Nathanya Baez Hernandez, M.D., is a pediatric cardiologist at Children's Health℠ and Assistant Professor at UT Southwestern Medical Center. Dr. Baez Hernandez’s clinical and research interests include caring for children with heart failure. This condition can result from an inherited medical condition, acquired heart disease or graft failure following a heart transplant. Her practice also focuses on treating chemotherapy-induced cardiomyopathy in pediatric cancer survivors and on reducing post-transplant complications.

She is a graduate of Universidad Tecnologica de Santiago, Dominican Republic. Dr. Baez Hernandez completed her first pediatric residency in the Hospital Regional Universitario Dr. Arturo Grullon. She completed her pediatric internship and residency at Marshfield Clinic in Wisconsin and a cardiology fellowship at Advocate Children’s Hospital in Illinois. During her fellowship, she developed an interest in the management of heart failure. In 2019 she became the first graduate of the Pediatric Heart Failure, Ventricular Assist Device (VAD) and Transplantation Fellowship Program at UT Southwestern/Children’s Medical Center, Dallas.

Dr. Baez Hernandez is interested in decreasing pediatric cardiac transplant waitlist mortality, morbidity and duration by improving pediatric heart donor utilization. She is also developing a cardio-oncology multidisciplinary team that focuses on the early identification and treatment of those at risk of cardiac dysfunction. She hopes this effort will positively impact the prevention and reduction of cardiac failure in childhood cancer survivors.

Dr. Baez Hernandez is a member of the International Society for Heart and Lung Transplantation, The Transplantation Society, the American College of Cardiology and the American Academy of Pediatrics.

Dr. Baez Hernandez enjoys sports and considers herself “a fanatic sports woman, always on the run.”
