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

We have a dedicated cardiac intensive care unit with state-of-the-art technology and an exceptional nursing staff for all cardiac surgical patients. Areas of research interest include: animal models to study techniques that can mitigate neurologic injury on cardiopulmonary bypass, design development of ventricular assist devices and extracorporeal membrane oxygenation (ECMO) and the study of stem cell progenitors responsible for valve repair and regeneration.
