Cardiac-Genetics Clinic

In the Cardiac-Genetics Clinic, we provide comprehensive care for children with cardiac disorders that have a genetic component.

In our Cardiac-Genetics Clinic, we evaluate children with cardiac conditions in conjunction with the Johns Hopkins All Children’s cardiology program. Patients are seen by Melissa Crenshaw, M.D., medical director of the clinical genetics program, and one of our pediatric cardiologists.

You and your child will meet first with a genetic counselor to review your child’s medical history and obtain a complete three-generation family tree and then will meet with Dr. Crenshaw. Dr. Crenshaw will then recommend genetic testing such as chromosomal, metabolic or DNA testing, and echocardiography and EKG testing to review your child’s heart health as needed.

DNA and chromosomal testing require insurance approval. Samples will then be taken at the lab. Results are typically returned within several weeks of your child’s initial visit. Once results are received, we will review the results with you and review recommendations for your child’s treatment.

The conditions we treat in the clinic include:

  • Congenital heart disease
  • Cardiomyopathy
  • Arrhythmias
  • Connective tissue disorders such as Marfan, Ehlers-Danlos, and Loeys-Dietz syndromes

After the initial visit to the clinic, we usually see patients for follow-up appointments every six months to one year, or as needed, depending on your child’s condition. We coordinate directly with your child’s regular physician or specialist throughout your child’s care.

The Cardiac-Genetics Clinic sees patients in the morning on the second and fourth Thursdays of the month. The clinic is located in Johns Hopkins All Children’s Outpatient Care Center on the main campus in St. Petersburg, Florida.
