University Hospitals (UH) Rainbow Babies & Children’s Hospital has appointed Robert Gajarski, MD, as the new chief of the Division of Pediatric Cardiology. Dr. Gajarski, a nationally recognized expert in pediatric heart failure and heart transplantation, will oversee the division’s clinical operations, research initiatives, and academic training programs effective October 2024.
Who is Dr. Robert Gajarski?
Dr. Robert Gajarski joins the Cleveland-based health system from Nationwide Children’s Hospital in Columbus, Ohio, where he served as a professor of pediatrics and director of the Pediatric Heart Failure and Transplant Program. According to an official announcement from University Hospitals, his clinical focus centers on the management of complex congenital heart disease, mechanical circulatory support, and long-term outcomes for pediatric transplant recipients.
Board-certified in pediatric cardiology and pediatric transplant hepatology, Dr. Gajarski earned his medical degree from the University of Michigan Medical School. He completed his residency and fellowship training at the University of Michigan and the University of Colorado, respectively. His research, frequently published in peer-reviewed journals such as *The Journal of Heart and Lung Transplantation*, focuses on improving survival rates and quality of life for children requiring advanced cardiac interventions.
What is the role of the Division of Pediatric Cardiology at Rainbow Babies & Children’s?

The Division of Pediatric Cardiology at UH Rainbow Babies & Children’s provides specialized care for infants, children, and adolescents with both congenital and acquired heart conditions. The division functions as a regional referral center for the state of Ohio and the broader Midwest, offering services that include:
- Advanced diagnostic imaging, including fetal echocardiography.
- Interventional catheterization procedures to treat structural heart defects.
- Comprehensive management of pediatric heart failure and mechanical circulatory support devices.
- Collaborative care models involving pediatric cardiothoracic surgeons and intensivists.
By bringing in a leader with Dr. Gajarski’s specific experience in heart failure and transplantation, the hospital aims to strengthen its capacity to manage the most medically complex cardiac cases.
Why this leadership change matters for pediatric heart care
The appointment of a new division chief often signals a strategic pivot in a hospital’s clinical focus. In the competitive landscape of pediatric cardiology, health systems are increasingly prioritizing “centers of excellence” that combine surgical volume with high-level research.
While larger systems like the Cleveland Clinic Children’s also maintain robust pediatric cardiology programs, the addition of Dr. Gajarski positions UH Rainbow Babies & Children’s to deepen its specialized offerings. Historically, the division has focused heavily on long-term follow-up for congenital heart disease survivors. Dr. Gajarski’s background suggests a potential expansion of the hospital’s heart failure and transplant-related infrastructure, an area that requires significant multidisciplinary coordination.
