Misty Castaneda was born with a heart defect known as tetralogy of Fallot. Told she'd never be able to have children, she was surprised at 19 to discover she was pregnant. Now, 19 years later, Misty has a 19-year-old daughter of her own. Misty has undergone multiple challenges in raising her daughter. Her daughter has had to witness her mother undergo surgery to replace a heart valve and to have a new transcatheter Melody Valve® inserted in her heart. Misty and Milena will talk with Anna about the challenges each of them faced living with tetralogy of Fallot and what others can learn from their experiences.
