Welcome to

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 heart problems in babies developing in the womb, as well as infants, children, and adults. 

Our cardiologists diagnose congenital heart defects and heart disease using the most advanced techniques, such as three-dimensional echocardiography, which uses ultrasound waves to create a highly detailed image of the heart to zero in on the source of the problem. We work with you to make treatment decisions on a case-by-case basis, 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. Medication and watchful waiting may be all that is required for certain conditions, such as heart defects that cause a small- or medium-sized opening, which often close or reduce in relative size as a child ages.

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.

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.

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.
