title: A novel technique of supra-annular mitral valve replacement.
abstract: We describe a new technique of mitral valve replacement in an 11.5-month-old, 5.5 kg baby whose native mitral annulus was only 14 mm. We successfully implanted a 16-mm mechanical valve in the supra-annular position by sewing it into a short polytetrafluoroethylene graft that was then sutured to the native annulus.
