While repair remains the preferred approach for mitral valve disease, valve replacement is the only therapeutic option for cases in which repair is not feasible or does not yield lasting benefit. MVR in the first few years of life poses a challenge mostly due to the small size of the mitral valve annulus, LV and left atrium. Early experience with bioprosthetic valves in the 1970s and early 1980s revealed limited valve longevity due to intrinsic calcification, a process that appeared to be accelerated in children 8–10.
