiomyopathy Association (HCMA). Our program is one of only around 50 centers in the country to receive this distinction. The prestigious designation is awarded to HCM programs with strong surgical expertise, a multidisciplinary, patient-centered care approach, high patient volumes, a focus on research, and advanced imaging facilities.

HCM is a genetic condition that causes your heart muscle to thicken. If the heart muscle becomes too thick, it can block or reduce blood flow out of your heart. Without treatment, it can lead to serious complications, including sudden cardiac death.

Hypertrophic cardiomyopathy center in the Puget Sound: Why choose us?

VMFH is the only comprehensive HCM center in Washington state, with a robust presence in Seattle, Tacoma and Silverdale. Highlights of our care include: 

  • Center of Excellence designation: The program’s rapid growth and dedicated team have earned it national recognition, marking it as the first HCM center in CommonSpirit Health to achieve this honor. The center performs the highest number of myectomy surgeries and provides the broadest selection of specialized medication treatment options in the state.
  • Team of experts: Our HCM specialists review your case before creating your customized care plan. You have a team of cardiologists, cardiac surgeons, interventional cardiologists, anesthesiologists, radiologists, pharmacists, nurses, and social workers by your side at every step. Meet our team
  • HCM surgery expertise: Septal myectomy is a specialized HCM surgery that requires a high level of experience and skill. Our team is among the top 2% of centers in the nation in terms of septal myectomy volume and experience. Research shows that surgeons who have more experience provide better outcomes for patients.

  • Minimally invasive options: Alcohol septal ablation is a minimally invasive procedure to treat HCM. Our interventional cardiologists have performed a high volume of these procedures, leading to excellent results and faster recovery.

  • Award-winning care: U.S. News & World Report ranked our cardiology, heart and vascular surgery program No. 1 in Washington, Alaska, Montana, Idaho and Oregon for the 2023-2024 award period. We also earned a Cardiac Care Outcomes Assessment Program Performance Recognition Award from the Foundation for Health Care Quality. These accolades reflect our commitment to exceptional care and positive outcomes.

  • Genetic testing and counseling: Our team evaluates patients and families for genetic cardiovascular conditions. We offer at-home genetic testing options, so patients receive prompt diagnosis and treatment. After you receive test results, our genetic counselors provide compassionate guidance on family planning and treatment decisions. When needed, we also refer patients to cardiologists who specialize in maternal-fetal medicine, pediatrics and women’s health and pregnancy-related heart disease.

  • Research focus: We are a strong research-based institution, partnering with the world-leading Benaroya Research Institute. As our patient, you may have access to groundbreaking new therapies through our national and international clinical trials. For information about research opportunities and enrolling in clinical trials for HCM, visit Benaroya Research Institute.

Our patients share their stories
“When you need open heart surgery, you look for the best team," says Juanita Labosier. “I was so impressed with the teamwork of the whole department, from the cardiologists and surgeons to every member of the staff. They communicated and worked together very well.” Read our patient stories.

What does hypertrophic cardiomyopathy feel like?

HCM doesn’t always cause symptoms, but people with the condition may experience:

  • Arrythmias
  • Chest pain, especially during exercise
  • Dizziness 
  • Fainting or lightheadedness 
  • Fatigue
  • Shortness of breath during exercise
  • Swelling in your abdomen, ankles, feet, or legs

What causes hypertrophic cardiomyopathy?

HCM is caused by abnormal genes that thicken your heart muscle. It typically affects the wall (septum) between the lower heart chambers (ventricles). You can develop HCM if you inherit one of the HCM genes. 

In most cases, you have a 50% chance of inheriting the gene if one parent carries it. If one of your relatives has HCM, ask your provider about HCM screening and the role of genetic testing.

Hypertrophic cardiomyopathy diagnosis

Diagnosing HCM requires an evaluation of your symptoms and family history combined with advanced cardiac imaging tests. HCM specialists at Virginia Mason Franciscan Health provide the necessary tests and interpret your results. 

Typically, we diagnose HCM using noninvasive tests like cardiac MRI, echocardiogram and electrocardiogram (EKG). We also provide genetic testing for you or your family members when needed. Learn more about our diagnosis and testing for HCM and other heart conditions.

Treatments for hypertrophic cardiomyopathy

Our dedicated program provides the most effective HCM treatments available. Your treatment may include:

  • Medications can relieve symptoms like shortness of breath and swelling.

    Our center was among the first in the Pacific Northwest to offer mavacamten (Camzyos®), the only FDA-approved medication that targets the thickened heart muscle and relieves HCM symptoms. Our patients also have access to ongoing clinical trials where we explore the newest therapies.

  • Our comprehensive cardiac rehabilitation program includes an expert team and services that aren’t widely available in other programs. In addition to exercise, we offer cooking classes and nutrition guidance. We also provide intensive cardiac rehabilitation (ICR) for patients with more complex heart health needs. Learn more about cardiac rehabilitation.

  • If HCM causes an arrhythmia, a device such as an implantable cardioverter defibrillator or a pacemaker may restore a normal heart rhythm or prevent a life-threatening complication.

    Our electrophysiologists and interventional cardiologists work together to provide the latest devices to treat HCM. Learn more about pacemakers and implantable devices.

  • Alcohol septal ablation is a minimally invasive procedure that helps thin the ventricular septum.

    Our interventional cardiologists have years of experience with this procedure. Alcohol septal ablation may benefit you if medications aren’t enough to relieve symptoms, but you are not a candidate for surgery.

  • Our heart surgeons are leaders in septal myectomy, an open-heart procedure to treat HCM. We perform more surgeries than most other centers, and our patients have consistently positive outcomes. 

    Learn more about cardiac surgery.

  • For patients who require advanced heart failure care, we have a team of experts as well as transplant cardiologists. Our team provides the left ventricular assist device (LVAD) and seamless referrals for those who need a heart transplant. Learn more about our heart failure program.

  • Within our HCM center, we have advanced diagnostics capabilities including genetic testing for patients and their families, cardiac MRI and cardiopulmonary exercise testing.

  • We offer preconception counseling and pre-pregnancy risk evaluation for women with HCM as well as cardiology care during pregnancy.
