After 35 years of cardiac valve replacement, the ideal substitute remains to be found. Homografts are considered best but, due to their scarcity, cannot meet the need of valve replacement. Artificial valves (mechanical or biological) remain the most commonly used but controversy is still present as to the better choice. We tested the Carpentier-Edwards bioprosthesis for its efficacy in valve replacement operations.
