The Division of Cardiothoracic Surgery treats neonates, infants, children and teens with congenital heart disease. We perform open - and closed-heart surgeries, specializing in single-stage corrective procedures. Services provided by our team include innovative surgical procedures, consultation and surgery for patients with a prenatal diagnosis, surgical repair of complex defects in neonates (including premature and low-birth-weight infants), treating newborns with hypoplastic left-heart syndrome and other complex defects, and heart transplantation (including cardiac assist devices).

We have a dedicated cardiac intensive care unit with state-of-the-art equipment and an exceptional nursing staff for all cardiac surgical patients. Areas of research address pediatric heart failure and include development of an implantable ventricular assist device and the study of intracellular energetics of myocytes relating to the pathophysiology of the failing heart.
