Director, Advanced Heart Failure and Cardiomyopathy
Dr. Jefferies, an associate professor of pediatric cardiology and adult cardiovascular diseases within the University of Cincinnati College of Medicine, is the director of Advanced Heart Failure / Cardiomyopathy in the Heart Institute at Cincinnati Children's Hospital Medical Center.
He completed his combined pediatric and adult cardiology training at the Baylor College of Medicine in Houston, Texas at the Texas Children's Hospital and the Texas Heart Institute. He has authored or co-authored over 120 peer-reviewed manuscripts and book chapters on cardiomyopathy, cardiovascular genetics, and adults with congenital heart disease.
His current research interests include heritable causes of cardiovascular disease, novel drug therapies for advanced heart failure, novel gene discovery in cardiomyopathy, characterization and management of left ventricular noncompaction (LVNC), and early diagnosis and management of chemotherapy induced cardiotoxicity.
He is on the editorial board of the Texas Heart Institute Journal and is an active member of numerous professional organizations, including the Heart Failure Society of America, the American College of Cardiology and the American Heart Association. He is the lead editor for two textbooks that focus on the management of heart disease in children and young adults entitled “Heart Failure in the Child and Young Adult: From Bench to Bedside” and “Cardioskeletal Myopathies in Children and Young Adults.”

Cardiomyopathy; heart failure; heart transplantation; mechanical circulatory support
Thomas D Ryan, MD, PhD, was born and raised in Wichita, KS and graduated magna cum laude from Wichita State University in 1996 with a BS in biological sciences.
In 1997 he began training in the MD/PhD program at the University of Alabama at Birmingham, and studied the molecular, cellular, and whole organ aspects of cardiac remodeling in a rat model of volume overload. His general pediatrics residency training took place at Cincinnati Children’s Hospital Medical Center from 2006-2009, as did his pediatric cardiology fellowship training from 2009-2012 and advanced fellowship in Pediatric Heart Failure/Transplant from 2012-2013. His clinical and research interests focus on heart failure, cardiomyopathy, cardiac transplantation, and mechanical circulatory support.
