This case report describes a novel root reconstruction technique for truncal valve insufficiency in a neonate, addressing the challenges of mechanical valve replacement and leaflet-sparing repair in this population. The technique utilized geometry-based root reconstruction guided by body-weight-adjusted reference values to restore physiologic root geometry and preserve the native valve. The successful outcome suggests a potential strategy for durable repair and growth potential in neonatal truncal valve insufficiency.
Geometry-based root reconstruction offers a promising native-tissue approach for truncal valve insufficiency in neonates, potentially avoiding the complications of mechanical valve replacement and promoting growth potential.
Neonatal truncal valve insufficiency carries high postoperative mortality. Mechanical replacement is challenging, and leaflet-sparing repair alone may be insufficient due to fragile tissue and annular dilatation. We report a successful case using geometry-based root reconstruction guided by body-weight-adjusted reference values. This native-tissue approach restored physiologic root geometry, preserved the valve, and enabled growth potential, demonstrating a feasible strategy for durable neonatal repair.
