As the Director of the Fetal Heart Program and the Fontan Rehabilitation, Wellness, Activity and Resilience Development (FORWARD) Program at Children’s Hospital of Philadelphia (CHOP), Dr. Rychik specializes in the early detection and long-term treatment of complex forms of heart disease and developmental abnormalities. He holds the Robert and Dolores Harrington Endowed Chair in Pediatric Cardiology.
The mission of the Fetal Heart Program is to offer compassionate, state-of-the-art care to the fetus and the family. “I focus on the bookends of care, in addition to the spectrum of what happens in between,” explains Dr. Rychik. “From the earliest point of detection into early adulthood, we are about creating survival and improving the quality of life.”
Early detection affords Dr. Rychik more time for what he views as one of the most important parts of his job — patient and family education. “For me it’s about providing clarity,” he says. “Through direct communication, written materials, diagrams, videos and imaging, we are now able to communicate conditions and care strategies much more effectively.”
Dr. Rychik’s passion for his life’s work is clearly evident. “The exciting thing for me is knowing that there are things I can do, before birth, that can affect what that child and adult is going to eventually be like,” he says. “That’s a profound and wondrous thing.”
As leader of the Single Ventricle Survivorship Clinic, Dr. Rychik is focused on improving therapies. He’s studying the long-term effects of current management strategies for single ventricle conditions. As he explains, “Until recently, children and young adults with these conditions have simply not walked the earth. Treating them is both a challenge and a blessing.”
Dr. Rychik has also been instrumental in contributing to the field’s knowledge about the cardiac aspects of other congenital conditions. For example, he developed the unique CHOP Scoring System for Twin-Twin Transfusion Syndrome, a potentially fatal condition where twins sharing a placenta experience uneven blood flow. This system allows doctors to better learn the extent of the condition and determine the best approach to treatment.
He serves on the editorial board of numerous national and international journals, and is a frequent lecturer and presenter at national and international pediatric cardiac conferences on complex cardiovascular disease in both fetal and pediatric patients.
Dr. Rychik has authored more than 250 peer-reviewed research publications, books, reviews, and chapters on fetal and pediatric cardiac disorders and treatment. He is the author of a book entitled Fetal Cardiovascular Imaging: A Disease-Based Approach, which is considered one of the definitive texts on the subject of imaging and management of fetal heart disease.
Dr. Rychik recently established and now leads the CHOP Cardiac Center “FORWARD” Program — a pioneering clinical and investigational effort focused on Fontan Rehabilitation, Wellness and Resilience Development. The endeavor builds upon the Single Ventricle Survivorship Clinic. It aims to bring specialized services to this unique population by offering exercise rehabilitation, mental health and behavioral care, nutrition and dietary needs, and patient-family education to those with a single ventricle and Fontan circulation.

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.
