title: Chimney technique for mitral valve replacement in children.
abstract: Severe mitral stenosis is unusual in children, but it represents an important challenge for surgeons because of the scarcity of solutions. Several mitral percutaneous and surgical valvuloplasties are performed repetitively to delay mitral valve replacement. Most of the time these procedures show discouraging results. When mitral valve replacement is performed, the annulus may not be large enough to fit a substitute. We present, to our best knowledge, a new technique to implant a large prosthesis in a small annulus without negatively affecting the opening of the leaflets.
