Sweet Isabella was held by her mother Jessica for just a few moments before being whisked away for her first heart surgery at just 14 hours old. Born with pulmonary atresia with intact ventricular septum, half of Isabella’s heart was severely underdeveloped causing major issues with blood flow from her heart to her lungs.

Isabella’s condition is one of the most high-risk congenital heart conditions, and the affiliated team at Children’s Memorial Hermann Hospital and UTHealth Houston knew the journey would be difficult. But one thing was for sure, the love of a mother can never be underestimated!

Experience Isabella’s journey through the Complex Neonatal Heart program at the Children’s Heart Institute and see how the family is doing today.
