Abstract:
Congenital mitral valve disease is a real challenge in infants and small children. The implantation of expandable stented valves in mitral position has become one of the options of choice in consideration of their acceptable short-term expandable durability and subsequent feasibility of balloon expansion of these devices. We report the first case of a surgical Melody valve-in-valve procedure for early Melody valve degeneration in the mitral position. The result was good, and the procedure safe, rapid, and without an increased risk when a mechanical valve implantation will be necessary.

Heart Valves
The AV valves prevent the backflow of blood from the ventricles to the atria during ventricular contraction. These valves function with the assistance of the chordae tendineae and papillary muscles. When the ventricles are relaxed, the chordae tendineae are slack, allowing blood to flow from the atria into the...
