Modified Melody Valve Surgical Implantation in Atrioventricular Position in Four Children Under Two Years of Age.

ABSTRACT: Mitral and tricuspid valve replacement options have traditionally been limited to mechanical valves, bioprostheses, and the mitral Ross procedure. In recent years, the Melody valve (Medtronic, Minneapolis, MN) has emerged as a viable alternative for infants and young children. We present four patients under two years of age who underwent surgical implantation of a modified Melody valve 22 mm in the atrioventricular position. The valve was placed in the mitral position in three patients and the tricuspid position in one. The procedure was performed with palliative intent in all patients, as no alternative surgical options were available. At the time of valve implantation, two patients were supported with venoarterial extracorporeal membrane oxygenation. At the time of this report, two patie
