High early mortality after mitral replacement in young children warrants cautious selection; Level 3 data leaves open optimal timing versus repair strategies.

Mitral-valve replacement in children under 6 years of age carries a high initial risk but offers satisfactory long-term survival and functional outcomes, particularly with mechanical prostheses.
Thomas Günther Pomorski (2000) conducted a cohort in Congenital mitral-valve disease (n=35). Mitral-valve replacement was evaluated on Hospital mortality. Mitral-valve replacement in children under 6 years of age had an overall hospital mortality of 17.1% and an actuarial survival of 51.2% at 20 years.
