Our Hypertrophic Cardiomyopathy Program diagnoses and manages more than 300 patients from before birth to age 21 who either currently have HCM or have a family history of HCM. Our program is one of only two in the U.S. that is recognized as a center of excellence by the Hypertrophic Cardiomyopathy Association.


As part of the program, your child will have access to comprehensive care from our team of HCM experts, including:

  • Cardiologists specializing in HCM and stress echocardiography
  • Cardiologists specializing in cardiac MRIs
  • Cardiac genetic counselors who evaluate your family history
  • Nurses and sonographers who perform echocardiograms
  • Pediatric cardiothoracic surgeons with expertise in ventricular septal reduction surgeries
  • Seamless integration with the adult hypertrophic cardiomyopathy clinic at the Emory University School of Medicine to provide a smooth transition from pediatric to adult care at 21 years of age.
