Mighty Max and His One-of-a-Kind Heart follows a small, fluffy dog named Max as he visits the cardiologist and learns about the special care his heart needs. Through stethoscopes, EKG stickers, and clinic rooms, Max helps children see heart care through a lens of comfort, curiosity, and courage. Created especially for children with congenital heart disease and the families who support them, Max's story reminds every child that having a unique heart does not mean being alone.
