Seattle Children’s Heart Center is co-led by Mark Lewin, MD, division chief, Pediatric Cardiology; Jonathan Chen, MD, division chief, Congenital Cardiac Surgery; and Joanie Blanchard, RN, MN, NE-BC, director.

The Heart Center team includes specialists who treat children from infancy through young adulthood with all kinds of heart disease – from the most common to the most complex and rare.

We work closely with you, with each other, and with your child’s pediatrician to provide the best and safest care for your child.

Pediatric Heart Specialists (Cardiologists)

Our board-certified pediatric cardiologists diagnose, treat and manage the care of children of all ages with heart problems.

Pediatric Cardiac Surgeons

Seattle Children’s board-certified pediatric cardiac surgeons perform a wide range of heart procedures, including surgical repair of complex congenital heart defects.

Cardiac Anesthesiologists

Our pediatric cardiac anesthesia service is provided by a group of specially trained doctors who know how a child with heart disease may react to anesthesia. They and their team of nurse anesthetists and nurse practitioners will meet with you before the procedure.

They will provide the anesthetic for children undergoing full cardiac surgery as well as for those needing cardiac catheterization or electrophysiology studies.

Cardiac Intensivists

Cardiac intensivists are doctors with special training in pediatric cardiac intensive care. We have the only pediatric Cardiac Intensive Care Unit (CICU) in the Pacific Northwest. At least one of our cardiac intensive care doctors is present in the CICU 24 hours a day, 7 days a week.

Cardiac Perfusion Team

The cardiac perfusion team specializes in the circulation of blood outside of the body (extracorporeal circulation). They operate the heart-lung bypass machine for patients during congenital heart surgery procedures and provide heart and lung support using ventricular assist devices (VADs).

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 medications, keeping your family, your child and the referring physician informed about progress and visiting your child daily while they are in the hospital.

Nurses

Treatment plans can be complex, so our nurses are 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.

Your child may also work with nurses who have special training and experience in specific areas of the Heart Center, such as electrophysiology.

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.

Depending 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 the family or assistance in getting access to resources.

Nutritionists

Children with heart conditions may have challenges or cardiac risk factors 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 develop feeding plans, monitor calorie intake and track weight gain or loss.
