At Florida Hospital for Children, our highly skilled cardiologists, surgeons and specialists are dedicated to healing kids with heart issues and making their families whole. Just as important, though, we understand that the treatment can sometimes be overwhelming for patients, parents and siblings. That’s why we designed Florida Hospital for Children from the ground up to be a welcoming place for kids where we can take care of their emotional needs, as well as their medical needs.

When your child’s heart beats in an irregular pattern, this is known as an arrhythmia. Fortunately, arrhythmias are highly treatable through a procedure called percutaneous ablation. During this treatment, the tissues that are altering the electrical signals in the heart are cooled to permanently correct the timing of contractions. We’ve joined one of the nation’s leading pediatric congenital heart surgery programs – Johns Hopkins Children's Heart Surgery program – to help deliver world-class surgical care.

Are You Concerned About Your Child’s Heart?

Cardiomyopathy means “a disease of the heart muscle.” It is a rare condition that causes an overly enlarged and thickened heart. It has many different forms and requires a treatment plan that is customized specifically to your child’s needs. If your child’s condition requires surgery, rest assured that he or she will be in the hands of world-class surgeons.

If your child has symptoms of a heart condition or has been diagnosed with one, you might feel overwhelmed with questions and concerns. You are not alone. Our team of medical experts has created a guide to help answer some of the questions you may have, such as:

  • What are the symptoms of heart conditions?
  • How are heart conditions diagnosed?
  • Will heart surgery be necessary for my child?
  • Is pre-natal diagnosis safe?


In valve disease, blood is either not able to flow forward because of a blocked valve, or leaks backward into the heart’s chambers because of a leaking or defective valve. These conditions can cause the heart to work harder, making it more difficult to pump blood to the body as the heart weakens.

Vascular Disease

Our highly advanced diagnostic tools use harmless sound waves to capture accurate images of your baby’s heart before delivery. This allows your doctor to help you make informed decisions about treatment.

Four of the physicians on our cardiology team share their thoughts about the compassionate care they provide, and why it matters to them. “Some people have an affinity for children,” says Constantine Mavroudis, MD. “I guess I’m one of them.”

Meet Dylan Carter and his parents. Today, Dylan is a playful, healthy toddler who, as his dad puts it, “has no limitations and he proves that every day… doing all the things that normal boys do.” This is Dylan’s touching story, starting with a heart murmur his pediatrician detected and his parents’ first visit with Pediatric Cardiologist Gus Ramos, MD.
