Heart Center

Meet Your Team

Everyone on the Heart Center team at Seattle Children’s is specially trained to understand and meet the specific healthcare needs of babies, children and adolescents. We treat children with all kinds of heart disease — from the most common to the most complex and rare.

Our pediatric experts work closely with you, with each other and with your child’s pediatrician to provide the best and safest care for your child. We tailor care to your child’s age and developmental stage to protect your child’s health now and as they continue to grow.

Nurse practitioners – cardiology and cardiac surgery

Heart Center nurse practitioners coordinate care for patients and communication between all team members. They are usually the first contact for referring physicians, team physicians and patients. They will provide continuity of care between inpatient and outpatient settings. This includes educating families and staff about heart conditions, ordering diagnostic tests and managing medicines and keeping your family, your child and the referring physician informed about progress. They also visit your child daily while your child is in the hospital.

Nurses – cardiac catheterization lab

Treatment plans can be complex, making our nurses an important resource for families. Their role includes checking to see how your child is doing and coordinating education and care before surgical procedures. They also provide long-term follow-up. Nurses are available to you all along the way to answer questions and give advice. Your child may also work with nurses who have special training and experience in specific areas of the Heart Center, such as electrophysiology. Radiology technicians also play a role in the cath lab, working closely with doctors and nurses to do the imaging that guides your child’s procedure.

ECG technicians

ECG technicians are specially trained medical assistants. They help during exercise testing and heart monitor placement. They also will place electrodes on a patient’s chest and attach the wires that hook up to a machine that records heart rate (electrocardiogram or ECG).

Social worker

Our social worker is available throughout your child’s treatment to help with issues and stresses related to your child’s illness. The social worker collaborates with all members of your child’s healthcare team.

Based on what you, your child or family need, types of help may include emotional support, information about coping with the effect of a heart condition on your family or assistance in getting access to resources.


Children with heart conditions may have challenges or risks related to eating and weight gain, especially during the first years of life. Our nutritionists will work closely with you and your family, your primary physician and your child’s cardiologists to make feeding plans, check calorie intake and track weight gain or loss.
