Michael L. O’Byrne, MD, MSCE, is an interventional cardiologist in the Cardiac Center at Children’s Hospital Philadelphia (CHOP). He is a magna cum laude graduate of Harvard University who earned his MD from Columbia University’s College of Physicians and Surgeons. In 2014, he completed his Master of Science in Clinical Epidemiology at the University of Pennsylvania.
Dr. O’Byrne’s primary clinical focus is on performing cardiac catheterization procedures for children with congenital heart disease, a treatment option that’s less invasive than open heart surgery. He combines his clinical practice with work as a clinical epidemiologist, doing research aimed at understanding how to improve quality of care for children with cardiac disease and their families.
“I think this is a natural combination,” he explained. “My research is grounded by my clinical work, which helps identify and articulate questions that are important to our patients and their families. At the same time, my research informs my clinical care, helping me identify an approach based on the best possible evidence.”
As a researcher, Dr. O’ Byrne receives funding from the NIH/NHLBI. He has authored and peer-reviewed dozens of research papers and abstracts. He was honored in 2017 with the Christopher J White, MD, Early Career Reviewer Award, and was a 2018 AHA Council for Cardiovascular Disease in the Young, Young Investigator Award Finalist.
The collaborative nature of the team at CHOP’s Cardiac Center is a source of inspiration for Dr. O’Byrne. “As interventional cardiologists, we are constantly moving forward together to develop new techniques and ways to help children and their families,” he says. “That means using cutting-edge technology and adapting existing techniques to new applications, both on our own in the cath lab and in cooperation with our surgical colleagues and other cardiologists.”

Patient Experience Ratings
About the Patient Experience Rating System
The Patient Experience Rating is an average of all responses to the care provider related questions shown above from our nationally-recognized Press Ganey Patient Satisfaction Survey. Patients that are treated in outpatient or hospital environments may receive different surveys, and the volume of responses will vary by question.
Responses are measured on a scale of 1 to 5 with 5 being the best score.
We are committed to true transparency. However, to ensure the comments are fair and correctly attributed, we review each one before posting to the website. We exclude entire comments that disclose patient's protected health information, are off-topic, or include other confidential or inappropriate content. Comments will appear on provider bios only if providers have a minimum number of comments.
Comments are shared internally for education purposes to ensure that we are doing our very best for the patients and families for whom we are privileged to care.
The comments are submitted by patients and families and reflect their views and opinions. The comments are not endorsed by and do not reflect the views of Children’s Hospital of Philadelphia.
