Welcome to the

Pediatric & Congenital Heart Program

Our specialized team offers innovative care for infants, children, and adults with congenital heart conditions.

NYU Langone’s Pediatric and Congenital Heart Program, part of Hassenfeld Children’s Hospital, provides high-quality, compassionate medical care for known or suspected congenital heart defects and other congenital heart problems, including childhood arrhythmias, in babies developing in the womb, as well as in infants, children, and adults.

Every year, NYU Langone experts provide about 6,500 outpatient visits for children with congenital heart disease. Our experts diagnose congenital heart disease using the most advanced imaging techniques, such as three-dimensional echocardiography, which uses ultrasound waves to create a highly detailed image of the heart, allowing experts to zero in on the source of the problem. We work with you to make treatment decisions based on your child’s particular condition, in collaboration with cardiologists, cardiac surgeons, and pediatricians.

As part of a world-class academic medical center, we are able to offer patients a full range of therapies and the latest technologies. Therapies for congenital heart disease vary widely, depending on the type and severity of the heart defect, but may include cardiac catheterization and surgery. Our highly experienced surgeons perform about 200 cardiac surgeries each year for congenital heart defects.

We recognize that going to the hospital may be frightening, especially to young children, which is why we make every effort to provide a warm, caring, and comfortable environment for patients and families alike.

Nurse with Patient in Pediatric Intensive Care Unit

We embrace a family-centered care model, where parents are valued partners in the care of their child. Families are encouraged to take an active role in their child's treatment as a member of the healthcare team, participate in daily rounds with our medical staff, and stay with their child overnight in the hospital at their child’s bedside, if they would like.

Pediatric Cardiac ICU Patient with Family

The vast majority of children with heart defects, even those with complex types, spend most of their time at home under their parents' care, requiring only periodic visits to the pediatrician and pediatric cardiologist.
