Feasibility and early effectiveness of a custom, hand-made systemic atrioventricular valve using porcine extracellular matrix (CorMatrix) in a 4-month-old infant.

A need persists for a prosthetic, systemic atrioventricular valve replacement in the pediatric population that can be customized to a wide range of annular sizes, has a low risk of thrombosis, possesses optimal hemodynamic performance, and has the potential to remodel and grow with the patient. We describe a technique for successful systemic atrioventricular valve replacement in a 4-month-old infant by use of a handmade, bileaflet systemic atrioventricular prosthesis constructed from porcine extracellular matrix.
