The majority of congenital heart defects are detected before birth or shortly after—but not always. In this episode, we explore how some heart conditions can go unnoticed until a child faints during sports, struggles to breathe while crawling, or simply seems more tired than usual. Though these cases are less common, they highlight the importance of recognizing subtle signs. With real-life examples, including Bronny James’ cardiac arrest during practice, we speak with a pediatric heart expert from Miller Children’s & Women’s Hospital about what parents should be aware of, how these conditions are diagnosed, and what to do if something doesn’t feel right. It’s a conversation that empowers families with knowledge and awareness.
