The Children’s Heart Center Team

The multidisciplinary team of affiliated physicians at McGovern Medical School at UTHealth work collaboratively to provide comprehensive care to babies prior to birth, infants, children and young adults with complex heart conditions. Continued advancements in nonsurgical treatments enable the physicians to provide patients with conservative care, when appropriate. When pediatric cardiovascular surgery is required, the team of specialists provides specialized care focused on the best possible outcome for each child.

With a Level IV Neonatal Intensive Care Unit (NICU) and a dedicated Children’s Heart Center Intensive Care Unit at Children’s Memorial Hermann Hospital, patients have access to the highest level of specialized cardiac care by a team of nurses, affiliated physicians, therapists and other allied healthcare professionals specialized in pediatric heart conditions.
