Cardiac Programs and Services in Florida

Cardiothoracic Surgery

Renowned pediatric cardiothoracic surgeons at Nemours treat nearly all heart defects using the most innovative, up-to-date approaches. We have special expertise in treating single-ventricle anomalies, including the Fontan procedure, and repairing many heart abnormalities in one operation during infancy. 

As a volunteer participant in the Society for Thoracic Surgery’s national congenital heart surgery database of procedures and outcomes, we share our surgical data with the public to highlight our commitment to the highest quality care.

Cardiology (Outpatient)

Nemours Cardiac Center experts help children with congenital heart defects — and all types of acquired heart disease — with diagnosis, evaluation, treatment and follow-up care. The Nemours Cardiac Center in Florida is an integrated network designed to help Florida families get expert heart care closer to home.

Cardiac Imaging and Diagnostic Tests

Nemours Cardiac Center teams perform state-of-the-art pediatric diagnostic tests such as electrocardiogram (EKG), echocardiography (echo), fetal echo, cardiac event monitoring, Holter monitors and more. Some advanced cardiac imaging and diagnostic tests are performed at Nemours Children’s Hospital in Orlando (NCH).

Electrophysiology and Arrhythmia Program

Nemours cardiologists and electrophysiologists (or EP doctors) diagnose and treat heart rhythm problems in kids, from the tiniest newborns to teens.

Fetal Diagnostics

As early as the 16th week of pregnancy, Nemours cardiology teams provide fetal heart evaluations and fetal echocardiography (echo) to find out what’s happening inside your baby’s tiny heart. Together with your family and obstetrician or maternal-fetal medicine specialist, we plan for treatment right after your child is born. As part of our mobile cardiology services, we also dispatch teams to collaborating hospitals and facilities across the state for fetal evaluations and diagnostics.

Cardiac Anesthesia

Like all kids, children with heart problems may need routine procedures such as ear tubes and tonsillectomies. Our cardiac anesthesiologists understand your child’s heart condition, and will assist in every cardiac and noncardiac procedure your child needs. Cardiac anesthesiologists also offer sedation for MRI and CT scans when needed.

Cardiac Intensive Care Unit

Pediatric cardiology intensivists and nurses offer critical care services for children with complex heart conditions and after noncardiac surgeries. Cardiac critical care is available at the modern, high-tech cardiac intensive care unit (CICU) at Nemours Children’s Hospital in Orlando.

The center is organized as an integrated practice unit, allowing staff to work as a barrier-free, coordinated team. Our facilities are designed to provide the very best care to our patients and families. All diagnostic, treatment and recovery areas are contiguous, spacious and modern with the latest equipment. Cardiologists also care for babies in the onsite neonatal intensive care unit (NICU) and the NICUs at collaborating hospitals across the state.

Nemours Cardiac Center, Orlando at Nemours Children’s Hospital offers extracorporeal membrane oxygenation (ECMO), a specialized cardiac and respiratory support system that helps children who are experiencing cardiac and or respiratory failure. Our experienced experts provide ECMO support to newborns, older infants, children and teens in need of cardiopulmonary support.

Preventive Cardiology

Preventive cardiology experts in the Nemours Cardiac Center in Florida evaluate and offer guidance for kids dealing with conditions that could put them at risk for heart issues (e.g., hardening of the arteries, obesity, high blood pressure). This care may include a referral to our Healthy Choices Clinic and support services from a clinical dietitian.

Cardiologists who are part of the Nemours Cardiac Center also provide expert pediatric telecardiology services to collaborating hospitals throughout the state via Nemours CareConnect or telecardiology.

  • CareConnect is a technological link that remotely brings pediatric specialists from Nemours “into” the collaborating facility using an iPad so the specialists can visually assess a child and help make a determination about care or pediatric transport.
  • Telecardiology services are provided when facilities connect using secure access to a child's electronic health record or cardiac testing, which is then interpreted by one of our pediatric cardiologists. The way a child’s heart functions is vastly different than an adult’s, so these services allow better quality care for kids in remote locations.  
Cardiovascular Genetics Program

Many cardiac conditions are caused, in part, by changes in genes that are important for the heart to develop and function normally. When the cause of a heart condition may be genetic, Nemours geneticists and counselors can provide in-depth testing and analysis, and will help your family understand the affects the heart condition could have on your child, siblings and future generations.

  • DiGeorge Syndrome
    Also called 22q11.2 deletion syndrome, children with DiGeorge syndrome often have a congenital heart defect (present at birth) such as interrupted aortic arch, truncus arteriosus, tetralogy of Fallot or ventricular septal defect. Our Cardiac Center surgeons and care teams have expertise in treating kids with 22q11.2 and hold special clinic days coordinated with other specialists your child may see. We also keep close contact with your child’s primary care doctor and provide long-term condition monitoring and management.  
  • Down Syndrome
    An estimated 50 percent of babies born with Down syndrome have or will develop heart problems later in life. Our cardiology team coordinates with onsite neuromuscular specialists to evaluate and regularly monitor for congenital (present at birth) heart defects, such as atrioventricular and ventricular septal defects and tetraology of Fallot. With early diagnosis and advanced treatment, we can do a lot to protect your child’s heart now, and in the future. 
  • Williams Syndrome
    Williams syndrome is a genetic disorder that causes a narrowed aorta, the main artery carrying blood from the heart to the body (also called supravalvar aortic stenosis, or SVAS), and sometimes a narrowed pulmonary artery, which carries blood from the heart to the lungs. Our Williams syndrome clinic offers coordinated care by pediatric specialists representing multiple medical disciplines.

Single-Ventricle Program

Newborns with single-ventricle defects, like hypoplastic left heart syndrome (HLHS), require a series of procedures in infancy and childhood to improve circulation. In addition to fetal echocardiography, heart surgery and interventional cardiology, we provide multispecialty interstage care to support healthy growth for infants between the first two operations. This means your child can see a cardiologist, dietitian, feeding and swallowing therapist, neurodevelopmental specialist and others as needed on the same day. 

Williams Syndrome Program

Williams syndrome is a rare genetic disorder that affects the physical development of multiple body functions — particularly the heart and circulatory system. Cardiologists at Nemours Cardiac Center, Orlando have extensive experience in treating Williams syndrome. Our Chief of Cardiology, Dr. Gul Dadlani, offers families a clinic day just for kids with Williams syndrome, so they can see all the appropriate specialists and complete any necessary tests in much less time than separate visits would require.
