Before Navy was born, doctors at Johns Hopkins Children’s Center diagnosed her with a rare congenital heart abnormality called tetralogy of Fallot with an absent pulmonary valve. Because Navy was so small at birth, pediatric cardiac surgeon Bret Mettler suggested she and her parents, Chelsea and David, wait until she got bigger to have surgery to fix her heart defect. After a few months at home, Navy returned to Johns Hopkins in September 2020 to undergo open-heart surgery. #PediatricHeartSurgery #JohnsHopkinsChildrensCenter http://hopkinschildrens.org/heart
