Christopher J Petit, MD

Pediatric Cardiologist





Dr. Petit is a pediatric interventional cardiologist who joined Sibley Heart Center in 2012. He performs cardiac catheterization procedures on infants, children and adults who have congenital heart disease (CHD). He believes that, often, non-surgical and less-invasive treatment of CHD can offer a quicker recovery time, shorter length of stay in the hospital and better long-term outcomes than other approaches.

Based on a guiding principle that to be a good physician you must be a good teacher, Dr. Petit’s goal is to offer each family affected by CHD an opportunity to acquire expertise in their child’s heart condition. He also believes that teaching medical trainees is an important part of the Sibley mission, and he has won multiple teaching awards over the years.

Dr. Petit advocates for families and patients to take an active role in their care—through medical and catheter procedural planning, including participation in research studies. Dr. Petit is an active participant in multicenter clinical trials through the Pediatric Heart Network, enrolling children with single ventricle heart disease. Further, he has partnered with local CHD families to build the Congenital Catheterization Research Collaborative (CCRC), a multicenter research collaboration based at Children’s Healthcare of Atlanta that includes eight other pediatric heart centers of excellence. Through the CCRC, Dr. Petit and his team have evaluated important innovations in treatment of CHD and shared these lessons with the national CHD community through publications and presentations.

A native of Marietta, Ga., Dr. Petit was excited to return to Atlanta after spending a portion of his career at Children’s Hospital of Philadelphia and Texas Children’s Hospital. His wife, Nina Ham, MD, is a pediatric endocrinologist at Children’s. Together, they have two children.
