Biography

Nicolas L. Madsen, M.D., M.P.H., is a Professor in the Department of Pediatrics at UT Southwestern Medical Center. He specializes in pediatric cardiology and congenital heart disease, with a particular focus on hospital-based management.

Dr. Madsen earned his medical degree at the University of Washington, where he also completed a residency in pediatrics and received advanced training through a pediatric cardiology fellowship. Additionally, he holds a master’s degree in public health from the University of Washington.

Certified by the American Board of Pediatrics in pediatric cardiology, Dr. Madsen joined the UT Southwestern faculty in 2021. Previously, he served as Medical Director of the Heart Institute and the Acute Care Cardiology Unit at Cincinnati Children’s Hospital Medical Center.

Dr. Madsen is a nationally recognized clinician and researcher in acute care cardiology and congenital heart disease. He is co-founder and Executive Director of the Pediatric Acute Care Cardiology Collaborative (PAC3), an organization that enables medical professionals across North America to collaborate to improve care of and outcomes in children who are hospitalized with heart conditions.

He serves as Chief of the Division of Pediatric Cardiology as well as Co-Director of the Heart Center at Children’s Health. A Fellow of the American Academy of Pediatrics, he is a member of numerous professional societies, including the American College of Cardiology, the Pediatric Congenital Heart Association, and the American Heart Association.

He has delivered scores of presentations, contributed to books such as Common Cardiac

Issues in Pediatrics, and published a number of academic articles related to his areas of expertise.

“I can think of no greater profession than pediatric cardiology,” Dr. Madsen says. “The opportunities for positive and lasting impact are evident everywhere and across the lifespan. It is a privilege to provide the most advanced clinical care for the benefit of our patients, from the newborn period and throughout their potentially complex journey to adulthood.”
