Pediatric Cardiothoracic Surgery Team at Betty Irene Moore Children's Heart Center

Heart defects in children are complex and unique, and require the expertise of many specialists from a variety of disciplines. The Moore Children’s Heart Center has developed a collaborative, multidisciplinary approach to caring for your child who may need cardiothoracic surgery.

Our team performs more than 700 open-heart surgeries each year (significantly more than at other children’s hospitals in the country) and despite of the complexity of pediatric heart conditions we see, we manage to have remarkable results—for children of all ages.

Our Pediatric Cardiothoracic Surgery team members are certified by the American Board of Thoracic Surgery, the American Board of Surgery, and/or the Royal College of Physicians and Surgeons. All our heart surgery doctors teach at the Stanford University School of Medicine.
