Description
Han Ki Park comments in 2026 on a fresh clue for choosing heart repair in babies with borderline left hearts. Some newborns have a small left side of the heart plus a narrowed or broken aortic arch. Surgeons must guess whether the left side can grow enough for a two-chamber repair.
Size scores alone predict that growth poorly, Park notes. He discusses a study of 161 infants where pressure across a hole between the upper chambers tracked later growth of the mitral valve. Flow-based signs like this one may sharpen choices that size alone cannot settle. Better prediction matters because a failed two-chamber repair often ends badly.
