Biography

Vivian Dimas, M.D. is the Director of Interventional Cardiology at Children’s Health℠ and serves as an associate professor of pediatrics at UT Southwestern Medical Center. Dr. Dimas specializes in minimally invasive treatments of heart failure and other complex heart conditions. Dr. Dimas is also board certified in Adult Congenital Heart Disease.

After receiving her medical degree from the University of Oklahoma College of Medicine, Dr. Dimas completed a residency in pediatrics at Children’s Hospital of Oklahoma. She completed her fellowship in pediatric cardiology as well as advanced training in both pediatric interventional cardiology and pediatric heart failure and transplantation at Texas Children’s Hospital.

“I always knew I wanted to enter the field of medicine and care for children,” says Dr. Dimas. “Kids with congenital heart conditions often have a challenging healthcare journey. I love helping treat and manage their heart care as they grow. There is great joy in seeing them live a good quality of life despite living with a congenital heart condition.”

As the Director of Interventional Cardiology, Dr. Dimas leads an expert team of specialists who collaborate in the coordination of care for children who experience common and complex heart conditions. She has expertise in the use of minimally-invasive procedures and advanced techniques, such as percutaneous ventricular assist device implantation,  and transcatheter valve replacement to treat various heart conditions. Dr. Dimas prides herself in ensuring all patients receive the highest level of evidence-based quality care, delivered with compassion.

Dr. Dimas’ research interests involve pioneering the use of Impella percutaneous left ventricle assist devices in the pediatric population as well as the development of a pediatric specific Impella device. These devices help a child’s heart pump blood if they are experiencing heart failure. She strives to adopt the use of this device, as well as other adult cardiac devices such as transcatheter valve replacements, for use in children to improve the treatment and management of congenital heart defects so that children can benefit from the same technological advances available to adults with similar conditions. In addition, she serves as the primary investigator on several new device trials allowing patients at Children’s Health the opportunity to benefit from cutting edge interventional therapies. She is passionate about the discovery of new technologies and approaches to care that improve the quality of life and outcomes of those she serves.

In her free time, Dr. Dimas enjoys spending time with her family, being outdoors, running and cycling. She speaks English and Greek.
