Meryl S. Cohen, MD, is a board-certified pediatric cardiologist in the Cardiac Center at Children's Hospital of Philadelphia (CHOP) with expertise in fetal, transthoracic and transesophageal echocardiography. In addition to her clinical work, she serves as the director of the CHOP Cardiology Fellowship Training program and is an Associate Chief of the Division of Cardiology.

Dr. Cohen’s career in pediatric cardiology grew from a deep interest in the anatomy and physiology of the heart, combined with a passion for taking care of children. According to Cohen, openness and honesty play a large part in her approach. "I try to make sure my patients have a complete understanding of their disease. It’s very important they know what to expect in both the near and distant future."

Communication is also an important part of how she works with the team at the CHOP Cardiac Center to diagnose and treat patients with complex forms of congenital heart disease. "I enjoy figuring out the puzzle of their disease and working collaboratively with my colleagues on ways to provide the best possible care. Teaching and mentoring are primary roles as well. Helping to foster the careers of young trainees is essential to our mission."

As a researcher, Dr. Cohen focuses on understanding growth in children with congenital heart disease. "In particular," she says, "I am working on the risk, timing and cause of obesity in children with heart disease, and how to prevent it. I also use echocardiography (a form of cardiac ultrasound) as a tool to predict outcomes for various forms of congenital heart disease."
