Children’s Heart Institute

The Children’s Heart Institute is a team of highly-regarded pediatric cardiology specialists in Maryland and Virginia who provide comprehensive diagnostic and therapeutic services for children who are suspected of having heart disease. At the Children’s Heart Institute, we take a family approach to medical care. In addition to the attending pediatric cardiologist, the practice also utilizes the expert medical services of pediatric sub-specialists for non-cardiac problems.

The institute provides services for the unborn, children, and young adults up to 21 years of age. Adults with Congenital Heart Disease are treated in conjunction with their adult cardiologists and referring physicians.
