At the CHOC Heart Institute, we understand it may be overwhelming to learn your child has been referred to a heart specialist, a pediatric heart surgeon or has been newly diagnosed with a heart condition. That is why we have assembled a mighty brigade of experts dedicated to caring for children and teens, whether they may be healthy or seriously ill.
Our highly specialized and board-certified pediatric cardiology team and cardiothoracic surgeons provide patients and families with comprehensive care for congenital and acquired heart disease, new symptoms that may be related to the heart, pediatric heart surgery and advanced cardiac services.
Children are not small adults and their health care needs, especially cardiac concerns, should be diagnosed and treated by specialists who understand the needs of children. We are dedicated to providing the least invasive, most advanced treatment for heart-related problems in children. Each patient’s care team includes physicians with specialized cardiac training, pediatric cardiac nurse practitioners, bedside nurses, respiratory therapists, social workers and child life specialists who together provide seamless care, patient education and family support, as well as opportunities for the child to play, discover and create.
