Among the nation's top 10 programs for children with heart disease

Christopher Petit, MD

The Division of Cardiology, formed in 1956 by Dr. Sylvia Griffiths:

  • Provides the latest and most effective diagnostic and therapeutic interventions and surgeries that will achieve the best outcomes
  • Conducts innovative basic science, translational, and clinical research
  • Educates the next generation of pediatric cardiologists in every aspect of pediatric cardiology

Our ultimate goal is to cure heart disease one gene, one cell, one heart at a time through clinical, scientific, and academic excellence.

As part of NewYork-Presbyterian Morgan Stanley Children’s Hospital, we are among the top 10 pediatric cardiology programs in the U.S.

Our Team

Our team of 45 faculty provide clinical excellence through many nationally recognized clinical and research programs, including:

Our program has achieved many measures of distinction. We:

  • Are leaders in the care of babies born with a single ventricle, through our Center for Single Ventricle Care
  • Have expanded the use of 3D pre-procedure planning models to guide surgeries and transcatheter interventions in children born with complex heart lesions, including ventricular assist device placement planning
  • Are pioneers in the initial and ongoing development of transcatheter valve placement for congenital heart disease
  • Have expertise performing the hybrid approach for hypoplastic left heart syndrome, and are one of a few centers in the U.S. to establish a formal pediatric hybrid program
  • Are leaders in treating low-birthweight infants who require early surgical or transcatheter interventions
  • Implanted the first Berlin heart as a bridge to transplant in the youngest patient ever to receive one – an infant only three days old
  • Are one of only a few institutions in the world to perform comprehensive multidisciplinary heart valve repair and replacement
  • Established the only cardiac intensive care unit in the nation exclusively dedicated to the care of newborn infants with congenital heart disease
  • Demonstrated that whole-exome sequencing can serve as a valuable addition to standard prenatal genetic tests, with the potential to improve perinatal care for infants with genetic conditions

The division is also committed to expanding scientific discovery in the field of pediatric cardiology and cardiovascular surgery. To achieve this, several faculty members and staff are currently funded by the National Institutes of Health (NIH), including two R01 awards and a K award, and other large foundations through independent, collaborative, and mentored research awards.


Our Pediatric Cardiology Fellowship is one of the most highly sought after programs in the country. Our three-year bi-campus program involves NewYork-Presbyterian Morgan Stanley Children’s Hospital, on the Columbia University Irving Medical Center campus, and Komansky Children’s Hospital, on the Weill Cornell Medicine campus. Trainees also have the option of an advanced fourth-year fellowship in a subspecialty area such as non-invasive imaging, interventional cardiology, heart failure/transplantation, or pulmonary hypertension.

Patient Story: Mahdi Islam

For six-year-old Mahdi Islam, walking just a few New York City blocks may as well have been scaling Mount Everest. Born in 2010, Mahdi had been diagnosed at birth at Flushing Hospital with Ebstein anomaly, a rare congenital heart defect that impacts the heart’s activity and blood flow.

Patient Spotlight: Kelli MacTaggart

Kelli MacTaggart

Two years ago, Kelli MacTaggart was a typical high school junior. She loved spending time with her friends and family and was looking forward to going off to college. But her life changed suddenly in January 2018, when Kelli became dizzy and lost consciousness while walking with her friends from one class to the next. In the hallway of her high school, she went into cardiac arrest.
